Setup

⚠️ Do not follow these instructions blindly. Please take the time to review the steps and adapt them to your environment.

0. Pre-requisites

• aws-cli
• Terraform 0.15.x+
• Packer
• Node.js 14.x

Clone this repository and follow the instructions below:

1. Build the AWS EC2 AMI

cd infra/images
packer build .

Once the AMI has been built you should be able to see in your AWS console as such:

2. Create a RSA keys to use for accessing the instances

You need to create 2 keys, 1 for staging and 1 for production with this command (feel free to change the file names):

# Create a key pair for the staging environment
ssh-keygen -t rsa -b 4096 -C "ubuntu@staging" -f ~/.ssh/id_staging_cicd

# Create a key pair for the production environment
ssh-keygen -t rsa -b 4096 -C "ubuntu@production"  -f ~/.ssh/id_prod_cicd

3. Add variables to Terraform Cloud

1. Add 4 variables to Terraform Cloud. Feel free to create variable sets and assign them. The variables are:

   

2. Edit your main.tf file and update the backend organization name and workspaces to match your Terraform Cloud organization and workspace:

   terraform {
      backend "remote" {
         organization = "<YOUR_ORG_NAME>"
   
         workspaces {
            name = "<YOUR_WORKSPACE_NAME>"
         }
      }

4. Spin up your EC2 instances from the AMI we built

$ cd infra/instances/production

$ terraform init
$ terraform plan
$ terraform apply

Outputs:

If all goes well, you should see your instances in the console as such:

Do the same for your staging environment.
