This commit refactors the code to remove more or less
all occurences of logrus.Fatalf() from the code under
pkg/ except for app.go where all the errors are being
handled currently.
This is being done since random logrus.Fatalf() calls
all around the code was making handling the errors,
unit testing and troubleshooting a bit more painful.
logrus.Fatalf() calls are either replaced by
return errors.New("new error")
or
return errors.Wrap(err, "annonate error")
calls, and the function signatures are accordingly
changed to accomodate the new return values.
The unit tests which previously used to check
if logrus.Fatalf() calls worked fine have also
been fixed to only check for errors now.
Fixes#416
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.
This adds support for supplying for example:
"127.0.0.1:80:80/tcp" to docker-compose.yaml and converting it to it's
corresponding Kubernetes / OpenShift hostIP.
This commit also refactors the loadPorts function of compose.go
Closes https://github.com/kubernetes-incubator/kompose/issues/335
Moved label handling code from Transformer to loader,
to make it generic to handle creating service types.
Added new attribute to ServiceConfig which gets populated
in loader.
Fixes#273
