Environment

Operator type:

Kubernetes cluster type:

$ operator-sdk version

1.35.0

$ go version (if language is Go)

1.22

$ kubectl version

Possible Solution

Additional context

Go 1.21 is supported (=getting security fixes) only until August 2024 when Go 1.23 is expected to be released. It would make sense to add support for Go 1.22 or even 1.23 by then (Go 1.23 release candidates are already available).

What's needed to make this happen? Go 1.21 is no longer supported by Google, and we're starting to run into dependency conflicts with other packages who have already upgraded.

Hi @siggimoo If you follow the below issue

• #6730

the items in this list are what is needed to update to go 1.22. Right now a few folks are working on the ansible-operator-plugin to resolve dependency issues, move to UBI9, then we can update that to project to the next version of kubebuilder/k8s there. After that we can then work on migrating operator-sdk to the next version of kubebuilder/k8s/UBI9.
