The short version: #Docker acquired a fantastic company called Infinit. Using their technology, we will provide secure distributed storage out of the box, making it much easier to deploy stateful services and legacy enterprise applications on Docker. This will be delivered in a very open and modular design, so operators can easily integrate their existing storage systems, tune advanced settings, or simply disable the feature altogether. Oh, and we’re going to open-source the whole thing.
The slightly longer version:
At Docker we believe that tools should adapt to the people using them, not the other way around. So we spend a lot of time searching for the most exciting and powerful software technology out there, then integrating it into simple and powerful tools. That is how we discovered a small team of distributed systems engineers based out of Paris, who were working on a next-generation distributed filesystem called Infinit. From the very first demo two things were immediately clear. First, Infinit is an incredible piece of technology with the potential to change how applications consume and produce data; Second, the Infinit and Docker teams were almost comically similar: same obsession with decentralized systems; same empathy for the needs of both developers and operators; same taste for simple and modular designs.
Today we are pleased to announce that Infinit is joining the Docker family. We will use the Infinit technology to address one of the most frequent Docker feature requests: distributed storage that “just works” out of the box, and can integrate existing storage system.
Docker users have been driving us in this direction for two reasons. The first is that application portability across any infrastructure has been a central driver for Docker usage. As developers rapidly evolve from single container applications to multi-container applications deployed on a distributed system, they want to make sure their entire application is portable across any type of infrastructure, whether on cloud or on premise, including for the stateful services it may include. Infinit will address that by providing a portable distributed storage engine, in the same way that our SocketPlane acquisition provided a portable distributed overlay networking implementation for Docker.
The second driver has been the rapid adoption of Docker to containerize stateful enterprise applications, as opposed to next-generation stateless apps. Enterprises expect their container platform to have a point of view about persistent storage, but at the same time they want the flexibility of working with their existing vendors like HPE, EMC, Nutanix etc. Infinit addresses this need as well.
With all of our acquisitions, whether it was Conductant, which enabled us to scale powerful large-scale web operations stacks or SocketPlane, we’ve focused on extending our core capabilities and providing users with modular building blocks to work with and expand. Docker is committed to open sourcing Infinit’s solution in 2017 and add it to the ever-expanding list of infrastructure plumbing projects that Docker has made available to the community, such as InfraKit, SwarmKit and Notary.
For those who are interested in learning more about the technology, you can watch Infinit CTO Quentin Hocquet’s presentation at Docker Distributed Systems Summit last month, and we have scheduled an online meetup where the Infinit founders will walk through the architecture and do a demo of their solution. A key aspect of the Infinit architecture is that it is completely decentralized. At Docker we believe that decentralization is the only path to creating software systems capable of scaling at Internet scale. With the help of the Infinit team, you should expect more and more decentralized designs coming out of Docker engineering.
A few Words from CEO and founder Julien Quintard –
“We are thrilled to join forces with Docker. Docker has changed the way developers work in order to gain in agility. Stateful applications is the natural next step in this evolution. This is where Infinit comes into play, providing the Docker community with a default storage platform for applications to reliably store their state be it for a database, logs, a website’s media files and more.”
A few details about the Infinit’ architecture:

Infinit&8217;s next generation storage platform has been designed to be scalable and resilient while being highly customizable for container environments. The Infinit storage platform has the following characteristics:
&8211; Software-based: can be deployed on any hardware from legacy appliances to commodity bare metal, virtual machines or even containers.
&8211; Programmatic: developers can easily automate the creation and deployment of multiple storage infrastructure, each tailored to the overlying application&8217;s needs through policy-based capabilities.
&8211; Scalable: by relying on a decentralized architecture (i.e peer-to-peer), Infinit does away with the leader/follower model, hence does not suffer from bottlenecks and single points of failure.
&8211; Self Healing: Infinit&8217;s rebalancing mechanism allows for the system to adapt to various types of failures, including Byzantine.
&8211; Multi-Purpose: the Infinit platform provides interfaces for block, object and file storage: NFS, SMB, AWS S3, OpenStack Swift, iSCSI, FUSE etc.

Global Mentor Week: Thank you Docker Community!

