MongoDb Replica

This stack creates a MongoDb replica:

• create “n” number of replicas into an existing VPC
• create one data volume per VM
• create mongodb keys: ssh, pems, and keyfile
• place mongodb cluster in private subnet
• configure mongodb replica through a bastion host
• limit access through existing database security group
• use spot instances (optional)

Prerequisites

Completed getting started guide for creating IAM and VPC .

Add Project to ED

• Go to Home -> click Add Project
• Select and Click launch-ed as the launch repository
• Type branch name >> mongodb
• Add project name >> mongodb-101
• Click Add Project

Customized elasticdev.yml

You can create your own elasticdev.yml. (optional)
