Synchronise the documented Operator SDK version.

Makefile:265 selects v1.42.3, but doc/overviews/development.md:5 declares v1.32.0 as required. Update the guide, or state explicitly that v1.32.0 is the supported minimum.

In `@Makefile` at line 265, Synchronize the Operator SDK version between the
Makefile setting OPERATOR_SDK_VERSION and the development guide: either update
the guide to reflect v1.42.3 or explicitly document v1.32.0 as the supported
minimum, while keeping the version requirements unambiguous.

Curious, is there anything specific we need from these new Operator SDK versions, or just a good time to do a bump?

@jjkiely, I found no evidence that the default-deny NetworkPolicy needs Operator SDK v1.42.3.

The PR has one commit, and its message only describes the network policy. The SDK-related changes update the configured SDK version and generated bundle builder annotations. The CSV also gets a new createdAt value. This is consistent with regenerating the bundle using a newer local toolchain.

So this looks like a routine SDK bump, not a functional dependency. The PR author should confirm the intended reason. The documentation should still state the selected version, or clearly define the supported minimum.

@jjkiely, sorry. I misunderstood the conversation and replied when you were addressing Jim. I will not add further analysis to this thread.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Do not release the deny policy before the allow policies.

The policy selects every pod and provides no ingress allow rule. Applying it before the dependent policies are available will deny required pod-to-pod traffic. (kubernetes.io)

  • config/default/deny-all.yaml#L6-L8: keep the base policy gated until PR #2195 and PR #1 are available.
  • config/default/kustomization.yaml#L47-L47: ensure the direct-install output includes the allow policies before this resource is applied.
  • charts/kuadrant-operator/templates/manifests.yaml#L15150-L15152: render the allow policies with the Helm chart before publishing it.
  • bundle/manifests/kuadrant-operator-default-deny-all_networking.k8s.io_v1_networkpolicy.yaml#L8-L10: publish the bundle only after its required allow policies are available.