Danke, рақмет сізге, tak, धन्यवाद, cảm ơn bạn, شكرا, mulțumesc, Gracias, merci, asante, ευχαριστώ, thank you #Docker community for an incredible Docker Global Mentor Week! From Tokyo to Sao Paulo, Kisimu to Copenhagen and Ottowa to Manila, it was so awesome to see the energy from the community coming together to celebrate and learn about Docker!

Over 7,500 people registered to attend one of the 110 mentor week events across 5 continents! A huge thank you to all the Docker meetup organizers who worked hard to make these special events happen and offer Docker beginners and intermediate users an opportunity to participate in Docker courses.
None of this would have been possible without the support (and expertise!) of the 500+ advanced Docker users who signed up as mentors to help newcomers #LearnDocker.
Whether it was mentors helping attendees, newcomers pushing their first image to Docker Hub or attendees mingling and having a good time, everyone came together to make mentor week a success as you can see on social media and the Facebook photo album.
Here are some of our favorite tweets from the meetups:

Learn Docker
In case you weren’t able to attend a local event, the five courses are now available to everyone online here: https://training.docker.com/instructor-led-training
Docker for Developers Courses
Developer &8211; Beginner Linux Containers
This tutorial will guide you through the steps involved in setting up your computer, running your first containers, deploying a web application with Docker and running a multi-container voting app with Docker Compose.
Developer &8211; Beginner Windows Containers
This tutorial will walk you through setting up your environment, running basic containers and creating a Docker Compose multi-container application using Windows containers.
Developer &8211; Intermediate (both Linux and Windows)
This tutorial teaches you how to network your containers, how you can manage data inside and between your containers and how to use Docker Cloud to build your image from source and use developer tools and programming languages with Docker.
Docker for Operations courses
This courses are step-by-step guides where you will build your own Docker cluster, and use it to deploy a sample application. We have two solutions for you to create your own cluster.

Using play-with-docker

Play With Docker is a Docker playground that was built by two amazing Docker captains: Marcos Nils and Jonathan Leibiusky during the Docker Distributed Systems Summit in Berlin last October.
Play with Docker (aka PWD) gives you the experience of having a free Alpine Linux Virtual Machine in the cloud where you can build and run Docker containers and even create clusters with Docker features like Swarm Mode.
Under the hood DIND or Docker-in-Docker is used to give the effect of multiple VMs/PCs.
To get started, go to http://play-with-docker.com/ and click on ADD NEW INSTANCE five times. You will get five &8220;docker-in-docker&8221; containers, all on a private network. These are your five nodes for the workshop!
When the instructions in the slides tell you to &8220;SSH on node X&8221;, just go to the tab corresponding to that node.
The nodes are not directly reachable from outside; so when the slides tell you to &8220;connect to the IP address of your node on port XYZ&8221; you will have to use a different method.
We suggest to use &8220;supergrok&8221;, a container offering a NGINX+ngrok combo to expose your services. To use it, just start (on any of your nodes) the jpetazzo/supergrok image. The image will output further instructions:
docker run –name supergrok -d jpetazzo/supergrok
docker logs –follow supergrok
The logs of the container will give you a tunnel address and explain you how to connected to exposed services. That&8217;s all you need to do!
You can also view this excellent video by Docker Brussels Meetup organizer Nils de Moor who walks you through the steps to build a Docker Swarm cluster in a matter of seconds through the new play-with-docker tool.

Note that the instances provided by Play-With-Docker have a short lifespan (a few hours only), so if you want to do the workshop over multiple sessions, you will have to start over each time &8230; Or create your own cluster with option #2 below.

Using Docker Machine to create your own cluster

This method requires a bit more work to get started, but you get a permanent cluster, with less limitations.
You will need Docker Machine (if you have Docker Mac, Docker Windows, or the Docker Toolbox, you&8217;re all set already). You will also need:

credentials for a cloud provider (e.g. API keys or tokens),
or a local install of VirtualBox or VMware (or anything supported by Docker Machine).

Full instructions are in the prepare-machine subdirectory.
Once you have decided what option to choose to create your swarm cluster, you ready to get started with one of the operations course below:
Operations &8211; Beginner
The beginner part of the Ops tutorial will teach you how to set up a swarm, how to use it to host your own registry, how to build your app container images and how to deploy and scale a distributed application called Dockercoins.
Operations &8211; Intermediate
From global container scheduling, overlay networks troubleshooting, dealing with stateful services and node management, this tutorial will show you how to operate your swarm cluster at scale and take you on a swarm mode deep dive.

