AWS EC2 HA Cluster is a Terraform template for provisioning a high-availability EC2 cluster with Auto Scaling Groups and an Application Load Balancer.
EC2 running Auto Scaling Groups with Application Load Balancer
This tool is primarily used for deploying a highly available EC2 cluster in AWS, making it suitable for developers and system administrators looking to ensure uptime and scalability of their applications. It automates the creation of infrastructure components and handles encryption for security.
Ensure that you have the necessary AWS permissions and IAM roles configured for KMS and Auto Scaling operations.
Create a temporary key pair using 'ssh-keygen -f ./tmp_rsa'
Initialize Terraform in the 'ami' directory with 'terraform -chdir="ami" init'
Apply the Terraform configuration in the 'ami' directory with 'terraform -chdir="ami" apply -auto-approve'
Create the AMI and encrypted snapshots as per the commands provided in the README
Create the 'cluster/.auto.tfvars' file with the appropriate AMI ID and KMS key ARN
Initialize Terraform in the 'cluster' directory with 'terraform -chdir="cluster" init'
Apply the Terraform configuration in the 'cluster' directory with 'terraform -chdir="cluster" apply -auto-approve'
Clean up resources using 'terraform -chdir="cluster" destroy -auto-approve' and 'terraform -chdir="ami" destroy -auto-approve'ssh-keygen -f ./tmp_rsa
Creates a temporary key pair for SSH access.
terraform -chdir="ami" init
Initializes Terraform in the 'ami' directory.
terraform -chdir="ami" apply -auto-approve
Applies the Terraform configuration to create the base infrastructure.
aws ec2 create-snapshot --volume-id 'vol-0123456789abcdef' --description 'Unencrypted'
Creates an unencrypted snapshot of a specified volume.
aws ec2 copy-snapshot --source-region 'sa-east-1' --source-snapshot-id 'snap-0123456789abcdef' --encrypted
Copies a snapshot and encrypts it.
aws ec2 register-image --name "ec2ha-encrypted" --region='us-east-2' --description "AMI_from_snapshot_EBS"
Registers an AMI from the encrypted snapshot.
terraform -chdir="cluster" init
Initializes Terraform in the 'cluster' directory.
terraform -chdir="cluster" apply -auto-approve
Applies the Terraform configuration to create the EC2 cluster.
curl http://ec2ha-lb-0123456789.sa-east-1.elb.amazonaws.com
Accesses the Apache server using the load balancer URL.
terraform -chdir="cluster" destroy -auto-approve
Destroys the resources created in the 'cluster' directory.
