Creating a Cluster

When you create a cluster, OCI Cache creates the set of Compute instances that provide caching functionality.

Each cluster is composed of one primary node and optionally one or more data nodes, based on the options that you specify when you create the cluster.

Clusters can only be created in subnets that don't have IPv6 enabled. If you select an existing subnet with IPv6 enabled, cluster creation fails.
    1. Open the navigation menu and click Databases. Under OCI Cache, click Clusters.

    2. Click Create Cluster.

    3. Specify a name for the cluster, select the compartment to create the cluster in, and then click Next.

    4. Optionally change the cluster node configuration options, including the amount of memory in GB configured per node and the number of nodes for the cluster. After you're done updating the settings, click Next.

    5. In Configure networking specify the virtual cloud network (VCN) and subnet for the cluster. Decide whether you want to use an existing VCN and subnet, create a new VCN or subnet, or specify the OCID for an existing subnet. You can't change the cluster's subnet after the cluster has been created.

      If you select an existing VCN or subnet, you can optionally select up to five network security groups (NSGs) for the cluster. The NSGs must already be created for the VCN.


      The NSG you select must contain a rule configured to allow traffic to the cluster's VNIC using specific protocols and ports. For more information, see Security Rule for Connecting to Clusters.
    6. Click Next, review the cluster confirmation details on the Summary page, and then click Create Cluster.

  • Use the oci redis redis-cluster create command and required parameters to create a cluster:

    oci redis redis-cluster create [OPTIONS]
