--cache-from=image

Repository to utilize as a potential cache source. When specified, Buildah tries to look for cache images in the specified repository and attempts to pull cache images instead of actually executing the build steps locally. Buildah only attempts to pull previously cached images if they are considered as valid cache hits.

Use the --cache-to option to populate a remote repository with cache content.

Example

# populate a cache and also consult it
buildah build -t test --layers --cache-to registry/myrepo/cache --cache-from registry/myrepo/cache .

Note: --cache-from option is ignored unless --layers is specified.
