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.
In this refactor I:
1. Created KanikoOptions to make it easier to pass around arguments
passed in through the command line
2. Reorganized executor.go by putting the logic for pushing the image in
a new file push.go
3. Made some error messages clearer
4. Fixed a mistake in the README for pushing to AWS
5. Marked the --bucket flag as hidden since we want people to use
--context instead, and marked an aws flag as hidden which is set in a
vendored directorya
