Keycloak is an open-source identity management platform that provides authentication and authorization for applications. It supports Single Sign-On (SSO), OIDC, SAML, and Multi-Factor Authentication (MFA). Deploying Keycloak on AWS ECS with Fargate using Terraform offers scalability, security, and cost-efficiency.
You Should Know:
Terraform Setup for Keycloak on AWS ECS Fargate
Below are the essential Terraform configurations and commands to deploy Keycloak on AWS:
1. Initialize Terraform
terraform init
2. Define AWS Provider
provider "aws" {
region = "us-east-1"
}
3. Create ECS Cluster
resource "aws_ecs_cluster" "keycloak_cluster" {
name = "keycloak-cluster"
}
4. Configure Fargate Task Definition
resource "aws_ecs_task_definition" "keycloak" {
family = "keycloak"
network_mode = "awsvpc"
requires_compatibilities = ["FARGATE"]
cpu = "1024"
memory = "2048"
execution_role_arn = aws_iam_role.ecs_execution_role.arn
container_definitions = jsonencode([{
name = "keycloak",
image = "quay.io/keycloak/keycloak:latest",
portMappings = [{
containerPort = 8080,
hostPort = 8080
}],
environment = [
{ name = "KEYCLOAK_ADMIN", value = "admin" },
{ name = "KEYCLOAK_ADMIN_PASSWORD", value = "securepassword" }
]
}])
}
5. Deploy ECS Service
resource "aws_ecs_service" "keycloak_service" {
name = "keycloak-service"
cluster = aws_ecs_cluster.keycloak_cluster.id
task_definition = aws_ecs_task_definition.keycloak.arn
launch_type = "FARGATE"
desired_count = 1
network_configuration {
subnets = [aws_subnet.public_subnet.id]
security_groups = [aws_security_group.keycloak_sg.id]
assign_public_ip = true
}
}
6. Apply Terraform Configuration
terraform plan terraform apply -auto-approve
Key Commands for Keycloak Management
- Access Keycloak Admin Console:
kubectl port-forward svc/keycloak 8080:8080 If using Kubernetes
Then open `http://localhost:8080`
-
Export Keycloak Realm Configuration:
kcadm.sh get realms/demo -r master --no-config --fields id,name
-
Enable MFA in Keycloak:
kcadm.sh update realms/demo -s 'otpPolicyAlgorithm=HmacSHA1'
AWS CLI Commands for Monitoring
-
Check ECS Task Status:
aws ecs describe-tasks --cluster keycloak-cluster --tasks <TASK_ID>
-
View CloudWatch Logs:
aws logs tail /aws/ecs/keycloak --follow
What Undercode Say
Deploying Keycloak on AWS ECS with Fargate using Terraform provides a scalable and secure identity management solution. By leveraging infrastructure-as-code, teams can ensure reproducibility and compliance. Additional optimizations include:
– Using AWS Graviton for cost savings.
– Enabling Auto Scaling for high availability.
– Integrating Secrets Manager for secure credential storage.

Prediction
As cloud-native identity management grows, Keycloak adoption will rise, especially in hybrid environments requiring self-hosted SSO solutions.
Expected Output:
- Keycloak running on AWS ECS Fargate.
- Terraform-managed infrastructure.
- Secure authentication with OIDC & MFA support.
