How to know docker container Id from a devcontainer ( docker-outside-of-docker )?

[ThePlenkov]

Hi!

I have a script building a docker image and running it with the volume attached to a devcontainer.

Something like this:

docker run  --volumes-from $HOSTNAME ...

So this $HOSTNAME contained the id of the devcontainer container id - which is very convenient.

However, when I have switched network mode for my devcontainer ( on purpose ) HOSTNAME became just docker-desktop.

This is not very convenient.

That's how I have thought - can't we have a dedicated variable ( also ok if it's filled from template variable in devcontainer.json ) keeping the actual container id it's running in currently.

What do you think of this>?

Thanks!

Using docker-outside-of-docker you could look up the container based on the labels it has. There are a few labels specific to dev containers depending on how you create the container (e.g., devcontainer.local_folder and devcontainer.config_file).
