How to set uid and gid in Docker Compose?

I can execute a docker run command as such ...

docker run --rm  --user $(id -u):$(id -g) -e MYDATA=/some/path/to/data -e USER=$USER -p 8883-8887:8883-8887 ...

However, in Docker Compose, when I write out the following ...

version: '3.7'
services:
  container_name: some-server
  image: some:img
  user: $(id -u):$(id -g) 
  ...

... it does not work.

I understand I am asking docker-compose up to perform sub shell command substitution, and it cannot.

Is there any way to do this?

Solution

  • Try this

    So, you need to put:

    user: "${UID}:${GID}"

    in your docker compose and provide UID and GID as docker-compose parameter

    UID=${UID} GID=${GID} docker-compose up

    (or define UID and GID as environment variables).
