terraform-aws-fargate-wordpress

Terraform module which deploys Wordpress on AWS using ECS Fargate for compute, RDS for database and an application load balancer.

There are the features and services involved for the stack :

ECS and Fargate for the containers
RDS Aurora Serverless for the database
Route53 for DNS
Cloudfront as CDN
ALB and ASG for availability
Spot for 50% of the containers
ECS Exec to allow you to connect to your container
EFS for data persistence
ACM for SSL certificate management
KMS for encryption key management
IAM, SG, CW and VPC (but how could we live without them)
of course Terraform and Wordpress :)

PREREQUISITES

An exisiting Route53 public hosted zone should be present
You should define those 3 variables

variable "domain_name" {
  default = "mydomain.tld"
}

variable "wp_subdomain" {
  default = "wordpress"
}

variable "route53_zone_id" {
  default = "CHANGE_HERE"
}

  db_subnet_group_subnet_ids = module.vpc.database_subnets
  domain_name                = "${var.wp_subdomain}.${var.domain_name}"
  cnames                     = ["${var.wp_subdomain}.${var.domain_name}"]
