How about listing the various issues and PRs relating to this in the various Jenkins-X repos here, to get an overview and ease cooperation? I'll could start:

Could it be made very clear in the docs what version of Kubernetes is supported? From reading other issues it seems most testing was done on 1.21, but I wouldn't know this by looking at the docs:
e.g. https://jenkins-x.io/v3/admin/platforms/on-premises/#prerequisites

We are close to supporting kubernetes 1.22 fully. A handful PRs remain to be merged, we will get them merged tomorrow.
For now to make it work with kubernetes 1.22, update the tekton and nginx helm charts in the cluster git repo.

• Change the version to 4.0.17 here
• Change the version to 0.29.0 here

You may need to update the certmanager chart version to 1.7.1 here

It would be good if someone does a test, and gives some feedback (I did a test on a local k3s cluster, and the boot job worked, but I will test beyond that today)

Could it be made very clear in the docs what version of Kubernetes is supported?

Yes, we will add it to the docs to make it clear for the end user.

Version stream 0.3.15+ supports kubernetes 1.22 (https://github.com/jenkins-x/jx3-versions/releases).
To get this, upgrade ur jx cli to the latest version using jx upgrade cli (https://jenkins-x.io/v3/admin/setup/jx3/) and then run jx gitops upgrade to update the cluster git repository (https://jenkins-x.io/v3/admin/setup/upgrades/cluster/#manual-upgrades).

Also follow this blog post for breaking changes in tekton: https://jenkins-x.io/blog/2022/04/22/kubernetes-1.22-tekton/

You may or may not need to run this:

k delete job ingress-nginx-admission-patch ingress-nginx-admission-create -n nginx

Run it only if the boot job fails with error related to admission patch and create.

Also, we are working on adding tests which runs on different kubernetes versions, so we can have a compatibility matrix for every new jx3 version released. Atm, we run tests only in one kubernetes version.
