[moficodes]

In the source yaml https://github.com/GoogleContainerTools/skaffold/blob/master/examples/microservices/leeroy-web/kubernetes/deployment.yaml the yaml file changed and removed the first yaml doc for service.
this change makes the tutorial fail. removing reference to yqArg since deployment.yaml has only one document now.

Hi @moficodes. Thanks for your PR.

I'm waiting for a tektoncd 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.

Oh dang, that's unfortunate. I wonder if we should create our own demo application to use in examples instead.

Whoops thanks for catching that @moficodes !

It looks like we ran into this in our examples dir also and our solution was to always checkout the source at 0.32.0 🤔
