question: how to specify docker compose version?

[sarisia]

Running @devcontainers/ci on GitHub Actions hosted runner ubuntu-22.04 (which has both compose v1 and v2) uses docker compose v1 and building image for compose.yaml (which v1 does not support) fails.

Are there any way to specify docker compose version the action uses?

[stuartleeks]

The action uses the devcontainer CLI for the underlying dev container interactions, so it's probably worth raising an issue on https://github.com/devcontainers/cli to see whether it is possible to control the docker compose version when using the CLI

[sarisia]

devcontainer CLI has --docker-compose-path option and confirmed it's working.

(actions runner ubuntu-latest)

// compose v1
$ devcontainer build --workspace-folder . --docker-compose-path /usr/local/bin/docker-compose

// compose v2
$ devcontainer build --workspace-folder . --docker-compose-path /usr/libexec/docker/cli-plugins/docker-compose

Adding the --docker-compose-path or equivalent options (or, just args for support arbitrary usecases) to the action may help.
