Docker Captain Take 5 – Gianluca Arbezzano

Docker Captains are select members of the community that are both experts in their field and are passionate about sharing their Docker knowledge with others. “Docker Captains Take 5” is a regular blog series where we get a closer look at our Captains and ask them the same broad set of questions ranging from what their best Docker tip is to whether they prefer cats or dogs (personally, we like whales and turtles over here). Today, we’re interviewing Gianluca Arbezzano who has been a Docker Captain since 2016. He is a Senior Software Staff Engineer at Equinix Metal and is based in Italy. 

How/when did you first discover Docker?

At this point, it is not easy to pick a date. Four years ago I was in Dublin away from my home town near Turin. The Docker Meetup along with many other meetups were a great opportunity for nerds like me looking for new friends and to grab free pizza while having a good time. Back then I was working for a company that helps businesses move to the cloud. I saw that Docker was a powerful tool to master. Not only was Docker a useful tool and led me to meet a lot of cool people, but it also helped me to become a better open source citizen and enabled me to have some awesome experiences.

What is your favorite Docker command?

I am an old-style Docker user. Many of the new cool commands are unknown to me. One of the powerful combos I use from time to time is still “docker rm -fv $(docker ps -aq)”– I know, there are better ways! It clearly shows how powerful a good CLI tool and the UNIX philosophy are. I love buildkit, so buildx is also something I use a lot.

What is your top tip that you think other people don’t know about working with Docker?

Do not look at Docker just as the end tool. Look at how the CLI is friendly, the simplicity in writing and reading a Dockerfile. The composition with containerd and runc. The tool itself is just the tip of the iceberg.

What’s the coolest Docker demo you have done/seen ?

Do you know what I love more than watching developers sharing how they set up their workstation and how they take care of their “way of working”? Maintaining my own dotfiles and taking care of my way of working! https://www.youtube.com/watch?v=cYsVvV1aVss Jess Frazel is amazing at sharing and hacking its own environment!

What have you worked on in the past six months that you’re particularly proud of?

I am working at Tinkerbell, a bare metal provisioner that we open source at Equinix Metal. It is now part of the CNCF and my goal is to make it battle-tested and to meet a lot of bare metal enthusiasts that want to know more about how we manage data centers at Equinix Metal.

What do you anticipate will be Docker’s biggest announcement next year?

M1, ARM, AMD and many more. The hardware is coming back to life and the time where Intel was the way to go is over. This is fun, but it adds another variable to our equation. I think Docker will play a major role here with its ability to describe how an application runs and how it gets built.

What do you think is going to the biggest challenge that we, the Docker community, will face in 2021?

Docker is now on everybody’s laptop, but the ecosystem and the developers around the world changed drastically in the last 2-3 years. Containers are not a general purpose technology. Docker needs to keep its UX friendly approach and keep making tools that developers enjoy using. As I told you, I am the kind of user that stopped picking up new Docker features two years ago probably because I like what I know and it is enough for my daily job. But buildkit and buildx made me get back hacking more with containers for example.

What are some personal of your goals for the next year with respect to the Docker community?

I am very picky when it comes to selecting tools for my daily work. I value them a lot and I want to know them perfectly. A new CLI tool takes months of evaluation before being added or removed from my list of everyday utilities. My goal is to find what Docker is uniquely good at. That will sound weird but as I said, things are not like they were six years ago. Nowadays we have more options and experiences.

What talk would you most love to see at DockerCon 2021?

“How Docker increases development ergonomics.”

Looking to the distant future, what is the technology that you’re most excited about right now and that you think holds the most promise?

WASM! 

Rapid Fire Questions

What new skills have you mastered or tried to learn during the pandemic?

I bought a house in February, so everything required to get it up and ready! Heavy lifting, cleaning everything multiple times and so on.

Cats or Dogs?

I have one dog and two cats. I love them all!

Salty, sour or sweet?

