Cache single file #33
Description
I'm trying to cache the result of docker save, which creates a tar file.
When I try to cache a single file, an error is raised.
- name: Cache docker layers
uses: actions/cache@preview
id: cache
with:
path: docker_cache.tar
key: ${{ runner.os }}-docker
/bin/tar -cz -f /home/runner/work/_temp/9d43813f-9c7b-4799-ac7d-f8d0749e7d8c/cache.tgz -C /home/runner/work/<repo>/<repo>/docker_cache.tar .

/bin/tar: /home/runner/work/<repo>/<repo>/docker_cache.tar: Cannot open: Not a directory

/bin/tar: Error is not recoverable: exiting now

##[warning]The process '/bin/tar' failed with exit code 2
I could create a directory just to hold the tar file, but it would be nice if this actions supports caching single files.
