Stable Helm Charts

All the available charts can be found in artifacthub.io.

NOTE: NRI-plugins Helm installation has been successfully verified in both local clusters and major Cloud Providers’ managed clusters, including:

  • AWS EKS

    • kubernetes version: 1.28.x

    • containerd version: 1.7

    • node image: Amazon Linux 2, Ubuntu 20.04,

  • Google GKE

    • kubernetes version: 1.28.x

    • containerd version: 1.7

    • node image: Container-Optimized OS from Google (COS), Ubuntu 22.04

  • Azure Kubernetes Service

    • kubernetes version: 1.28.x

    • containerd version: 1.7

    • node image: Azure Linux Container Host, Ubuntu 20.04

While Ubuntu 20.04/22.04 was used across all three CSP environments, it’s worth noting that node images are not limited to Ubuntu 20.04/22.04 only. The majority of widely recognized Linux distributions should be suitable for use.

Unstable Helm Charts

Helm charts are also published from the main/development branch after each merge. These charts reference the latest development images tagged as unstable and are are stored alongside plugin images in the OCI image registry.

Discovering Unstable Helm Charts

Unstable charts can be discovered using skopeo. For instance, one can list the available charts for the balloons plugin using this skopeo command: skopeo list-tags docker://ghcr.io/containers/nri-plugins/helm-charts/nri-resource-policy-balloons

Using Unstable Helm Charts

Once discovered, unstable Helm charts can be used like any other. For instance, to use the v$X.$Y-unstable version of the chart to install the development version of the balloons plugin one can use this command: helm install --devel -n kube-system test oci://ghcr.io/containers/nri-plugins/helm-charts/nri-resource-policy-balloons --version v$X.$Y-unstable --set image.tag=unstable --set image.pullPolicy=Always
