Moves the version information to a seperate file. This is mostly due to
import cycle errors occuring when using "import
github.com/kubernetes/kompose/cmd" in order to get the global variable
of VERSION and GITCOMMIT.
Update's the Makefile and other files accordingly.
If the version and commmit is unretriveable due to not being able to
find the kompose binary, the one from pkg/version/version.go will be
used.
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).
Closes#239#253
