video from lecture " OPA in Kubernetes" is duplication of OPA Gatekeeper in Kubernetes
I’ll report this to the team. The good news is that the repeated lecture is the one you want – this is a brand new lecture on Gatekeeper, which is the “modern” approach to using OPA in Kubernetes. The old lecture (which appears to have been removed) showed an older approach which put the Rego code into configmaps; this is a very obsolete approach, and no longer recommended.
Update: this is now fixed.
