Docker volumes in docker compose not working

[dct0]

Basic Information

I want to be able to specify docker volumes in a docker compose and run docker compose up in a dev container to start everything up. The bind mounts don't seem to work in this case, and it's likely something to do with the docker-in-docker situation.

Or maybe the LOCAL_WORKSPACE_FOLDER env...

do you have steps of replication?

when you run docker compose, it uses the path of the host, isn't it? That other notes seems interesting though

[frinzekt]

yeah you maybe are right with the local workspace folder env set in https://github.com/codersforcauses/automated-setups/blob/main/cfc-devenv-base/.devcontainer/devcontainer.json

There ended up being (not really) a bug with docker desktop for mac which made it so the bind mounts didn't work microsoft/vscode-remote-release#5388 (comment) in the docker compose. The solution was to use the LOCAL_WORKSPACE_FOLDER env var so I'm thinking it can also be applied to other containers so the bind mounts work properly https://github.com/codersforcauses/django-nextjs-template/blob/main/docker-compose.yml#L6 . Then we can dockerise the entire app which makes running stuff much easier

Are you proposing to use django app dockerised and running in another container?

I'm not opposed to it, but there's a couple of advantages to running django in the devcontainer rather than in another container. Some of the advantages i see are:

• debugger is directly integrated to the IDE (yes, I would like CFC volunteers to learn how to use debugger of the IDE)
• the terminal you use to do migrate, and run scripts is the devcontainer with the shell setup

Can confirm I was able to dockerise entire apps with the env var, so I'm closing this issue
