Wordpress on Fargate

This terraform example demonstrates how to run a scalable wordpress site. In this exmaple, we have tried to use serverless technologies as much as possible. Hence, we chose to run the site on fargate and are using Aurora serverless as DB.

Read more about this on the blog Terraform Recipe for WordPress on Fargate

AWS Services

We used the below AWS services in our example. The main motivation behind the selection of services is that we select as many serverless components as possible.

  • Fargate - for computing
  • Aurora Serverless - for database
  • EFS (Elastic File System) - for persistent data storage
  • Cloudfront - CDN

Terraform setup

Initialize terraform environment

terraform init -backend-config="bucket=<BUCKET_NAME>" -backend-config="profile=<AWS_PROFILE>" -backend-config="region=<AWS_REGION>"

Create environment

  AWS_SDK_LOAD_CONFIG=1 \
  TF_VAR_site_domain=<PUBLIC_DOMAIN> \
  TF_VAR_public_alb_domain=<INTERNAL_DOMAIN_FOR_ALB> \
  TF_VAR_db_master_username=<DB_MASTER_USERNAME> \
  TF_VAR_db_master_password="<DB_MASTER_PASSWORD>" \
  AWS_PROFILE=<AWS_PROFILE> \
  AWS_DEFAULT_REGION=<AWS_REGION> \
  terraform apply

Tear down

  AWS_SDK_LOAD_CONFIG=1 \
  TF_VAR_site_domain=<PUBLIC_DOMAIN> \
  TF_VAR_public_alb_domain=<INTERNAL_DOMAIN_FOR_ALB> \
  TF_VAR_db_master_username=<DB_MASTER_USERNAME> \
  TF_VAR_db_master_password="<DB_MASTER_PASSWORD>" \
  AWS_PROFILE=<AWS_PROFILE> \
  AWS_DEFAULT_REGION=<AWS_REGION> \
  terraform destroy

p.s. Instead of environment variables, you can obviously use .tfvar files for assigning values to terraform variables.
