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?
This can be done as well
In your docker-composer.yml
user: $DOCKER_USER
In the command line
echo 'export DOCKER_USER="$(id -u):$(id -g)"' >> ~/.bash_profile
source ~/.bash_profile
docker-compose up
Created a DOCKER_USER variable and added it in the bash_profile for persistency. The source will help the shell to recognize changes of .bash_profile on demand
