A quick helm dry run gives me:

  rules:
  - host: "coder.theDomain.io"
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: coderd
            port:
              name: tcp-coderd
  - host: "*.theDomain.io"
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: coderd
            port:
              name: tcp-coderd
  tls:
    - hosts:
      - "code.theDomain.io"
      secretName: "coder-theDomain-io-tls"

In above snippet I would have expected the wildcard tls host entry to get created as well. When I look in Ingress template I found these ambiguities:

Line 40: .Values.coderd.devurlsHost
Line 57: .Values.devurls

Next, in the Docs it is written that one needs to create a seperate ingress manually. An own ingress will most likely conflict. I think this is a Documentation bug/ambiguity and should be adressed.

Next, there is no option to set ingress classname.
