Types

type Cache

type Cache struct {
	// contains filtered or unexported fields
}

Cache allows us to keep state for repositories, rather than querying them every time.

Cache Structure: <cacheDir>/git/ * Caches bare git repositories in directories named based on the repository address. <cacheDir>/oci/ * Caches oci images with further hierarchy underneath * We Cache image layers in <cacheDir>/oci/layers/ (this might be obsolete with the flattened Cache) * We Cache flattened tar files in <cacheDir>/oci/ (so we don't need to pull to read resources) * We poll the repositories (every minute) and Cache the discovered images in memory.
