Project 5 - Mongo DB Cluster Deployment on AWS w/ Ansible

Write an ansible playbook to configure 3 VMs in Amazon AWS as a Mongo DB cluster.

Deployment Steps

• Create and download key pair from: AWS EC2 Keypair Link
• SSH setup:
  • ssh-agent bash
  • ssh-add {LocationToPemFile}
• Generate three Elastic IPs from: AWS Elastic IPs Link
• Create or modify a security group to allow all traffic(inbound and outbound) at: AWS Security Group Link
  NOTE: write down the security group name
• Launch three EC2 ubuntu instances from: AWS EC2 Instance Link
  NOTE: Use the same security group you previously modified. After launching one instance, can use 'launch more like this' to simplify
• Attach the previously created Elastic IPs to the EC2 instances
• Make the elastic IP entries in the 'hosts' file under groups
  • [mongod_primary]: One Instance IP
  • [mongod_secondary]: Two Instance IPs
• ssh-keygen -f "/home/{yourusername}/.ssh/known_hosts" -R {IP}
  NOTE: Only if required, i.e., Key signature changes on every time an instance is destroyed and created.
• ssh-keyscan {IP} >> ~/.ssh/known_hosts
  NOTE: Add instance signatures to known hosts
• use the script.sh to run the playbook
