* Extend .dockerignore integration test with copies in later stages
.dockerignore should continue to apply when copying from the build context in later stages, but it currently doesn't
* Replace excluded global with passed along FileContext struct
This new FileContext struct allows much cleaner handling of context specific file exclusions.
The global excluded file state is no longer needed.
Additionally this also fixes the issue where excluded files aren't being applied for build context copies in later build stages.
Cached COPY layers are expensive in that they both need to be retrieved
over the network and occupy space in the layer cache.
They are unnecessary in that we already have all resources needed to
execute the COPY locally, and doing so is a trivial file-system
operation. This is in contrast to RUN layers, which can do
arbitrary and unbounded work.
The end result is that cached COPY commands were more expensive when
cached, not less. Remove them.
Resolves#1357
* 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
This change calculates the exact files and directories needed between
stages used in the COPY command. Instead of saving the entire
stage as a tarball, we now save only the necessary files.
We previously had an optimization that would skip snapshotting mutli-stage images
when in an intermediate stage, until the very end.
This conflicted with another optimization to avoid snapshotting when no files had changed.
* parse arg commands at the top of dockerfiles
* fix pointer reference bug and remove debugging
* fixing tests
* account for meta args with no value
* don't take fs snapshot if / is the only changed path
* move metaArgs inside KanikoStage
* removing unused property
* check for any directory instead of just /
* remove unnecessary check
As mentioned in #346, if only ENTRYPOINT is set in a stage then any
CMD inherited from a parent should be cleared.
If both entrypoint and cmd are set then nothing should change.
I added a function and unit test to review the config file after building a stage
which clears out config.Cmd if ENTRYPOINT was declared but CMD wasn't.
I also added an integration test to make sure this works, which should
be tested by the preexisting container-diff --metadata test.
