This hook runs only when the runtime image reference changes. Use it for setup that is lost when the container image changes, such as packages installed into non-persisted system paths.

​
File path

Create this file: 
/home/node/.agent37/hooks/post-image-update.sh

​
When to use it

This hook is useful when you want to:
  • reinstall system packages
  • restore tools that are not part of your persisted home directory
  • rerun one-time setup after a runtime update

​
Timeout

15 minutes
If the hook fails or times out, startup continues. The image ref is not marked as completed, so the hook retries on the next container start.

​
Example

#!/usr/bin/env bash
set -euo pipefail

sudo apt-get update
sudo apt-get install -y --no-install-recommends ffmpeg
