Day 51: CI/CD pipeline pt 2

#codebuild #devops #linux

What is CodeBuild?
• AWS CodeBuild is a fully managed continuous integration service.
• It compiles source code, runs tests, and produces deployable artifacts.
• No need to manage build servers — AWS handles scaling and infrastructure for you.
• Commonly used with CodeCommit, CodePipeline, and CodeDeploy.

Tasks for Day 51

Task 01 — Learn & Prep
A. Read about buildspec.yml:
• This file defines all the build commands and settings for CodeBuild.
• Written in YAML, placed at the root of your repo.

version: 0.2

phases:
  install:
    commands:
      - echo Installing dependencies...
  build:
    commands:
      - echo Build started on `date`
      - echo Compiling the application
  post_build:
    commands:
      - echo Build completed on `date`

artifacts:
  files:
    - '**/*'
Enter fullscreen mode Exit fullscreen mode

B. In your CodeCommit repo, create a simple index.html file:

<!DOCTYPE html>
<html>
<head>
    <title>Day 51 - CodeBuild Demo</title>
</head>
<body>
    <h1>Hello from AWS CodeBuild </h1>
</body>
</html>
Enter fullscreen mode Exit fullscreen mode

C. Plan to build it using nginx server inside CodeBuild.

Task 02 — Build with CodeBuild
1. Create a buildspec.yml file in your repo:

version: 0.2

phases:
  install:
    runtime-versions:
      docker: 18
    commands:
      - echo Installing Nginx...
      - yum install -y nginx
  build:
    commands:
      - echo Build started on `date`
      - mkdir -p /usr/share/nginx/html
      - cp index.html /usr/share/nginx/html/index.html
  post_build:
    commands:
      - echo Build completed on `date`
      - echo Artifacts ready for deployment

artifacts:
  files:
    - index.html
Enter fullscreen mode Exit fullscreen mode

D. Push changes to CodeCommit

git add index.html buildspec.yml
git commit -m "Add index.html and buildspec for CodeBuild"
git push origin main
Enter fullscreen mode Exit fullscreen mode

In AWS Console → CodeBuild:

  • Create a new project.
  • Connect it to your CodeCommit repo.
  • Choose environment: Managed image → Amazon Linux 2 → Standard runtime.
  • Use the buildspec.yml you committed.
    1. Start the build → You should see the process install Nginx, copy index.html, and output artifacts.
