Azure-weka deployment Terraform package

The Weka cluster on Azure provides a fast and scalable platform to run, for example, performance-intensive applications and hybrid cloud workflows. It can also be used for object stores, tiering, and snapshots using the Azure Blob service. The provided Azure-Weka Terraform package contains modules and examples you can customize according to your deployment needs. The installation is based on applying the customized Terraform variables file to a predefined Azure subscription. Applying the Terraform variables file performs the following:

  • Creates resources in a predefined resource group, such as virtual machines, network interfaces, function app, load balancer, and more.
  • Deploys Azure virtual machines.
  • Installs the Weka software.
  • Configures the Weka cluster.

Usage

module "deploy-weka" {
   source                = "weka/weka/azure"
   prefix                = "weka"
   rg_name               = "myResourceGroup"
   vnet_name             = "weka-vpc-0"
   subnets               = ["weka-subnet-0"]
   sg_id                 = "security-group-id"
   get_weka_io_token     = "get_weka_io_token"
   cluster_name          = "myCluster"
   set_obs_integration   = false
   instance_type         = "Standard_L8s_v3"
   cluster_size          = 6
   private_dns_zone_name = "myDns.private.net"
}
