Cluster Setup

Cluster prerequisites

Confidential Containers requires Kubernetes. A cluster must be installed before installing the Helm charts. Many different clusters can be used but they should meet the following requirements.

  • The minimum Kubernetes version is 1.24
  • Cluster must use containerd. Note: cri-o is not tested with the Helm charts for baremetal deployments.
  • At least one node has the label node.kubernetes.io/worker.
  • SELinux is not enabled.
  • Helm 3.8+ is installed.
