proxmox_scripts

Set of Proxmox scripts that can be useful for anyone.

Tested on Proxmox VE 8.

Run a command in all nodes

Needs jq. Install with apt update && apt install -y jq

Write the following script into a file name cssh:

#!/bin/bash
if [ ! -n "$1" ]; then echo "Usage: $0 [command]"; else
  for n in $(cat /etc/pve/.members  | jq -r '.nodelist[].ip'); do
    echo --- $n -----------------------------------------------------
    ssh -T $n "$@"
  done
fi

Example output:

root@proxmox-1:~# chmod ./cssh
root@proxmox-1:~# ./cssh cat /etc/debian_version

lxc_create_github_actions_runner.sh

Creates and sets up a self-hosted GitHub Actions runner in an LXC container on Proxmox:

Create a new LXC container based on ubuntu 23.04
Installs apt-get dependencies (git, curl)
Installs docker
Installs Github actions (needs GITHUB_TOKEN and OWNERREPO) and sets up service

NOTE: Since the new container has docker support, it cannot be run unpriviledged. This approach is more insecure than using a full-blown VM, at the benefit of being much faster most times. That being said, make sure you only use this self-hosted runner in contexts that you can control at all times (e.g. careful using with public repositories).
