Maven
Docker
GitHub Actions
Docker Hub Registry


🚧 Build the JAR using git Maven Repository
on:
  push:
    branches:
      - master
  pull_request:
    branches:
      - master
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up JDK 17
        uses: actions/setup-java@v4
       with:
         java-version: '17'
         distribution: temurin
        cache: maven
      - name: Build with Maven
        run: mvn clean install  
        working-directory: demo-git_action-docker
This generates:

target/springboot_githubaction_demo.jar
🐳 Docker Support
Dockerfile
FROM eclipse-temurin:17-jdk
WORKDIR /app

COPY demo-git_action-docker/target/springboot_githubaction_demo.jar app.jar

EXPOSE 8080
ENTRYPOINT ["java", "-jar", "app.jar"]
🔄 GitHub Actions CI/CD Pipeline
The workflow automatically:

✔ Checks out the code ✔ Installs JDK 17 ✔ Runs Maven build ✔ Builds Docker 
 image ✔ Pushes      image to Docker Hub

## 📌 Notes

* Build context must be `demo-git_action-docker/` so Docker can find the `target/` directory.
* JAR must be generated *before* Docker build.
* The pipeline uses **eclipse-temurin:17-jdk**, a stable replacement for deprecated `openjdk` images.
