Night of the CI: Bright Health

A very short slide for the Austin Cloud User Group Night of the CI meeting. This is a snapshot of how Bright Health is building software at the start of our life as an engineering team.

Transcript

1. 1 Prototyping apps quickly on a dime. MVP CI at Bright Health
2. • Requirements • Version 1 • Version 2 • Towards Version 3 Contents
3. • Bright Health is a small show (>10 developers) and is just starting to build our MA front-end and APIs • Nothing is in production yet and won’t be until Q3 • Focus is on getting a simple CI pipeline working now, iterating later Requirements
4. • Default VPC • Two EC2 Instances • One container running on each instance via systemd • ALB for basic load balancing Version 1: Architecture
5. Version 1: CI Pipeline 1. GitHub: PR Hits master. 2. CircleCI: Webhook is fired to CCI, container is built. 3. Docker Hub: CCI pushes the image. 4. My boss: ssh into the instance, pull new container, modify service file, restart service.
6. • Continuously Integrating code, but manually deploying artifacts • Development effectively stops while waiting for the build to complete • No ability to easily roll back Version 1: Downsides
7. Version 2: Architecture • Default VPC • One ECS Cluster • One ECS Service running two containers • ALB for basic load balancing
8. Version 2: CI Pipeline 1. GitHub: PR Hits master. 2. CircleCI: Webhook is fired to CCI, container is built. 3. AWS ECR: CCI pushes the image to the ECR. 4. AWS ECS: CCI runs a deployment script to create a task definition and update the service.
9. • No versioning • Using one cluster and one environment • From start of build to new service roll out > 15 minutes • CircleCI only builds one container a time for our entire account Version 2: Downsides
10. • Replace CircleCI with AWS CodeBuild and / or Jenkins • Create Clusters for Staging and Production • Introduce Semantic Versioning into our artifacts • Add in more automated testing Towards Version 3
