Serverless CI/CD with AWS CodePipeline

Create a new pipeline

• name: navien-installer-infrastructure
• Service role: New service role
• Role name: automatically populated

Add source stage

• Provider: Github
• Use “Connect to Github”
• Change detection options: Github webhooks (recommended)
• branch: refs/head/master

You can specify tag, branch, or pull request. I simply put branch name, as I want this to run when it gets merged into master branch. For local development, I would run “sls deploy” manually

Add build stage

• Provider: AWS CodeBuild
• Region: Europe (Ireland)
• Create a new project

If you haven’t created a project, create one now

Project

• Name: navien-installer-infrastructure
• Environment image: Managed image
• Operating system: Ubuntu
• Runtime: Standard
• Image: aws/codebuild/standard:4.0
• Image version: Always use the latest
• Environment type: Linux
• Service role: New service role

Role

Initially, I encountered an error because the role this pipeline uses doesn’t have enough permission to create a stack. To enable serverless framework to create a new stack, I have the below permissions.

• AWSLambdaFullAccess
• IAMFullAccess
• AmazonAPIGatewayAdministrator
• CloudFormationAdministrator

Buildspec

Buildsec is a yaml file that speifies build steps.

version: 0.2
env:
  variables:
    DOTNET_ROOT: /root/.dotnet
phases:
  install:
    runtime-versions:
      dotnet: 2.1
  pre_build:
    commands:
      - npm install -g serverless
      - cd src
      - cd Navien.Installers.Lambdas
      - dotnet clean
      - dotnet restore
  build:
    commands:
      - ./build.sh
      - serverless deploy --stage cicd | tee deploy.out

Add deploy stage

I’v skipped this stage as “serverless deploy” will do the deployment.
