Add unit tests that check the behaviour of CompositeCache
on adding filesytem resources. It checks that
* 2 identical directory trees produces the same hash
* an extra file produces a different hash
* an extra directry produces a different hash
* an extra file that is excluded does not alter the hash
* an extra directory that is excluded does not alter the hash
Previously kaniko would compute the cache key for any copy command by computing
the combined hash of all files in a directory, even if they were listed
as ignored.
With this change, the cache key creation was updated to be aware of ignored
files.
Related issues:
* https://github.com/GoogleContainerTools/kaniko/issues/594
* Update cached copy command to return the same result for
files used from context so that cached and uncached copy
commands produce the same cache key
* Update tests for fix
* Add test for cached run command key consistency
* use the cachekey of the src stage rather than the digest
for COPY --from commands as they are reproducible unlike digests
* track digest to cache keys and stage indexes to digest
* add extra debug logging for troubleshooting cachekey building issues
* convert Sha256 hashes to hex encoded strings rather than plain strings
for easier human reading
Store the last cachekey generated for each stage
If the base image for a stage is present in the map of digest
and cachekeys use the retrieved cachekey instead of the base image
digest in the compositecache
Fixed#296.
The output manifests may have `application/vnd.docker.distribution.manifest.v2+json`
as their media types instead of `application/vnd.oci.image.manifest.v1+json`.
Resolves#607
* Deleted a duplicate Gopkg.lock block for github.com/otiai10/copy to
prevent `dep ensure` from deleting it from vendor/
* Searched for breaking changes. Only found ones for
remote.Delete/List/Write/WriteIndex. Searched for those and fixed
* Noticed that NewInsecureRegistry was deprecated and replaced it
