Intellisense is not showing up while writing docker compose file, even pressing ctrl+space key is not showing any suggestion.
Thanks

Hey @ashish-thakur111, this is by-design. We're in the process of implementing a proper language server for Compose. You can try it out by setting docker.enableDockerComposeLanguageService to true.

It's not very complete though, the completions right now are limited to just help with volumes. We're working on getting more for the next release.

Thanks for info @bwateratmsft . I checked out the readme at https://github.com/microsoft/vscode-docker#docker-compose, had a impression that it is working, but not for me in my vscode.

🤦‍♂️

Somehow we forgot to update the readme! I feel silly...

UPDATE: I opened #3224 for that.

Even if I set docker.enableDockerComposeLanguageService to true it did not work for me. I had to downgrade to version v1.15.0 (random choice, it could be working with next releases inferior to v1.17.0) to get it to work. VS Code version: 1.60.2

The functionality present in 1.17 for the language service is fairly limited; we're working on adding back a lot more in 1.18.

For other users looking to use rollback to a previous version:

[bwateratmsft]

This fix is now released in Docker extension version 1.18.0. The Compose language service has been enabled by default and most of the completions present in 1.16 have returned. Some are not there (especially older Compose spec v2 ones), but we think the most important ones are present.
