We can find references to our deprecated APIs in at least two places
- In the k8s yaml that we apply using helmfile and helm These can be found by searching through the output of helmfile -q -e <production/staging> template (e.g. | grep -B 10 extensions/v1beta1)
- in applications that talk to the kubernetes api This is possible to see using the "recommendations" feature of GKE (https://cloud.google.com/kubernetes-engine/docs/deprecations/viewing-deprecation-insights-and-recommendations#view-deprecation-insights-recs)
- - our internal charts
- - wikibase-ingress
- stable charts
- - nginx-ingress-controller
- kubernetes-client
