update stage code so that when comparing the BaseName of
a stage against the recorded, lowercase version of a Stage name
the BaseName is also lowercased.
The third library moby/buildkit lowers the image alias used in 'FROM .. AS' instruction.
This change fixes this issue by making the resolve of dependencies agnostic to case.
Fixes#592Fixes#770
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.
This PR adds support for the dockerignore file. Previously when kaniko
had support for the dockerignore file, kaniko first went through the
build context and deleted files that were meant to be ignored. This
resulted in a really bad bug where files in user mounted volumes would
be deleted (my bad).
This time around, instead of modifying the build context at all, kaniko
will check if a file should be excluded when executing ADD/COPY
commands. If a file should be excluded (based on the .dockerignore) it
won't be copied over from the buildcontext and shouldn't end up in the
final image.
I also added a .dockerignore file and Dockerfile as an integration test,
which should fail if the dockerignore is not being processed correctly or if files aren't being excluded correctly.
Also, I removed all the integration testing from the previous version of the
dockerignore support.
Right now kaniko only supports COPY --from=<another stage>.
This commit adds support for the case where the referenced image is a remote image
in a registry that has not been used as a stage yet in the build.
* 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
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 (!)
gometalinter is broken @ HEAD, and I looked into why that was. During
that process, I remembered that we took the linting scripts from
skaffold, and found that in skaffold gometalinter was replaced with
GolangCI-Lint:
https://github.com/GoogleContainerTools/skaffold/pull/619
The change made linting in skaffold faster, so I figured instead of
fixing gometalinter it made more sense to remove it and replace it with
GolangCI-Lint for kaniko as well.
I added a KanikoStage to hold each stage of the Dockerfile along with
information about each stage that would be useful later on.
The new KanikoStage type holds the stage itself, along with some
additional information:
1. FinalStage -- whether the current stage is the final stage
2. BaseImageStoredLocally/BaseImageIndex -- whether the base image for
this stage is stored locally, and if so what the index of the base image
is
3. SaveStage -- whether this stage needs to be saved for use in a future
stage
This is the first part of a larger refactor for building stages, which
will later make it easier to add layer caching.
This change should fix the bug in #294, where kaniko wasn't recognizing
that a stage would be used in a later build and so wasn't saving it as a
tarball.
Each stage of the Dockerfile has a Name and a BaseName (FROM BaseName as
Name), but if a Name isn't specified then it's set to the same value as
BaseName. Our test cases weren't complete enough to catch this
distinction, which is why this bug occurred.
I added more test cases to the unit tests to make sure this fix works.
* adding reproducible test
* newer version of go-containerregistry
* new ImageOptions
* switch reproducible flag to default to false
* small fixes
* update dep
