Elemental Lifecycle Manager is a Kubernetes controller capable of performing upgrades for Elemental created environments.
Elemental Lifecycle Manager utilizes SUC to perform OS and Kubernetes upgrades.
Ensure that it is installed on the cluster by either:
- Manually deploying the
system-upgrade-controller.yamlfile from the desired SUC release. - Deploying it from the SUC chart located under the https://charts.rancher.io Helm repository.
Additional components installed on the cluster via Helm charts are being upgraded by the Helm Controller. RKE2 clusters have this controller built-in. It is enabled by default and users of the Elemental Lifecycle Manager should ensure that it is not manually disabled via the respective CLI argument or config file parameter.
