Prerequisites

Review the prerequisite requirements and the software versions supported by Verrazzano

Verrazzano requires the following:

  • A Kubernetes cluster and a compatible kubectl.

  • Two load balancers. Note that in a Verrazzano multicluster environment, two load balancers are required for each cluster.

  • dev profile - Each node in the cluster should contain at least two CPUs, 16 GB RAM, and 100 GB of disk storage. The entire cluster requires at least six CPUs, 48 GB RAM, and 100 GB of disk storage. In addition, about 52 GB of storage is required for the persistent volumes.

  • prod profile - Each node in the cluster should contain at least four CPUs, 32 GB RAM, and 100 GB of disk storage. The entire cluster requires at least eight CPUs, 64 GB RAM, and 150 GB of disk storage. In addition, about 450 GB of storage is required for the persistent volumes.

    The storageClassName is not available for all the components where you configure persistent volumes, therefore, when it is not specified, the default StorageClass from the cluster is used.

Supported hardware

Verrazzano requires x86-64; other architectures are not supported.
