Oracle Cloud Native Environment
Install Oracle Cloud Native Environment
Deploy Oracle Cloud Native Environment with the Kubernetes module, following instructions from Oracle Cloud Native Environment: Getting Started.
- Install a Kubernetes network load balancer implementation, such as OCI-CCM or MetalLB.
- Install a Container Storage Interface Driver, such as OCI-CCM or Gluster.
Notes
The oci-ccm
module does not elect a default StorageClass
or configure policies for the CSIDrivers
that it installs. A
reasonable choice is the oci-bv
StorageClass
with its CSIDriver
configured with the File
group policy.
kubectl patch sc oci-bv -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
kubectl apply -f - <<EOF
apiVersion: storage.k8s.io/v1
kind: CSIDriver
metadata:
name: blockvolume.csi.oraclecloud.com
spec:
fsGroupPolicy: File
EOF

Examples
Oracle Cloud Infrastructure
The following is an example of Oracle Cloud Infrastructure that can be used to evaluate Verrazzano installed on Oracle Cloud Native Environment. If other environments are used, the capacity and configuration should be similar.You can use the VCN Wizard of the Oracle Cloud Infrastructure Console to automatically create most of the described network infrastructure. Additional security lists/rules, as detailed in the following sections, need to be added manually. All Classless Inter-Domain Routing (CIDR) values provided are examples and can be customized as required.
Virtual Cloud Network (for example, CIDR 10.0.0.0/16)
Public Subnet (for example, CIDR 10.0.0.0/24)
