Instructions

You can use terraform on its own to spin up a number of Red Hat Enterprise Linux EC2 instances in AWS (version 9.x) with the resources needed to install AAP as a hybrid node configuration

Feel free to set the variables how you see fit

Terraform also produces a dynamic Ansible inventory file that can be used in playbooks for configuring this sytems.

Prerequisits

Install the following on your local system:

• AWS cli
• terraform
• ansible (core)

To run the terraform script on its own

terraform init
terraform apply (type "yes" when prompted)

output shows all the public IP addresses, as well as a cli string to ssh into one of them.

delete everything by typing
terraform destroy

To run them on one swoop

I have created a helper script called 'rhel-provision-and-config.sh' that calls terraform and then ansible

sh ./rhel-provision-and-config.sh <optional number of instances>
examples:

Just one ec2 instance (default)
sh ./rhel-provision-and-config.sh

ec2 instances == 3
sh ./rhel-provision-and-config.sh 3

you can also unregister the instance from Red Hat Insights and subscription by running the helper script
rhel-deprovision-and-unregister.sh

this will also terminate the EC2 instance in AWS

run terraform destroy afterwards if needed

For RHEL Insight Setup, run these scripts instead

Additional playbooks have been added to register your EC2 instances with a RHEL subscription and add them to Insights inventory:

• rhel-reg-insights.yml

Usage:
ansible-playbook -i inventory rhel-reg-insights.yml --vault-id @prompt

Note:
vault data set in vars/reg-data.yml and must be encrypted with ansible-vault

ansible-vault edit vars/reg-data.yml
.
.
username: <RH Subscription Username>
password: <RH Subscription Password>

Playbook to remove EC2 instances from the Insights inventory and unregister them:

• rhel-unreg-insights.yml

Scripts to provision/deprovision and register/unregister have been created as well:

• rhel-provision-and-register.sh
• rhel-deprovision-and-unregister.sh

Additional Notes
