Fix unable to start container process: unable to apply caps: operation not permitted: unknown in Docker

/ January 22, 2023/ Docker

While trying to run a docker-compose with a Frigate container inside an LXC container (in Proxmox) I had this problem and finally found the solution.

The problem appears because the recommended docs of Frigate show a docker-compose.yml that declares that container as privileged: true but we are already in a privileged mode so that is not needed.

Removing privileged: true fixed the Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: unable to apply caps: operation not permitted: unknown problem.
