Google Cloud Platform

Prerequisites

Download and install terraform.
Verify by the terraform command, it should print a help message that looks similar to that shown below.

$ terraform

Usage: terraform [--version] [--help] <command> [args]
...
Common commands:
    apply              Builds or changes infrastructure
    console            Interactive console for Terraform interpolations
    destroy            Destroy Terraform-managed infrastructure
    env                Workspace management
    fmt                Rewrites config files to canonical format

1. Create a terraform configuration file

First, create a terraform file with provider details.

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

    # The name of your GCP project
    project = "<Your-GCP-Project-Name>"
  }

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-cluster"

   # 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"
  }

2. Create a cluster

Init terraform first if you have not already done so.

$ terraform init

To check what changes are going to happen in 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

3. Verify resources created

The following resources are created by this module:

module.terraform-gcp-yugabyte.google_compute_instance.yugabyte_node The GCP VM instances.

For cluster named test-cluster, the instances will be named yugabyte-test-cluster-n1, yugabyte-test-cluster-n2, yugabyte-test-cluster-n3.

module.terraform-gcp-yugabyte.google_compute_firewall.Yugabyte-Firewall The firwall rule that allows the various clients to access the YugabyteDB cluster.

For cluster named test-cluster, this firewall rule will be named default-yugabyte-test-cluster-firewall with the ports 7000, 9000, 9042 and 6379 open to all.

module.terraform-gcp-yugabyte.google_compute_firewall.Yugabyte-Intra-Firewall The firewall rule that allows communication internal to the cluster.

For cluster named test-cluster, this firewall rule will be named default-yugabyte-test-cluster-intra-firewall with the ports 7100, 9100 open to all other vm instances in the same network.

module.terraform-gcp-yugabyte.null_resource.create_yugabyte_universe A local script that configures the newly created instances to form a new YugabyteDB universe.

4. Destroy the cluster (optional)

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

$ terraform destroy
