Hey guys,
I tried installing mailcow in a container on my proxmox host today but I got hit with this weird error when trying to start the container.
Error response from daemon:
failed to create task for container:
failed to create shim task:
OCI runtime create failed:
runc create failed:
unable to start container process:
error during container init:
error setting rlimits for ready process:
error setting rlimit type 6:
operation not permitted:
unknown
the error message was one line; added returns for readability
I used the official guide and the package manager route. All docker files seem to have been pulled successfully but docker compose up -d quit, not starting these two services:
⠦ Container mailcowdockerized-postfix-mailcow-1 Starting 32.8s
⠙ Container mailcowdockerized-dovecot-mailcow-1 Starting 32.8s
Upon rerunning the other services reported as Running
Opening journalctl gave me this:
