Allow developers to select individual services in docker-compose.yml (or specific docker compose file) to launch

[ben-xD]

As per the documentation (Use Docker Compose). This is useful to declare configuration passed to docker run in a widely supported format - this is much better than configuring them inside .devcontainer/devcontainers.json's runArgs which is only read by this extension.

However, to make the experience even better, a developer might want to configure different runArgs for different scenarios. In one configuration, they might want to pass --gpus=all, and the other case, the container shouldn't be given any GPUs. Currently, the developer has to either

• manually edit the devcontainer.json file
• use docker compose inside devcontainer.json, and have 2 or more docker-compose files. They would have to switch between files to change the configuration.

It would be great

• if we choose from a menu, which service we want to launch after declaring them services in a docker-compose.yml file with these different configurations, or
• if we can choose from a menu of docker compose files (We would have to declare it up front in the devcontainers.json file.), where each docker compose contains different sets of services
  • This is the more general purpose one: Developers might have 2 or 3 services in one docker-compose.yml, and might want to configure them differently.
