Is Flux v2.2.2 compatible with Kubernetes version 1.33?

Flux v2.2 has reached end-of-life support 7 months ago https://endoflife.date/flux

In theory it should work with Kubernetes v1.33, but we don't run conformance tests for EOL versions, I suggest upgrading to Flux 2.6.

Thanks for clarifying. I’ll upgrade to Flux 2.6. Do you have any migration notes or best practices for moving from Flux 2.2 to 2.6?

See the upgrade section in the release notes:

• https://github.com/fluxcd/flux2/releases/tag/v2.3.0
• https://github.com/fluxcd/flux2/releases/tag/v2.4.0
• https://github.com/fluxcd/flux2/releases/tag/v2.5.0
• https://github.com/fluxcd/flux2/releases/tag/v2.6.0

You can jump from 2.2 directly to 2.6, just make sure to update the manifests in Git as instructed in the release notes.

Thanks for pointing me to the release notes and clarifying the upgrade path. I’ll proceed with the 2.6 migration following the guidelines.
