tf-spa-minimal

Minimal Terraform configuration for Single Page Applications

Usage

Creating the infrastructure

• Configure terraform.tfvars

aws_region  =   "eu-west-1"
domain_name =   "app.example.com"
name        =   "test-app"
zone_name   =   "example.com."

• Apply Terraform

terraform init
terraform apply

Continuous Delivery

• Add a version

yarn build  # build the SPA, put the results in ./dist
aws s3 sync ./dist s3://YOUR-BUCKET-NAME/v1-2-3
# You can now access https://v1-2-3.app.example.com

• Deploy a version publicly (or revert)

aws lambda update-function-configuration --function-name YOUR-FUNCTION-NAME --environment '{"Variables": {"S3_BUCKET": "YOUR-BUCKET-NAME", "latest": "v1-2-3"}}'
aws cloudfront create-invalidation --distribution-id YOUR-DISTRIBUTION-ID --paths '/*'
# invalidation might take up to 5 minutes, then you can access v1-2-3 at https://app.example.com

Note

For real production use you should add:

• Lifecycle policy and/or Lambda to remove old versions from the bucket
• Manage retention for the Lambda CloudWatch log group
• Proper tagging
• Least privilege IAM policies
