Prerequisites
Ensure that the following prerequisites are met before proceeding with the deployment.
A Kubernetes cluster in Azure Kubernetes Service in Azure with multiple nodes. Using separate node pool is recommended for the NetBackup servers, MSDP Scaleout deployments and for different media server objects. It is required to have separate node pool for Snapshot Manager data plane.
Taints and tolerations allows you to mark (taint) a node so that no pods can schedule onto it unless a pod explicitly tolerates the taint. Marking nodes instead of pods (as in node affinity/anti-affinity) is particularly useful for situations where most pods in the cluster must avoid scheduling onto the node.
Taints are set on the node pool while creating the node pool in the cluster. Tolerations are set on the pods.
To use this functionality, user must create the node pool with the following detail:
Add a label with certain key value. For example key = nbpool, value = nbnodes
Add a taint with the same key and value which is used for label in above step with effect as NoSchedule.
For example, key = nbpool, value = nbnodes, effect = NoSchedule
Define storage class of and for primary and for media and MSDPX.
Access to a container registry that the Kubernetes cluster can access, like an Azure Kubernetes Service Container Registry.
Enable AKS Uptime SLA. AKS Uptime SLA is recommended for a better resiliency. For information about AKS Uptime SLA and to enable it, see Azure Kubernetes Service (AKS) Uptime SLA.
Install Cert-Manager. You can use the following command to install the Cert-Manager:
$ kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.6.0/cert-manager.yaml
For details, see https://cert-manager.io/docs/installation/
A workstation or VM running Linux with the following:
Configure kubectl to access the cluster.
Install Azure CLI to access Azure resources.
Configure docker to be able to push images to the container registry.
Free space of approximately 8.5GB on the location where you copy and extract the product installation TAR package file. If using docker locally, there should be approximately 8GB available on the
/var/lib/dockerlocation so that the images can be loaded to the docker cache, before being pushed to the container registry.
