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.

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.
