terraform-gcp-yugabyte

A Terraform module to deploy and run YugabyteDB on Google Cloud.

Config

• First create a terraform file with provider details

  provider "google" 
  { 
    # Provide your GCP Creadentilals 
    credentials = "${file("yugabyte-pcf-bc8114281026.json")}"
  
    # The name of your GCP project 
    project = "yugabyte-pcf"
  }
  

  Note :- You can get credentials file by following steps given here

• Now add the yugabyte terraform module to your file

  module "yugabyte-db-cluster" {
  source = "github.com/YugaByte/terraform-gcp-yugabyte.git"
  
  # The name of the cluster to be created.
  cluster_name = "test-yugabyte"
  
   # key pair.
  ssh_private_key = "SSH_PRIVATE_KEY_HERE"
  ssh_public_key = "SSH_PUBLIC_KEY_HERE"
  ssh_user = "SSH_USER_NAME_HERE"
  
  # The region name where the nodes should be spawned.
  region_name = "YOUR VPC REGION"
  
  # Replication factor.
  replication_factor = "3"
  
  # The number of nodes in the cluster, this cannot be lower than the replication factor.
  node_count = "3"
  }
  

Usage

Init terraform first if you have not already done so.

$ terraform init

To check what changes are going to happen in the environment run the following

$ terraform plan

Now run the following to create the instances and bring up the cluster.

$ terraform apply

Once the cluster is created, you can go to the URL http://<node ip or dns name>:7000 to view the UI. You can find the node's ip or dns by running the following:

terraform state show google_compute_instance.yugabyte_node[0]

You can access the cluster UI by going to any of the following URLs.

You can check the state of the nodes at any point by running the following command.

$ terraform show

To destroy what we just created, you can run the following command.

$ terraform destroy

Note:- To make any changes in the created cluster you will need the terraform state files. So don't delete state files of Terraform.
