* Add missing improvements from Operator SDK 1.34.1
These were not mentioned in the upgrade documentation for version 1.34.x (https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.34.0/), but I've found them by compating the release with the previous one (https://github.com/operator-framework/operator-sdk/compare/v1.33.0...v1.34.1).
* Upgrade to Operator SDK 1.36.0
Source of upgrade steps: https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.36.0/
Key differences:
- Go packages `k8s.io/*` are already at a version higher than the one in the upgrade.
- `ENVTEST_K8S_VERSION` is at a version higher than the one in the upgrade
- We didn't have the golangci-lint make command before, thus we only needed to add things.
* Upgrade to Operator SDK 1.38.0
Source of upgrade steps: https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.38.0/
* Upgrade to Operator SDK 1.39.0
Source of upgrade steps: https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.39.0/
* Upgrade to Operator SDK 1.40.0
Source of upgrade steps: https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.40.0/
I didn't do the "Add app.kubernetes.io/name label to your manifests" since it seems that we have it already, and it's customized.
* Address lint errors
* Update golangci-lint version used to support Go 1.24
* Improve workflows
- Make workflow targets more specific.
- Make build workflow only build (i.e. remove test part of it).
- Rearrange steps and improve naming for build workflow.
* Add back deleted test
Initially the test has been removed due to lint saying that it was duplicate code, but it falsely errored since the values are different.
* Improve code and add missing upgrade pieces
* Upgrade to Operator SDK 1.41.1
Source of upgrade steps: https://sdk.operatorframework.io/docs/upgrading-sdk-version/v1.41.0/
Upgrading to 1.41.1 from 1.40.0 doesn't have any migration steps.
Key elements:
- Upgrade to golangci-lint v2
- Made the manifests using the updated controller tools
* Address linter errors
golanci-lint v2 seems to be more robust than the previous one, which is beneficial. Thus, we address the linter errors thrown by v2 and improve our code even further.
* Add Makefile improvements
These were brought in by comparing the Makefile of a freshly created operator using the latest operator-sdk with ours.
* Add missing default kustomization for 1.40.0 upgrade
* Bring default kustomization to latest version
This is done by putting the file's content from a newly-generated operator.
* Switch metrics-bind-address default value back to 8080
This ensures that the upgrade is backwards-compatible.
* Add webhook-related scaffolding
This enables us to easily add support for webhooks by running `operator-sdk create webhook` whenever we want to add them.
* Fix typo
These internal models are introduced to reduce decoupling. The idea is to operate internal model within the project boundaries and convert to appropriate Connect or SDK models in the places where it's necessary.