Docker for AWS Public Beta

Today, we’re announcing that #Docker for AWS is graduating to public beta, just in time for AWS re:Invent. Docker for AWS is a great way for ops to setup and maintain secure and scalable Docker deployments on AWS. With Docker for AWS, IT ops teams can:

Deploy a standard Docker platform to ensure teams can seamlessly move apps from developer laptops to Dockerized staging and production environments, without risk of incompatibilities or lock-in.
Integrate deeply with underlying infrastructure to ensure Docker takes advantage of the host environment’s native capabilities and exposes a familiar interface to administrators.
Deploy the platform to all the places where you want to run Dockerized apps, simply and efficiently
Make sure the latest and greatest Docker versions are available for the hardware, OSs, and infrastructure you love, and provide solid upgrade paths from one Docker version to the next.

To try the latest Docker for AWS beta based on the latest Docker Engine betas, click the button below:

Docker for AWS works fully within AWS free tier, giving you the ability to try it out at no cost (just create a 1-manager, 1-worker swarm). Installation takes a few minutes, and will give you a fully functioning swarm, ready to deploy and scale Dockerized apps.
We first unveiled the Docker for AWS private beta on stage at DockerCon 2016 back in June, and we are excited to be opening up to beta to the public. We received lots of great feedback from private beta testers (thanks!) and incorporated as much of it as possible. Enhancements added during the private beta include:

All container logs are automatically sent to AWS CloudWatch for later inspection and analysis. That means you no longer have to rummage around on hosts to find the error you’re looking for or worry that logs are lost if a worker is replaced.
Built-in diagnose tool lets you submit a swarm-wide diagnostic dump to Docker so that we can help diagnose and troubleshoot a misbehaving Docker for AWS swarm.
Configurable ephemeral instance root disk size and type lets you choose faster SSDs and bigger disks to hold all your images, containers and volumes.
Improved upgrade stability so that you can confidently upgrade your Docker for AWS to the latest version

We’re particularly proud of the progress we’ve made on diagnostics and upgradability. These are features that set a true production system apart from simple fire-and-forget templates that just spin up resources without thought for debugging or future upgrades.
The improvements added during the private beta complement the initial features Docker for AWS launched with earlier this year:

Simple access and management using EC2 keypairs
Quick and secure deployment of websites thanks to auto-provisioned and auto-configured load balancers
Secure and easy-to-manage EC2 network and instance configuration

With today’s public beta announcement, we hope to get even more users interested in running Docker on AWS and testing the beta. Check out the detailed docs and sign up on beta.docker.com to be notified of updates and new beta versions.

What To Expect from Docker at AWS re:Invent 2016

It’s the age of IT transformation. Spurred on by developers, adoption of #Docker containers has empowered application teams to transform the way they build, ship and run applications, allowing for faster and more frequent delivery. Initially seen as a tool mainly for developers, Docker is now at the center of key enterprise initiatives, and has attracted the attention of IT operations teams. Enterprise IT ops teams use Docker to maintain control over their environment and boost security as they embrace cloud strategies like hybrid cloud and multi-cloud.

Docker at #AWS re:Invent 2016
This adoption of Docker within the cloud is why we are excited to be at AWS re:Invent 2016. If you’re going to be at the show, we hope you stop by booth #622. Docker employees will be showing live demos, and will be on hand to answer questions. We’ll of course be passing out free Docker swag as well.
This year we’ll be showing two types of demos at the booth:
1. Docker Datacenter (DDC) demo – In this demo attendees will learn about Docker Datacenter, our commercial solution that delivers an enterprise container management platform. The platform is supported by Docker and is built specifically to give developers and IT operations teams agility, portability and control for their applications. It is integrated with the latest version of Docker engine, Engine 1.12 delivering a set of features that make enterprise IT application team’s lives easier as they embrace cloud and hybrid cloud.
2. Docker for AWS demo – This demo will teach attendees about Docker for AWS which is now available as a public beta! Docker for AWS is the easiest way for IT applications teams to setup and configure an install of Docker Engine 1.13, on their AWS resources. The tool allows for full use of all Docker APIs and enables IT ops teams to manage, deploy and scale dockerized applications across their EC2 infrastructure.

