Terraform Live Repository for the Production environment

acme-terraform-live-prod

Terraform Live Repository for the Production environment

Getting Started

Create a Google Cloud Platform project through the web console. Make a note of the project ID.

Create a service account for the project through the IAM section of the web console.

The service account must have the following roles:

• Compute Instances Admin (v1)
• Compute Network Admin
• Compute Security Admin
• Storage Admin

Download the credentials of the service account as a JSON file and place it in gcloud/credentials.json

Create an SSH key by running: ssh-keygen -f gcloud/ubuntu

Create an environment file located at gcloud/.env with the following contents:

export TF_VAR_engineer_cidrs="[\"$(dig +short myip.opendns.com @resolver1.opendns.com)/32\"]"
export GOOGLE_APPLICATION_CREDENTIALS="../credentials.json"
export GCLOUD_PROJECT="<project-id>"
export GCLOUD_REGION="us-west1"

The environment file must be sourced before working with Terraform:

source gcloud/.env

state_bucket

Creates the bucket that will hold the Terraform state.

cd gcloud/state_bucket
terraform init
terraform get -update
terraform apply

Change the content in the state.tf to a gcs backend:

terraform {
  backend "gcs" {
    bucket  = "acme-terraform-live-prod"
    prefix  = "gcloud/state_bucket/terraform.tfstate"
  }
}

Re-run terraform init and agree to the proposition of copying the existing local state to the newly configured GCS backend.

network

Creates a vpc network and subnetworks to deploy servers into.

cd ../network
terraform init
terraform get -update
terraform apply

db

Creates a database server, which holds the data for the client.

cd ../db
terraform init
terraform get -update
terraform apply

job

Creates a jobs server, which inputs data into the database.

cd ../job
terraform init
terraform get -update
terraform apply

app

Creates an application server to present the data from the database.

cd ../app
terraform init
terraform get -update
terraform apply
