• Create a .env file for environment variables

NODE_ENV=
MONGO_USER=
MONGO_PASSWORD=
SESSION_SECRET=

Production Setup

Infrastructure as Code

Run the Terrafrom File to launch 2 ec2 instances

cd terraform

terraform init

terraform apply

It'll output 2 IP addresses, copy them(You'll need to configure our ec2 instances).

Configuration Management

For Pipeline

Using Ansible

• First, we configure the Pipeline server

cd ansible

Paste the IP address in inventory.ini

ansible-playbook -i ./inventory.ini ./pipeline.yml 

It'll install Jenkins on EC2 and start serving on port 8080.

Now install basic plugins and some additional plugins like

• Github Integration

For main server

Now, configure the main ec2 instance, execute the following command

ansible-playbook -i ./inventory.ini ./run_app.yml 

Web application will start serving at public ip address of ec2 instance.
