Ask questionsSupport docker run with --user $(id -u):$(id -g) cli arg (shared process error)

Test environment

Host OS: OSX 10.14.4 Docker: (31259) image: codercom/code-server:1.621



We run docker in a locked down environment where we alias the docker run cli command to prepend --user $(id -u):$(id -g) on all host operating systems. This is a security constraint we can't remove. When i try to execute code server simulating this environment it throws a shared process error. Any ideas on an approach to resolve?

Answer questions ibnesayeed

If I supply -u (or --user) flag to keep file permissions correct as if I were to play with my files on the host, the service is failing to create a ./cache directory. Is it something that can be configured to create under the /tmp instead of the root of the file system?

$ mkdir /tmp/foo
$ cd /tmp/foo
$ docker run --rm -it \
  -u $(id -u):$(id -g) \
  -p \
  -v $PWD:/home/coder/project \
  codercom/code-server --allow-http --no-auth
