Caching in CI/CD environments?

[rcowsill]

Many CI/CD systems run builds in a fresh environment every time. That means there are no cached layers present, so container image builds start from scratch each time.

Docker has a few ways to inject layers into the build cache: the --cache-from option and docker save/docker load. These make it possible to export docker's build cache into the CI/CD system's cache and then restore it for later builds.

Is there any way to do that in podman? It seems that --cache-from is a no-op and podman load doesn't add the loaded layers to the cache.
