LXC updates in Proxmox aren't hard — managing 20 of them at scale is another story

Managing updates across 20+ LXC containers in Proxmox manually is time-consuming. A custom bash script can iterate through all containers, start stopped ones, run apt update/upgrade/autoremove, and shut them back down — reducing hours of work to a single command. For more control, the PVE Community Scripts LXC Updater lets you skip specific containers interactively. For full automation, an Ansible playbook using the community.proxmox collection can create a dynamic inventory of LXCs and run updates without needing SSH access inside each container, and can be extended to Docker, Podman, and VMs.