Docker Datacenter for AWS Customers
In addition to helping developers deliver applications more quickly by enabling them to self-service, there are several benefits for IT ops. Docker Datacenter allows sysadmins and Cloud Engineers to manage, deploy and scale containers across any infrastructure within their environment, including AWS EC2 instances. As part of the solution, customers have access to features in Docker CS Engine 1.12 (includes built-in orchestration, load balancing, service discovery, mutual TLS encryption for clusters etc.), allowing them to quickly create secure clusters and deploy containerized applications onto nodes within the clusters (this can be done based on resource availability). Teams can then easily scale the number of nodes and containers as needed. In addition, the portability of Docker allows IT ops to avoid lock-in and migrate application workloads to the infrastructure that makes the most business sense. But DDC doesn’t just deliver portability, it provides the necessary tools for IT ops to maintain control over their apps running in the cloud.
IT ops can rest assured that their applications are secure. DDC’s role-based access controls limit who has access to resources, and Docker Content Trust image signing ensures Docker images within the registry are current and untampered. Teams can even enforce policies that permit only applications with signed images to run in production. This makes cloud technology like AWS a safer place for IT operations teams to run their mission-critical applications.
AWS re:Invent 2016 is less than a week away, and we can’t wait! Feel free to stop by booth 622 if you’ll be at the show. If you would like to see a demo, you can register ahead of time and get a chance to win some VIP Docker swag at the end of each demo. But don’t worry, if you can’t make it to any of the scheduled demo sessions, just stop by the booth and we’ll be more than happy to speak with you.

Introducing the Docker Community Directory and Docker Community Slack

Today, we’re thrilled to officially introduce the #Docker Community Directory and Slack to further enable community building and collaboration. Our goal is to give everyone the opportunity to become a more informed and engaged member of the community by creating sub groups and channels based on location, language, use cases, interest in specific Docker-centric projects or initiatives.

Sign up for the Docker Community Directory and Slack

Docker Community Directory
Members who join the Docker Community Directory will benefit from the following:

Latest product updates and release notes
Targeted invitations and promo codes for Docker community events (DockerCon, Docker Summits, Meetups, Docker Partner events, trainings, workshops and hackathons)
Ability to participate in raffles for Docker Swag
Chance to get priority access to product betas
Opportunity to get involved as a user and/or customer reference, meetup organizer, mentor, speaker, etc.
Be listed on the Docker Community Directory without sharing your email (built in direct messaging system)
Access to the Docker Community Slack

The Docker Community Directory is a tool for community members to collaborate. Everyone should use it respectfully, with genuine and specific Docker-centric messages. It should not be used to send messages that could be qualified as spam or otherwise violate Docker’s community code of conduct. We invite community members who think the directory is not being used properly by one member to reach out to community@docker.com with more information, so that we can address the situation accordingly. Those members not abiding by the community code of conduct and misusing the platform will be subject to a warning and potential removal from the directory.
Docker Community Slack
We launched the Docker Community Slack a few months ago, so that the Docker Team could easily collaborate with two key groups of amazing contributors: Docker Captains and Docker Meetup Organizers. After a few weeks of planning and figuring out the best way to proceed, we are now ready and excited to extend the invitation to the broader community!
Due to a high level of engagement, our Slack team reaches the 10,000 messages archive limit very quickly, you might not able to see older slack messages. Everyone interested in seeing or searching older messages can look at our Community Slack archive here: dockercommunity.slackarchive.io
How can I be invited to join?
Docker has set up a registration form. Provide the information required and a Slack invite will be sent to you. You can also contact community@docker.com if you have any questions or concerns.
What’s the Docker Community Slack URL ?
Once you’ve received the invitation and joined our slack team, you can go to dockercommunity.slack.com to login.
Who are the admins of the Docker Community Slack?
Karen Bajza (@kbajza), Lisa McNicol (@lisa.mcnicol), Sophia Parafina (@spara), Mano Marks (@mano), Jenny Burcio (@jenny), Sebastiaan van Stijn (@thajeztah) and Victor Coisne (@vcoisne) are the current administrators of the Docker Community Slack team and private channels. They are also in charge of monitoring compliance with the code of conduct. If you witness inappropriate behaviour, please reach out to one of us so that we can respond appropriately.
Who should I contact if I want to create a new public or private channel?
The Docker Community Team is the central authority for this Slack team. If you’re interested in creating a new public or private channel for your topic of interest, language or location, please reach out to one of the administrators listed above.
What happens to the IRC and Gitter channels?
The IRC and Gitter channels will be closed down. We will post an announcement on those channels before closing, so that users have time to register for Slack. We have enabled gateway access for users that prefer using XMPP or IRC client. Instructions for connecting an XMPP or IRC client can be found on the Slack website.

