I am running a Bitwarden instance in Kubernetes and want to harden it, because to it contains vital secrets. However, if I try as a start to set:

    spec:
      securityContext:
        runAsUser: 1000
        runAsGroup: 1000
        fsGroup: 1000

I am getting several errors from the entrypoint.sh:

addgroup: Only root may add a user or group to the system.
adduser: Only root may add a user or group to the system.
cp: cannot create regular file '/app/Identity/identity.pfx': Permission denied
cp: cannot create regular file '/app/Sso/identity.pfx': Permission denied

and

[ ... and so on ... ]

This happens due to the entrypoint.sh:

  • creates user and group
  • creates certificates
  • enable/disable services
  • massively chowns directories

Useradd, groupadd could be easily moved in the Dockerfile, as well as the permissions/group ownership. Seems like "Enable/Disable services" also should be rather in the Dockerfile. /etc/bitwarden that is altered by the entrypoint.sh should be a persistent volume, since we want to keep instance identity on restarts, it's not a problem.

/etc/supervisor.d is mostly where systemd stores content. Don't try to outsmart systemd: Rather than using "bitwarden.sh" directly, create a systemd for bitwarden and enable the designated service user to start or stop that, with the escalations built into systemd.
