Build a Serverless CI/CD pipeline on AWS with Fargate, CodePipeline and Terraform

Sat, 20 Jun 2020 20:06:42 +0000

This blog provides an example for deploying a CI/CD pipeline on AWS utilising the serverless container platform Fargate and the fully managed CodePipeline service. We’ll also use Terraform to automate the process for building the entire AWS environment, as shown in the below diagram.

Specifically, we’ll be creating the following AWS resources:

1x demo VPC including public/private subnets, NAT gateway and security groups etc
1x ALB for providing LB services to a target group of 2x Fargate container tasks
1x ECS cluster with a Fargate service definition (running our demo app)
1x CodePipeline definition, which builds the demo app from GitHub Repo (with a webhook trigger) and deploys it to the same Fargate service
1x ECR repository for hosting pipeline build images
2x S3 Buckets as build & artifact cache

References – for this demo, I’m using these Terraform modules found on GitHub:
