Compose Editing Evolved: Schema-Driven and Context-Aware

Every day, thousands of developers are creating and editing Compose files. At Docker, we are regularly adding more features to Docker Compose such as the new provider services capability that lets you run AI models as part of your multi-container applications with Docker Model Runner. We know that providing a first-class editing experience for Compose files is key to empowering our users to ship amazing products that will delight their customers. We are pleased to announce today some new additions to the Docker Language Server that will make authoring Compose files easier than ever before.

Schema-Driven Features

To help you stay on the right track as you edit your Compose file, the Docker Language Server brings the Compose specification into the editor to help minimize window switching and keeps you in your editor where you are most productive.

Context-Aware Intelligence

Although attribute names and types can be inferred from the Compose specification, certain attributes have a contextual meaning on them and reference values of different attributes or content from another file. The Docker Language Server understands these relationships and will suggest the available values so that there is no guesswork on your part.

Figure 2: Code completion understands how your files are connected and will only give you suggestions that are relevant in your current context.

Freedom of Choice

The Docker Language Server is built on the Language Server Protocol (LSP) which means you can connect it with any LSP-compatible editor of your choosing. Whatever editor you like using, we will be right there with you to guide you along your software development journey.

Figure 3: The Docker Language Server can run in any LSP-compliant editor such as the JetBrains IDE with the LSP4IJ plugin.

Conclusion

Docker Compose is a core part of hundreds of companies’ development cycles. By offering a feature-rich editing experience with the Docker Language Server, developers everywhere can test and ship their products faster than ever before. Install the Docker DX extension for Visual Studio Code today or download the Docker Language Server to integrate it with your favourite editor.

Docker Unveils the Future of Agentic Apps at WeAreDevelopers

Agentic applications – what actually are they and how do we make them easier to build, test, and deploy? At WeAreDevelopers, we defined agentic apps as those that use LLMs to define execution workflows based on desired goals with access to your tools, data, and systems. 

While there are new elements to this application stack, there are many aspects that feel very similar. In fact, many of the same problems experienced with microservices now exist with the evolution of agentic applications.

Therefore, we feel strongly that teams should be able to use the same processes and tools, but with the new agentic stack. Over the past few months, we’ve been working to evolve the Docker tooling to make this a reality and we were excited to share it with the world at WeAreDevelopers.

Let’s unpack those announcements, as well as dive into a few other things we’ve been working on!

WeAreDeveloper keynote announcements

Mark Cavage, Docker’s President and COO, and Tushar Jain, Docker’s EVP of Product and Engineering, took the stage for a keynote at WeAreDevelopers and shared several exciting new announcements – Compose for agentic applications, native Google Cloud support for Compose, and Docker Offload. Watch the keynote in its entirety here.

Compose has evolved to support agentic applications

Agentic applications need three things – models, tools, and your custom code that glues it all together. 

The Docker Model Runner provides the ability to download and run models.

The newly open-sourced MCP Gateway provides the ability to run containerized MCP servers, giving your application access to the tools it needs in a safe and secure manner.

With Compose, you can now define and connect all three in a single compose.yaml file! 

Here’s an example of a Compose file bringing it all together:

# Define the models
models:
gemma3:
model: ai/gemma3

services:
# Define a MCP Gateway that will provide the tools needed for the app
mcp-gateway:
image: docker/mcp-gateway
command: –transport=sse –servers=duckduckgo
use_api_socket: true

# Connect the models and tools with the app
app:
build: .
models:
gemma3:
endpoint_var: OPENAI_BASE_URL
model_var: OPENAI_MODEL
environment:
MCP_GATEWAY_URL: http://mcp-gateway:8811/sse

The application can leverage a variety of agentic frameworks – ADK, Agno, CrewAI, Vercel AI SDK, Spring AI, and more. 

Check out the newly released compose-for-agents sample repo for examples using a variety of frameworks and ideas.

Taking Compose to production with native cloud-provider support

During the keynote, we shared the stage with Google Cloud’s Engineering Director Yunong Xiao to demo how you can now easily deploy your Compose-based applications with Google Cloud Run. With this capability, the same Compose specification works from dev to prod – no rewrites and no reconfig.

With Google Cloud Run (via gcloud run compose up) and soon Microsoft Azure Container Apps, you can deploy apps to serverless platforms with ease. It already has support for the newly released model support too!

Compose makes the entire journey from dev to production consistent, portable, and effortless – just the way applications should be.

Learn more about the Google Cloud Run support with their announcement post here.

Announcing Docker Offload – access to cloud-based compute resources and GPUs during development and testing

Running LLMs requires a significant amount of compute resources and large GPUs. Not every developer has access to those resources on their local machines. Docker Offload allows you to run your containers and models using cloud resources, yet still feel local. Port publishing and bind mounts? It all just works.

No complex setup, no GPU shortages, no configuration headaches. It’s a simple toggle switch in Docker Desktop. Sign up for our beta program and get 300 free GPU minutes!

Getting hands-on with our new agentic Compose workshop

Selfie with at the end of the workshop with attendees

At WeAreDevelopers, we released and ran a workshop to enable everyone to get hands-on with the new Compose capabilities, and the response blew us away!

In the room, every seat was filled and a line remained outside well into the workshop hoping folks would leave early to open a spot. But, not a single person left early! It was so thrilling to see attendees stay fully engaged for the entire workshop.

During the workshop, participants were able to learn about the agentic application stack, digging deep into models, tools, and agentic frameworks. They used Docker Model Runner, the Docker MCP Gateway, and the Compose integrations to package it all together.

Lightning talks that sparked ideas

Lightning talk on testing with LLMs in the Docker booth

In addition to the workshop, we hosted a rapid-fire series of lightning talks in our booth on a range of topics. These talks were intended to inspire additional use cases and ideas for agentic applications:

Digging deep into the fundamentals of GenAI applications

Going beyond the chatbot with event-driven agentic applications

Using LLMs to perform semantic testing of applications and websites

Using Gordon to build safer and more secure images with Docker Hardened Images

These talks made it clear: agentic apps aren’t just a theory—they’re here, and Docker is at the center of how they get built.

Stay tuned for future blog posts that dig deeper into each of these topics. 

Sharing our industry insights and learnings

At WeAreDevelopers, our UX Research team was able to present their findings and insights after analyzing the past three years of Docker-sponsored industry research. And interestingly, the AI landscape is already starting to have an impact in language selection, attitudes toward trends like shifted-left security, and more!

Bringing a European Powerhouse to North America

In addition to the product announcements, we announced a major co‑host partnership between Docker and WeAreDevelopers, launching WeAreDevelopers World Congress North America, set for September 2026. Personally, I’m super excited for this because WeAreDevelopers is a genuine developer-first conference – it covers topics at all levels, has an incredibly fun and exciting atmosphere, live coding hackathons, and helps developers find jobs and further their career!

The 2026 WeAreDevelopers World Congress North America will mark the event’s first major expansion outside Europe. This creates a new, developer-first alternative to traditional enterprise-style conferences, with high-energy talks, live coding, and practical takeaways tailored to real builders.
