Get rid of all route related config settings?

[clemensutschig]

Describe the bug
Why do we need people to set route hosts/URLs in env configs for ods resources.

As we seed the resources.. we can always find the host/url combos thru 'oc get' ... and at least via 'oc create route' there is no need to Pass a Host.

You want to remove the config from the configuration-sample/ods-core.env.sample file so that people do not need to configure it?

That would not easily be possible as those values are used as parameters for the templates. When doing template processing, we do not run oc get / oc create.

Or did you mean something else?

Well .. i assume that removing the host part from the Route Templates would force ocp to generate.. ? Worth a try- would simplify a Lot..

[michaelsauter]

Many places also use the URL outside of the Route resource, e.g. as environment variable in the Jenkins pod. All those places would need a "preprocessing step" to fetch the URL. I am not sure this is worth the effort/complexity. I'm going to label this as a question and will remove it from the 3.0 release for now.

[michaelsauter]

As a note to posterity: sometimes the services might run outside of OpenShift (e.g. one can host Nexus elsewhere). In that case, users need to define where Nexus is, and that information cannot be automatically collected.

I'm leaving this open as it is something to think about, but might not be resolved anytime soon.

ok - I tried it finally

apiVersion: v1
kind: Template
objects:
- apiVersion: v1
  kind: Route
  metadata:
    labels:
      app: test-route
    name: test-route
  spec:
    port:
      targetPort: 9000-tcp
    tls:
      insecureEdgeTerminationPolicy: Redirect
      termination: edge
    to:
      kind: Service
      name: sonarqube
      weight: 100
    wildcardPolicy: None

tailor apply

utschig@WKS0000627058 MINGW64 /c/Temp/routet
$ oc get route/test-route -ojsonpath='{.spec.host}'
test-route-odsst-cd.*somehost* 

so this works super nicely - and would allow us to go completely route-less in the config ...

[michaelsauter]

This only works if you leave out host completely. Further, you get drift when you compare again, which should not happen. One can get around this by adding preserve route:/spec/host.

But even then - please see my comment above. Services might run outside of OpenShift. I believe we do need to configure the routes in the config ...
