AltaNivel 1Automatizadadocker

Descripción

The containerd socket /run/containerd/containerd.sock must have mode 660 or more restrictive so that it cannot be modified by non-root users. The audit flags any existing candidate path (/run/containerd/containerd.sock) with permission bits outside 660; not applicable when none exists.
