I have a host running several containers:
- A Nginx reverse proxy
- Gitlab CE
I also mounted a network share by adding this line to my /etc/fstab:
//mycompany/sharedfolder /mnt/sharedfolder cifs credentials=/root/.smbcredentials,users,rw,iocharset=utf8,sec=ntlm,vers=3.0 0 0
As root, from my machine, I can read and write on this /mnt/sharedfolder
In my docker-compose.yml entry for gitlab-runner, I added this new volume (last line):
gitlab-runner: image: gitlab/gitlab-runner:latest container_name: gitlab-runner hostname: gitlab-runner restart: always volumes: - '/srv/gitlab-runner/config:/etc/gitlab-runner' - '/var/run/docker.sock:/var/run/docker.sock' - '/mnt/sharedfolder:/mnt/sharedfolder:rw'
But when I run a job with my runner, I don’t have the permissions to write on /mnt/sharedfolder, only to read.
$ touch /mnt/sharedfolder/test.txt touch: cannot touch '/mnt/sharedfolder/test.txt': Permission denied
I’m now completely lost with permissions and who’s executing what… Any enlightening suggestions ?
Thanks a lot
