<p>I am trying to create a 3 node MongoDB replica set using automation (ansible or terraform) in AWS. I am able to do this in the management console of AWS, but I'm not sure how to approach it.</p>

<p>Essentially, the script must create the instances and then set up a 3 node MongoDB replica set on them. I want to add an EBS disk on it and then maybe secure it.</p>

<p>All of this via Ansible (or Terrafor) so I can automate it fully.</p>

<p>Is this possible?</p>

hi Prim3. This sounds eminently doable with both Ansible and Terraform. The answer to your question is undoubtedly simply "yes". Perhaps you could narrow down the question a bit - what _aspects_ of this task seem difficult, complicated or uncertain to you?

@BruceBecker I want to do the same but I couldn't find simple and clear tutorial/article to do this. Can you please guide me to right direction.

# Creating ec2 instances and installing mongoDB using automation

(Asked by: username_0 on 2020-04-02)

I am trying to create a 3 node MongoDB replica set using automation (ansible or terraform) in AWS. I am able to do this in the management console of AWS, but I'm not sure how to approach it.

Essentially, the script must create the instances and then set up a 3 node MongoDB replica set on them. I want to add an EBS disk on it and then maybe secure it.

All of this via Ansible (or Terrafor) so I can automate it fully.

Is this possible?

Thanks!!

It's possible. I would use Terraform for creating the infrastructure on AWS and Ansible for provisioning. You will have to write .tf files and ansible-playbooks in order to do this.

Just to let you know, if all 3 nodes are equal you should do the installation and provisioning once and then create an AMI to set up the rest. Maybe an [autoscaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html) group is a possibility too.

Keep in mind that AWS provides [documentdb](https://aws.amazon.com/es/documentdb/) as document-oriented database as a service. It's not mongoDB but it's pretty similar (there are some functions mongo provides and docdb doesn't).
