Lxc mount mapping

This script computes the mappings to be set in a proxmox lxc container configuration file.

Script setup

To compute the mappings, set the uid_map and gid_map variables of the script. Each entry of these array is organized as follows:

[container_id, host_id]

Output usage

The output is split in 3 parts:

1. Lxc configuration file settings: copy all the lines at the end of the file stored in /etc/pve/lxc/<lxc_id>.conf.

2. subuid configuration file The provided lines should be added at the end of /etc/subuid

3. subgid configuration file The provided lines should be added at the end of /etc/subgid

Directory mapping

Directory mapping can be set up adding the following line in the configuration:

mp0: <host_directory>,mp=<container_directory>,replicate=0

Make sure that the user/group mapped to the cotainer is the owener of the host folder / have the correct access permissions on the folder.
