Execute LXC Pre-shutdown/stop script

[Fathi]

Hi,
I am suspecting postgresql from pgdg yum repo to not stop when lxc container is instructed to stop/shutdown and thus preventing my configured backups to occur.
Is there a way to instrcut proxmox to run a script inside the container (script path relative to the container) before stopping/shutting down the container ?
TIA

PVE issues a "shutdown" to the container, not a hard stop, so you should be able to just add a systemd target (or similar) in your container that runs on "shutdown". Alternatively, look into hookscripts: These are scripts that can be placed on the PVE host and then attached to a container - they'll be run before and after a backup or shutdown, among other points, and you could for example SSH into your container at that point and perform any cleanup actions. See our wiki, docs, and search this forum for more info.
