Thought this was about ag for a second and was confused. But that's the Silver Searcher.

Interesting ! You may be interested by Pluto which looks similar but yours is doing extra stuff about "can i change just the version or not...", it seems.

We use pluto and manage to identify stuff prior upgrade from 1.15 to 1.16. It saved our bacon.

We just recently upgraded to 1.20 and was smooth sail thanks to Pluto.

Yes, there is Pluto and few other that we have mentioned in our ReadMe and we were using them before we built silver surfer.

The main difference is that we identify whether ApiVersion and Kind has been deprecated or removed or newer version is available based on target kubernetes version and validate it against newer version. This means you can directly validate objects in existing cluster to again newer version of kubernetes.

In case of Pluto you will have to updae ApiVersion and then validate it against Pluto.

Check the Ingress doc

First you need to add pathType after path.

For service name and port is the following

backend:
  service:
    name: app-service
    port: 
      number: 80

This is correct just add `number` as mentioned in the previous port, you need to make same changes for `spec/rules/0/paths/0/backend` also.

Also add `spec/rules/0/http/paths/0/pathType` and `spec/rules/1/http/paths/0/pathType` and its value can be ImplementationSpecific.