What’s New in Docker Datacenter with Engine 1.12 – Demo Q&A

Last week we announced the latest release of #Docker #Datacenter (DDC) with Engine 1.12 integration, which includes Universal Control Plane (UCP) 2.0 and Docker Trusted Registry (DTR) 2.1. Now, IT operations teams can manage and secure their environment more effectively and developers can self-service select from an even more secure image base. Docker Datacenter with Engine 1.12 boasts improvements in orchestration and operations, end to end security (image signing, policy enforcement, mutual TLS encryption for clusters), enables Docker service deployments and includes an enhanced UI. Customers also have backwards compatibility for Swarm 1.x and Compose.

To showcase some of these new features we hosted a webinar where we provided an overview of Docker Datacenter, talked through some of the new features and showed a live demo of solution. Watch the recording of the webinar below:

We hosted a Q&A session at the end of the webinar and have included some of the most common audience questions received.
Audience Q&A
Can I still deploy run and deploy my applications built with a previous Docker Engine version?
Yes. UCP 2.0 automatically sets up and manages a Swarm cluster alongside the native built-in swarm-mode cluster from Engine 1.12 on the same set of nodes. This means that when you use “docker run” commands, they are handled by the Swarm 1.x part of the UCP cluster and thus ensures full backwards compatibility with your existing Docker applications. The best part is, no additional product installation or configuration is required by the admin to make this work.In addition to this, previous versions of the Docker Engine (1.10 and 1.11) will still be supported as part of Docker Datacenter.

Will Docker Compose continue to work in Docker Datacenter? I.e Deploy containers to multiple hosts in a DDC cluster, as opposed to only on a single host?
In UCP, “docker-compose up” will deploy to multiple hosts on the cluster. This is different from an open-source Engine 1.12 swarm-mode, where it will only deploy on a single node, because UCP offers full backwards compatibility (using the parallel Swarm 1.x cluster, as described above). Note that you will have to use Compose v2 in order to deploy across multiple hosts, as Compose v1 format does not support multi-host deployment.

For the built in HTTP routing mesh, which External LB’s are supported? Nginx, HAProxy, AWS EC2 Elastic LB? Does this work similar to what Interlock was doing?
The experimental HTTP routing mesh (HRM) feature is focused on providing correct routing between hostnames and services, so it will work across any of the above load balancers, as long as you configure them appropriately for this purpose.
The HRM and Interlock LB/SD feature sets provide similar capabilities but for different application architectures. HRM is used for swarm-mode based services, while Interlock is used for non-swarm-mode “docker run” containers.
For more information on these features, check out our blog post on DDC networking updates and the updated reference architecture linked within that post.

Will the HTTP routing mesh feature be available also in the open source free version of the docker engine?
Docker Engine 1.12 (open-source) contains the TCP-based routing mesh, which allows you to route based on ports. Docker Datacenter also provides the HTTP routing mesh feature which extends the open-source feature to allow you to route based on hostnames.

What is “docker service” used for and why?
A Docker service is a construct within swarm-mode that consists of a group of containers (“tasks”) from the same image. Services follow a declarative model that allows you to specify the desired state of your application: you specify how many instances of the container image you want, and swarm-mode ensures that those instances are deployed on the cluster. If any of those instances go down (e.g. because a host is lost), swarm-mode automatically reschedules them elsewhere on the cluster. The service also provides integrated load balancing and service discovery for its container instances.

What type of monitoring of host health is built in?
The new swarm-mode in Docker Engine 1.12 uses a RAFT-based consensus algorithm to determine the health of nodes in the cluster. Each swarm manager sends regular pings to workers (and to other managers) in order to determine their current status. If the pings return an unhealthy response or do not meet the latency minimums for the cluster (configurable in the settings), then that node might be declared unhealthy and containers will be scheduled elsewhere in the cluster. In Universal Control Plane (UCP), the status of nodes is described in detail in the web UI on the dashboard and Nodes pages.

