Cache Anything New in Container | Action

This is a fork of airvzxf/cache-anything-new-action that works in Docker containers.

sudo does not work in Docker containers, so instead run the container as root (with options: --user 0).

This GitHub action scans the container to check if anything new was added after you run a script, then caches all new files.

Usage example

Create your script as .github/workflows/install.sh

#!/bin/bash -e

sudo apt update
sudo apt install -y pandoc
echo "Hello World!" > hello.txt

Add the action in .github/workflows/your_action.yml.

          key: ${{ runner.os }}-cache-hello-world-key-v1.0

      # is_cached: use the previous cache action id.
      # cache: should be the same as the cache 'path'.
      - name: Cache anything
        uses: plu5/cache-anything-new-in-container-action@main
        with:
          script: 'install.sh'
          is_cached: ${{ steps.cache-id.outputs.cache-hit }}
          cache: ${{ runner.temp }}/cache-directory-example
          snapshot: '/'
          exclude: '/boot /data /dev /mnt /proc /run /sys'

      # Optional
      - name: Use the cache
        run: |
          find /home/ -iname hello.txt 2> /dev/null || true
          whereis pandoc || true

The uses: actions/cache is required because it needs this external action to store the cache. This action only finds the new created files and stores them in a temporary directory which is cached by actions/cache.
