kubernetes or openshift does not allow underscores in the object
names, while docker-compose does, in this commit the code has been
added to convert underscores to hypens.
There's A LOT happening in this commit, so here's an outline:
First off, urfave/cli has been removed in favour of spf13/cobra. With
this, comes changes to the formatting as well as the help page for
Kompose.
Upon converting, I noticed a CLI flag was NOT appearing for OpenShift.
Specifically, --deploymentconfig. This has been added with a note
that says it is OpenShift only.
Exit codes have been fixed. If the conversion / down / up fails for
any reason, Kompose will exit with Code 1.
--verbose as well as --suppress-warnings can now be set at the
same time.
app_test.go in the cli directory has been moved to pkg/transformer
to better reflect the testing coverage.
version.go has been removed and converted to it's own CLI command in
conjuction with (most) Go software. A new CLI command has been
created. kompose version
--dab isn't a conventional way for short-form CLI paramters. This
has been shortened to -b for bundle.
CLI flags consisting of only two/three letters have been removed due to
it being unconventional for CLI. For example, --dc was removed in preference
for --deploymentconfig
--replicas has been added as an option when using kompose down or
kompose up. This has been added as previously in app.go the
replica amount was hard-coded as 1.
Differentiating names have been used for flags. For example,
persistent flags use the name Global (ex. GlobalOut). Command-specific
flags have their own names (ex. UpOpt).