What kind of role based access controls (RBAC) are available for networks and load balancing features?
The previous version of UCP (1.1) had the ability to provide granular label-based access control for containers. We’ve since expanded that granular access control to include both services and networks, so you can use labels to define which networks a team of users has access to, and what level of access that team has. The load balancing features make use of both services and networks so will be access controlled through those resources.

Is it possible to enforce a criteria that only allows production DTR run only containers that are signed?
Yes, you can accomplish this using a combination of features in the new version of Docker Datacenter. DTR 2.1 contains a Notary server (Docker Content Trust), which allows you to provide your users cryptographic keys to sign images. UCP 2.0 has the ability to run only signed images on the cluster. Furthermore, you can use “delegations” to define which teams must sign the image prior to it being deployed; for example in a low security cluster you could allows any UCP user to sign, whereas in production, you might require signatures from Release Management, Security, and Developer teams. Learn more about running images with Docker Content Trust here.

As a very large enterprise doing various POC&8217;s for Docker, one of the big questions is vulnerabilities in the open source code that can be part of the base images. Is there anything that Docker is developing to counter this?
Earlier this year, we announced Docker Security Scanning, which provides a detailed security profile of Docker images for risk management and software compliance purposes. Docker Security Scanning is currently available for private repositories in Docker Cloud private and coming soon to Docker Datacenter.

Is there any possibility to trace which user is accessing a container?
Yes, you can use audit logging. To provide auditing of your cluster, you can utilize UCP’s Remote Log Server feature. This allows you to send system debug information to a syslog server of your choice, including a full list of all commands run against the UCP cluster. This would include information such as which user attempted to deploy or access a container.

What checks does the new DDC have for potential noisy neighbor container scenarios, or for rogue containers that can potentially hog the underlying infrastructure?
One of the ways you can provide a check against noisy neighbor scenarios is through the use of runtime resource constraints. These allow you to set limits on how much system resources (e.g. cpu, memory) that any given container is allowed to use. These are configurable within the UI.

Do you have a trial license for Docker Datacenter ?
We offer a free 30-day trial of Docker Datacenter. Trial software can be accessed by visiting the Docker Store – www.docker.com/trial

For pricing, is a node defined as a host machine or a container?
The subscription is licensed and priced on a per node per year basis. A node is anything with the Docker Commercially Supported (CS) Engine installed on it. It could be a bare metal server, cloud instance or within a virtual machine. More pricing details are available here.

