Cant precompile assets

Infos:

  • Used Zammad version: 5.0.x
  • Used Zammad installation type: docker-compose
  • Operating system: Ubuntu 20.04.3 LTS
  • Browser + version: Firefox 94.0

I wanna change the colors of admin UI so I added a custom css to /var/lib/docker/volumes/zammad-docker-compose_zammad-data/_data/app/assets/stylesheets/custom/custom.css.
I know that the next step is to compile the assets. Using Portainer, I executed the command rails r rake assets:precompile

Expected behavior:

  • assets should compile

Actual behavior:

Steps to reproduce the behavior:

  • Install zammad using docker-compose
  • execute the command rails r rake assets:precompile on the rails container

Is there any way to precompile assets in docker-compose setup? Thanks
