Description

Hi I am using the below configuration in my github actions:

    - name: Build and cache
      uses: docker/build-push-action@v4
      with:
        context: .
        push: true
        tags: localhost:5000/my-app/app:latest
        cache-from: type=gha
        cache-to: type=gha,mode=min

Its working as expected, the first run it builds my Dockerfile and the second run it uses the cache. However I have noticed that after 1 day or so the cache is not used anymore and needs to run the build again.

I read the ttl for cache entries on github action is 1 week https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#usage-limits-and-eviction-policy. Is there some setting I need to use to specify the ttl?

Thanks

Expected behaviour

Cache is re-used.

Actual behaviour

Cache is not re-used after about 1 day.

I don't think there is a way to set a custom TTL with current GitHub API atm.
