Azure-WEKA Terraform package description

The Azure-WEKA Terraform package contains modules and examples to customize the WEKA cluster installation on Azure. The default protocol deployed using the Terraform package is POSIX. The Azure-WEKA Terraform package supports the following deployment types:

• Public cloud deployments: Require passing the get.weka.io token to Terraform for downloading the WEKArelease from the public get.weka.io service. The following examples are provided:

  • Public network.

  • Public network with an existing network.

  • Public network with multiple clusters.

  • Public network with existing object stores.

• Private cloud deployments: Require uploading the WEKA release tar file into an Azure blob container from which the virtual machines can download the WEKA release. The following examples are provided:

  • Private network with an existing network.

  • Private network with multiple clusters.

  • Private network with peering.

Terraform variables file

Each deployment type includes a variables file vars.auto.tfvars that contains only the variables required for the relevant deployment type.

The following is an example of a public network with an existing network variables file.

Public network with an existing network: vars.auto.tfvars example

The public network with an existing network, in which the network-related resources are already provisioned.

As part of the deployment, you customize the values according to your deployment.

prefix                = "mySystemPrefix"
rg_name               = "myResourceGroup"
vnet_name             = "myVnet"
subnet_name_list      = ["mySubnet-0"]
cluster_name          = "myCluster"
instance_type         = "Standard_L8s_v3"
set_obs_integration   = true
tiering_ssd_percent   = 20
cluster_size          = 6

Note: This is just one example of the variables files. The other examples may include more variables according to the deployment type.

Variable descriptions

Variable	Description
prefix	The prefix for all the resource names. For example, the prefix for your system name.
rg_name	A predefined resource group in the Azure subscription.
vnet_name	The virtual network name.
subnets_name_list	The subnet name list.
cluster_name	The cluster name.
instance_type	The virtual machine type to deploy. See Supported virtual machine types.
set_obs_integration	Determines whether to enable object stores on the WEKA cluster.
tiering_ssd_percent	When set_obs_integration is set to true, this variable sets the capacity percentage of the filesystem that resides on SSD. For example, for an SSD with a total capacity of 20GB, and the tiering_ssd_percent is set to 20, the total available capacity is 100GB.
cluster_size	The number of virtual machines to deploy. The minimum value is 6.

Name values must be in lowercase and without special characters. The total number of characters of the prefix+ rg_name + cluster_name, must not exceed 24 characters.
