I improved handling of the .dockerignore file by:
1. Using docker's parser to parse the .dockerignore and using their
helper functions to determine if a file should be deleted
2. Copying the Dockerfile we are building to /kaniko/Dockerfile so that
if the Dockerfile is specified in .dockerignore it won't be deleted, and
if it is specified in the .dockerignore it won't end up in the final
image
3. I also improved the integration test to create a temp directory with
files to ignore, and updated the .dockerignore to include exclusions (!)
Updated README to clarify:
1. What a build context is and how kaniko interacts with it
2. How to set up a Kubernetes secret for auth to push the final image
Also made some general fixes to make the docs and the run_in_docker
script more clearer.
Issue #410 experienced an error with base image caching where they were
"Not Authorized" to get information for a remote image, but later were
able to download and extract the base image.
To fix this, we can switch to using the remoteImage function for getting
information about the digest, which is the same function used for
downloading base images. This way we can also take advantage of the
--insecure and --skip-tls-verify flags if users pass those in when
trying to get digests for the cache as well.
It seems like .dockerignore deletes files containeed within the file locally upon
docker build, so I created a temporary test dir to make sure the
--ignore flag works. We make sure it exists before building docker and
kaniko for Dockerfile_test_ignore, and then delete it after the builds
have completed.
Added a --ignore flag to ignore packages and files in the build context.
This should mimic the .dockerignore file. Before starting the build, we
go through and delete ignored files from the build context.
* comments
* initial commit for persisent volume caching
* cache warmer works
* general cleanup
* adding some debugging
* adding missing files
* Fixing up cache retrieval and cleanup
* fix tests
* removing auth since we only cache public images
* simplifying the caching logic
* fixing logic
* adding volume cache to integration tests. remove auth from cache warmer image.
* add building warmer to integration-test
* move sample yaml files to examples dir
* small test fix
This change refactors the build loop a bit to make cache optimization easier in the future. Some notable changes:
The special casing around volume snapshots is removed. Every volume is added to the snapshotFiles list for every command that will snapshot anyway.
Snapshot saving was extracted to a sub-function
The decision on whether or not to snapshot was extracted
* Rework cache key generation a bit.
Cache keys are now based on the previous commands, rather than the previous state
of the filesystem.
* Refactor command interface a bit, only cache the context for commands that use it.
