Modernized Hello-World APB #3

Closed djzager closed 6 years ago

djzager commented 6 years ago

I'm playing around/investigating with a "modernized" APB example. The end goal is to have something showing off openshift_raw and k8s_raw as well as a functioning test playbook. Right now though I've restructured this APB into a single role and wanted to get feedback before moving any further.

Example runthrough with multiple provisions in same namespace:

@djzager I'm liking the simplified structure!

Here's an idea of what it could look like to add per-container config-roles (aka container-enabled) to the APB: https://github.com/djzager/Hello-World-APB/pull/1

LorbusChris commented 6 years ago

Maybe the container name shouldn't be the same as the pod's name, in case there's multiple containers deployed to the pod and we want to easily differentiate them?

dymurray commented 6 years ago

Any ideas why deprovision is failing?

jwmatthews commented 6 years ago

@djzager what are next steps with this PR?

djzager commented 6 years ago

@jwmatthews The next steps are:

  1. Figure out what to do with the test playbook. If you look at the mariadb-apb HA PR, specifically the test playbook there are some good things going on there that we should investigate. It goes beyond the typical "verifications" that I've seen in other test playbooks and actually interacts with the database as a test. It's also a little complex. I want to be sure that test playbooks are supported by any apb-test-shim we develop. There may be nothing more to do here as the apb-test-shim already runs the test playbook if it exists in the project.
  2. Talk with @dymurray and make sure that what I'm doing here lines up with the ansible-galaxy integration.
  3. Move the apb-test-shim project under one of our organizations.
djzager commented 6 years ago

I'm using this PR to test the changes in --> https://github.com/ansibleplaybookbundle/apb-test-shim/pull/4 In the end this will rely on that PR being merged.

djzager commented 6 years ago

@fabianvf + @dymurray I think this is ready to go

djzager commented 6 years ago

Updated the example to use lookups based on @fabianvf request. Now this is blocked by https://github.com/ansible/ansible/pull/37533 ... once that is merged I'll make sure everything is good to go and get :+1: again.

djzager commented 6 years ago

Putting this here for when I forget. The kubernetes latest is going to fail because of https://github.com/kubernetes/minikube/issues/2629
