Hi @mkimuram. Thanks for your PR.

I'm waiting for a operator-framework or openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

It seems that #563 is doing a similar change, but it has no update for a long time.
I guess that the reason that the PR takes much time to merge would be that the PR includes big changes on other features like multi-stage builds and adding e2e tests to use buildah everywhere, therefore I hope that this PR helps making progress on just supporting buildah.
(Actually, I had a trouble in building operator in my only-buildah-installed environment, so adding this feature early will help me a lot.)

For memcached-operator, builds with below commands succeeded after applying this PR,
in an envrionment where buildah is installed.

$ export IMAGE=quay.io/example-inc/memcached-operator:v0.0.1
$ operator-sdk build --image-builder buildah $IMAGE
$ sed "s@REPLACE_IMAGE@$IMAGE@g" -i deploy/operator.yaml
$ operator-sdk build --image-builder buildah --enable-tests $IMAGE

I like that this uses a flag to tell the build to use buildah and keeps the same default, this allows us to switch the default when it makes sense.

I wonder if there is some way to hide the switch statement in its own function because we have to do it twice? I looked at it, and it might not be super easy but would like to see an attempt.

WDYT?

WDYT of re-using a flag build-args for both docker and buildah?

Can we rename docker-build-args with something like image-build-args?

Then re-using flag makes sense to me. I'm not sure how operator-sdk community thinks about the backward compatibility of command line option.

image-build-args is fine with me. We'll have to add these changes to the CHANGELOG.md too.

I'm fine with these changes overall. A few points need addressing first.

Below error happens without quote for [docker, buildah], so fixed in the last commit.
