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`.
This changes allow to use kaniko-warmer multiple times without unnecessary docker image downloads.
To check image presence in cache directory I'm using existing cache function that is used by kaniko-executor.
I've considered building separate function to only check image presence, but it will have pretty much the same code.
Questionable decision is to embed CacheOptions type to KanikoOptions and WarmerOptions. Probably this should be resolved by creating interface providing needed options and implement it both mentioned structs. But I've struggled to get a meaningfull name to it.
To replicate previous behaviour of downloading regardless of cache state I've added --force(-f) option.
This changes provides crucial speed-up when downloading images from remote registry is slow.
Closes#722
When a Dockerfile command requires using the TakeSnapshotFS function,
the resulting layer has a random ordering of files. This causes the
layer to have a non-deterministic hash defeating the reproducible flag.
Issue #710 appears to document this issue as well.
To fix, always sort the list of files to be added in scanFullFilesystem.
This avoids trying to sort the file list during execution, and takes
almost no time to complete.
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
* Revert "Change cache key calculation to be more reproducible. (#525)"
This reverts commit 1ffae47fdd.
* Add logging of composition key back
* Do not include build args in cache key
This should be save, given that the commands will have the args included
when the cache key gets built.
This flag, when set, takes a file in the container and writes the image digest to it. This can be used to extract the exact digest of the built image by surrounding tooling without having to parse the logs from Kaniko, for example by pointing the file to a mounted volume or to a file used durint exit status, such as with Kubernetes' [Termination message policy](https://kubernetes.io/docs/tasks/debug-application-cluster/determine-reason-pod-failure/)]
When the flag is not set, the digest is not written to file and the executor behaves as before. The digest is also written to file in case of a tarball or a `--no-push`.
Closes#654