Salty.

Beach or mountains?

Based on which direction I drive, I can be skiing in one hour or swimming in two hours. No reason to pick only one!

Year in Review: The Most Viewed Docker Blog Posts of 2020 Part 2

It’s end of year round up time! The first post in this series covered the number 10-6 most viewed Docker blog posts. If you were wondering what the #1 most viewed blog post of the year was, then keep reading. The suspense will soon be over…

 5) How to Develop Inside a Container Using Visual Studio Code Remote Containers

VS Code is another beloved tool. This guest post from Docker Community Leader Jochen Zehnder included some handy tricks for the Visual Studio Code Remote Containers extension that allows you to develop inside a container. 

4) How to deploy on remote Docker hosts with docker-compose

There was some solid Compose momentum this year. This how-to post showed an example of how to access remote docker hosts via SSH and tcp protocols in hopes to cover a large number of use-cases.

3) How To Use the Official NGINX Docker Image

NGINX is super popular, so naturally so was this tutorial that took a look at the NGINX Official Docker Image and how to use it. 

2) Containerized Python Development – Part 1

This post contained tips for how to containerize a Python service/tool and the best practices for it. Fun fact: the second post in this series was the #8 most viewed post of the year. The more you know! 

1) Apple Silicon M1 Chips and Docker

The most viewed blog post we published in 2020 covered the status of Docker on M1 chips. Lots of excitement about the new silicon and we are working to make it the best experience for developers. We are on it, promise. In fact, you can download and try the tech preview of Docker Desktop for M1 here. 

And here’s a bonus treat for those who made it this far – our top educational content of the year! The most popular webinars were From Docker Straight to AWS, Find and Fix Container Image Vulnerabilities with Docker and Snyk and Adding Container Security to Docker Hub. The most popular workshops were Getting Started with Docker, I Didn’t Know I Could Do That with Docker – AWS ECS Integration and I Didn’t Know I Could Do That with Docker – Python Developers. 

Ahhh some good times we had indeed in 2020. Thanks to everyone who learned and shared with us. What type of Docker content would you like to see in 2021? Let us know on Twitter!

Year in Review: The Most Viewed Docker Blog Posts of 2020 Part 1

2020 was some type of year…as we wrap up a year that undoubtedly will never be forgotten, we rounded up the most viewed Docker blog posts. The following posts are some of what you, the Docker community, found to be most interesting and useful. Which was your favorite?

10) Announcing the Compose Specification

Starting the list with a *bang* is a post highlighting that we created a new open community to develop the Compose Specification. This new community is run with open governance and with input from all interested parties, allowing us together to create a new standard for defining multi-container apps that can be run from the desktop to the cloud. 

9) Advanced Dockerfiles: Faster Builds and Smaller Images Using BuildKit and Multistage Builds 

This post showed some more advanced patterns that go beyond copying files between a build and a runtime stage, allowing one to get the most out of the multistage build feature. Who doesn’t want more efficient multistage Dockerfiles? 

8) Containerized Python Development – Part 2

The second in a series, this post discussed how to set up and wire other components to a containerized Python service. It showed a good way to organize project files and data and how to manage the overall project configuration with Docker Compose. Also covered were the best practices for writing Compose files for speeding up our containerized development process.

7) Docker Desktop for Windows Home is here! 

We were super stoked to announce that the first version of Docker Desktop for Windows Home was available! It was great to get started with WSL 2 Docker Desktop on Windows home and hear the community’s feedback. 

6) Scaling Docker to Serve Millions More Developers: Network Egress

The second in a series, this blog post takes a deep dive into rate limits for container image pulls. Interestingly, roughly 30% of all downloads on Hub come from only 1% of our anonymous users.

But wait, where are the top five posts? And what was the #1 most viewed post of the year? Stay tuned for Part 2 of this series where all will be revealed and we can relive the goodness that was the Docker blog 2020
