Compatibility matrix with k8s

[tomas-balaz]

Hey guys!

Can I find a compatibility matrix or all supported k8s versions somewhere in the Docs?

A compatibility matrix could be essential for users to quickly determine whether the Vector is compatible with their specific Kubernetes version, thus ensuring a smooth integration and usage experience.

I will upgrade k8s to 1.26, 1.27, respectively, and I don't know if Vector supports these k8s versions.

Hi @tomas-balaz ! You can see the versions we test against in CI here:

vector/.github/workflows/k8s_e2e.yml
