====== CodeBuild ======

**What it is:** A managed build service that compiles code, runs tests, and produces build artifacts.

**What it’s for:**
  * Build and test applications automatically.
  * Create container images (often pushing to ECR).
  * Reduce need to manage build servers.

**Key ideas:**
  * Builds run in isolated environments.
  * You define build steps in a buildspec file.

**Exam cues:**
  * “compile and run tests automatically” → CodeBuild.
  * “build Docker image and push to ECR” → CodeBuild + ECR.

**Hard words:**
  * *compile* /kəmˈpaɪl/: biên dịch
  * *artifact* /ˈɑːrtɪfækt/: sản phẩm build (file đầu ra)
  * *isolated* /ˈaɪsəleɪtɪd/: cô lập
  * *pipeline* /ˈpaɪplaɪn/: chuỗi công đoạn CI/CD
