Content Refresh (3.x to 4.7)

v3 content migration progress

This issue has been created to track progress and feedback related to deprecation of our OpenShift v3 course content

We're hoping to update or remove all affected scenarios over the next few weeks.

Q: Why is this change urgent? A: See openshift/openshift-ansible#12288

Learning scenarios that are listed here will need to be updated to use openshift-4-7 as the backend.imageidsetting in your index.json file.

If your scenario is listed above, try testing your content using openshift-4-7. If you are able to successfully migrate to v4, let me know, and I'll help promote the refreshed content.

If you need extra help, or if you discover that our OpenShift v4 images do not include some CLI utilities you require, add a note here: https://github.com/openshift-labs/learn-katacoda/issues/1061

[jamesfalkner]

@ryanj I've updated Java EE 8 Development to use openshift-4-6 (and other updates). Wasn't sure if I should start using openshift-4-7 yet as I don't other scenarios using it. Also set it to autoUpdate: true.

[ryanj]

@jamesfalkner I just removed the openshift-4-6 playground and am working on deprecating that image. I'd swap to openshfit-4-7

https://github.com/openshift-labs/learn-katacoda/pull/1178 starts the long-planned process to remove istio in favor of service mesh scenarios.

This removes all old Istio scenarios and lays a base foundation for the migration of the content from https://github.com/thoraxe/lab-ossm

Right now the first scenario is almost ready to go.

Acknowledged, thanks. Checked off the box.

[dewan-ahmed]

@jdob @ryanj it gives me immense pleasure to check-off the final box for Spring list. Now we eagerly await for https://github.com/openshift-labs/learn-katacoda/issues/1061 to resolve.