Kompose: a tool to go from Docker-compose to Kubernetes

Editor’s note: Today’s post is by Sebastien Goasguen, Founder of Skippbox, showing a new tool to move from ‘docker-compose’ to Kubernetes.At Skippbox, we developed kompose a tool to automatically transform your Docker Compose application into Kubernetes manifests. Allowing you to start a Compose application on a Kubernetes cluster with a single kompose up command. We’re extremely happy to have donated kompose to the Kubernetes Incubator. So here’s a quick introduction about it and some motivating factors that got us to develop it.Docker is terrific for developers. It allows everyone to get started quickly with an application that has been packaged in a Docker image and is available on a Docker registry. To build a multi-container application, Docker has developed Docker-compose (aka Compose). Compose takes in a yaml based manifest of your multi-container application and starts all the required containers with a single command docker-compose up. However Compose only works locally or with a Docker Swarm cluster.But what if you wanted to use something else than Swarm? Like Kubernetes of course.The Compose format is not a standard for defining distributed applications. Hence you are left re-writing your application manifests in your container orchestrator of choice.We see kompose as a terrific way to expose Kubernetes principles to Docker users as well as to easily migrate from Docker Swarm to Kubernetes to operate your applications in production.Over the summer, Kompose has found a new gear with help from Tomas Kral and Suraj Deshmukh from Red Hat, and Janet Kuo from Google. Together with our own lead kompose developer Nguyen An-Tu they are making kompose even more exciting. We proposed Kompose to the Kubernetes Incubator within the SIG-apps and we received approval from the general Kubernetes community; you can now find kompose in the Kubernetes Incubator.Kompose now supports Docker-compose v2 format, persistent volume claims have been added recently, as well as multiple container per pods. It can also be used to target Openshift deployments, by specifying a different provider than the default Kubernetes. Kompose is also now available in Fedora packages and we look forward to see it in CentOS distributions in the coming weeks.kompose is a single Golang binary that you build or install from the release on GitHub. Let’s skip the build instructions and dive straight into an example.Let’s take it for a spin!Guestbook application with DockerThe Guestbook application has become the canonical example for Kubernetes. In Docker-compose format, the guestbook can be started with this minimal file:version: “2”services: redis-master: image: gcr.io/google_containers/redis:e2e ports: – “6379” redis-slave: image: gcr.io/google_samples/gb-redisslave:v1 ports: – “6379” environment: – GET_HOSTS_FROM=dns frontend: image: gcr.io/google-samples/gb-frontend:v4 ports: – “80:80″ environment: – GET_HOSTS_FROM=dnsIt consists of three services. A redis-master node, a set of redis-slave that can be scaled and find the redis-master via its DNS name. And a PHP frontend that exposes itself on port 80. The resulting application allows you to leave short messages which are stored in the redis cluster.To get it started with docker-compose on a vanilla Docker host do:$ docker-compose -f docker-guestbook.yml up -dCreating network “examples_default” with the default driverCreating examples_redis-slave_1Creating examples_frontend_1Creating examples_redis-master_1So far so good, this is plain Docker usage. Now let’s see how to get this on Kubernetes without having to re-write anything.Guestbook with ‘kompose’Kompose currently has three main commands up, down and convert. Here for simplicity we will show a single usage to bring up the Guestbook application.Similarly to docker-compose, we can use the kompose up command pointing to the Docker-compose file representing the Guestbook application. Like so:$ kompose -f ./examples/docker-guestbook.yml upWe are going to create Kubernetes deployment and service for your dockerized application.If you need more kind of controllers, use ‘kompose convert’ and ‘kubectl create -f’ instead.INFO[0000] Successfully created service: redis-masterINFO[0000] Successfully created service: redis-slaveINFO[0000] Successfully created service: frontendINFO[0000] Successfully created deployment: redis-masterINFO[0000] Successfully created deployment: redis-slaveINFO[0000] Successfully created deployment: frontendApplication has been deployed to Kubernetes. You can run ‘kubectl get deployment,svc’ for details.kompose automatically converted the Docker-compose file into Kubernetes objects. By default, it created one deployment and one service per compose services. In addition it automatically detected your current Kubernetes endpoint and created the resources onto it. A set of flags can be used to generate Replication Controllers, Replica Sets or Daemon Sets instead of Deployments.And that’s it! Nothing else to do, the conversion happened automatically.Now, if you already now Kubernetes a bit, you’re familiar with the client kubectl and you can check what was created on your cluster.$ kubectl get pods,svc,deploymentsNAME READY STATUS RESTARTS AGEfrontend-3780173733-0ayyx 1/1 Running 0 1mredis-master-3028862641-8miqn 1/1 Running 0 1mredis-slave-3788432149-t3ejp 1/1 Running 0 1mNAME CLUSTER-IP EXTERNAL-IP PORT(S) AGEfrontend 10.0.0.34 <none> 80/TCP 1mredis-master 10.0.0.219 <none> 6379/TCP 1mredis-slave 10.0.0.84 <none> 6379/TCP 1mNAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGEfrontend 1 1 1 1 1mredis-master 1 1 1 1 1mredis-slave 1 1 1 1 1mIndeed you see the three services, the three deployments and the resulting three pods. To access the application quickly, access the _frontend_ service locally and enjoy the Guestbook application, but this time started from a Docker-compose file.Hopefully this gave you a quick tour of kompose and got you excited. They are more exciting features, like creating different type of resources, creating Helm charts and even using the experimental Docker bundle format as input. Check Lachlan Evenson’s blog on using a Docker bundle with Kubernetes. For an overall demo, see our talk from KubeConHead over to the Kubernetes Incubator and check out kompose, it will help you move easily from your Docker compose applications to Kubernetes clusters in production.Download KubernetesGet involved with the Kubernetes project on GitHub Post questions (or answer questions) on Stack Overflow Connect with the community on SlackFollow us on Twitter @Kubernetesio for latest updates
