LXC Container bind mount: map all uid/gid to a single uid/gid on the host — by McChaos on Proxmox Forum

A solved thread on giving an unprivileged LXC write access to a host folder. The author maps GID 1000 straight through with lxc.idmap, allows it in /etc/subgid, creates a matching datauser group in the container and finally adds root to that group, which was the missing piece.

Quick steps

  1. Add lxc.idmap: g 1000 1000 1 (with surrounding ranges) to the container config
  2. Add root:1000:1 to /etc/subgid on the host
  3. Create a datauser group (GID 1000) in the container and add the users and root to it
