About AddonMatrix
AddonMatrix answers a narrow question for platform and SRE engineers: does this add-on’s project say it works on this Kubernetes minor, including the minor your EKS, AKS, or GKE cluster is on?
It is the sister site of EOL Radar (opens in a new tab), which tracks end-of-support dates for the managed platforms. AddonMatrix is built by the maintainer of EOL Radar.
How a cell gets its value
- The source is the project’s own docs, README, or release notes. Each add-on page links them.
- A cell is filled only when that source lists the combination, a closed support range, or a minimum version. “Tested” and “supported” stay different words when the project uses them differently.
- If the project does not publish a matrix, the page says so and quotes what the project does say. Those add-ons have no green cells.
- Kubernetes, EKS, AKS, and GKE dates come from endoflife.date (opens in a new tab). They describe the platform, not the add-on.
- A weekly GitHub Action re-fetches each source and the GitHub Releases API. It opens a pull request when the page or the latest release changes. It does not rewrite the matrix by itself.
