Using on docker-compose containers?

[dabro]

How would you suggest best using or modifying this package to use containers that are managed by docker-compose, which move a lot of configuration/env/dependency settings to the docker-compose.yml file? There is of course docker-compose exec, whose big difference is the lack of -e and the default tty allocation. But you also have to account for the docker-compose options, like -p to specify a non-default docker-compose.yml file, and the difference between the docker name (eg dev_box_1) and the docker-compose service name (eg box):

Execute a command in a running container

Usage: exec [options] SERVICE COMMAND [ARGS...]

Options:
    -d                Detached mode: Run command in the background.
    --privileged      Give extended privileges to the process.
    -u, --user USER   Run the command as this user.
    -T                Disable pseudo-tty allocation. By default `docker-compose exec`
                      allocates a TTY.
    --index=index     index of the container if there are multiple
                      instances of a service [default: 1]

There's also docker-compose run:

Run a one-off command on a service.

For example:

    $ docker-compose run web python manage.py shell

By default, linked services will be started, unless they are already
running. If you do not want to start linked services, use
`docker-compose run --no-deps SERVICE COMMAND [ARGS...]`.

Usage: run [options] [-v VOLUME...] [-p PORT...] [-e KEY=VAL...] SERVICE [COMMAND] [ARGS...]

Options:
    -d                    Detached mode: Run container in the background, print
                          new container name.
    --name NAME           Assign a name to the container
    --entrypoint CMD      Override the entrypoint of the image.
    -e KEY=VAL            Set an environment variable (can be used multiple times)
    -u, --user=""         Run as specified username or uid
    --no-deps             Don't start linked services.
    --rm                  Remove container after run. Ignored in detached mode.
    -p, --publish=[]      Publish a container's port(s) to the host
    --service-ports       Run command with the service's ports enabled and mapped
                          to the host.
    -v, --volume=[]       Bind mount a volume (default [])
    -T                    Disable pseudo-tty allocation. By default `docker-compose run`
                          allocates a TTY.
    -w, --workdir=""      Working directory inside the container

What problem do you have with docker-compose? I am already using this library for the containers managed by compose, and it works just fine

Maybe the confusion here is between the service name and the container name (as mentioned box vs dev_box_1). However this is not a problem and the package works no problem so long as the container name is used.

It would be nice to maybe map to the service name but then I call everything app so that would likely result in more confusion than good.

If you always want names (rather than the container IDs) to appear in the completion list then (setq docker-tramp-use-names t)
