And plugin registry is correct

$ oc get dc/che -o json | grep plugin
   "value": "https://che-plugin-registry.openshift.io/v3"

@benoitf I see that we are not deploying the registries when the installer is the minishift-addon. That makes sense because the minishift addon doesn't deploy them. But that's still an issue: the version of the registries on osio is an outdated one. We need to update the registries on openshift.io. It should be straightforward for the devfile registries, not sure for the plugin registry cc @ibuziuk

[benoitf]

@l0rd yes eclipse-che/che#14138 and openshiftio/saas-openshiftio#1323

Looks like nothing should be broken, so I approved the PR with promotion to prod. It is absolutely needed I'm ok to promote it to production now

@benoitf @ibuziuk fantastic. devfile registry should be updated as well.

both plugin and devfile registries have been updated on prod
