Network configuration for managing Terraform Management Server in Azure

Ensure that the below networking requirements are met.

  • VNet and subnets must be created in Azure account before the Terraform scripts are executed.

  • Required address spaces:

    • For cluster subnet: This subnet is required with /22 or /24 subnet address space ( used for node pool).

    • Load balancer subnet: This subnet is required with - /26 address space (This subnet needs to be empty with no virtual machines / devices installed).

  • Create DNS entries in the Private Hosted Zone:

    • Primary (1): primary.example.com (10.x.x.x)

    • MSDP (1): msdp.example.com(10.x.x.x)

    • Snapshot Manager (1): snapshotmanager.example.com(10.x.x.x)

  • Outbound internet access is required from Terraform Management Server to communicate with resources, services, and the servers.

  • While configuring the components or resources, avoid using prefixes like - netbackup, primary or media. The installation may fail if these keywords are used in the configuration.

  • Azure reserves the first four addresses and the last address, for a total of five IP addresses within each subnet. Refer to the link for more details.

  • AKS cluster nodes require internet access to install addons. Hence it is required to create route table under the resource group with subnets.

  • Terraform server used to deploy Cloud Scale must be able to communicate with the cluster API server for your AKS server.
