Website Setup

#

Prerequisite

#

• Install & Configure AWS CLI

• Install Docker and start its service

• Install Terraform & Ansible

• Create two env files

  • .env

  NODE_ENV=prod
  MONGO_USER=
  MONGO_PASSWORD=
  SESSION_SECRET=
  

  • .env2

  MONGO_INITDB_ROOT_USERNAME=
  MONGO_INITDB_ROOT_PASSWORD=
  

  • Inventory file

Development Setup

#

How to run the project locally

#

• Install npm packages

npm install

Build the Docker image and run the container

#

sudo docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d

You can access the application on localhost:3000 and hit the /blogserver .

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.

CI Setup

#

After creating EC2 instance, copy the IP address of ec2 instance to inventory.ini file (in ansible directory)

[pipeline]
<paste ip address here> ansible_ssh_private_key_file=/home/harisheoran/my-key.pem ansible_user=ubuntu

Set your path of ansible_ssh_private_key (your aws key pair value file)
