Manage user account with Docker
I love how Docker is managing volume, port and networking.
But I found Docker is missing something to manage properly user (hence file / volume permission).
Use case:
"with GitlabCI, run as user
gitlab, we use gradle Docker image to
build application"
(https://hub.docker.com/_/gradle/ that declare properly the user gradle).
This image will create jar files, owned by gradle user, hence user gitlab cannot clean these files => break GitlabCI.
If I run Docker with --user=$UID , files are ok, but since gitlab is not a valid user inside the Docker gradle image, some Java unit tests failed (Java security stuff).
My solution was to create user inside the Docker image:
#!/bin/sh
BUILD_CMD="gradle build"
set -eux
if test -n "$USER_UID" && test -n "$USER_NAME"; then
adduser --uid $USER_UID --quiet --home /home/gradle --disabled-password --gecos "djobi" $USER_NAME
exec su -c "$BUILD_CMD" $USER_NAME
else
exec $BUILD_CMD
fi
This is working fine, I am wondering if there is a better solution, more global, to affect ALL running containers of my docker-compose.yml ?
