How to Automate Spring Boot Deployment with Jenkins and Docker in One Click

1. Install Docker

Update yum, remove any old Docker packages, install required utilities, add the Docker CE repository, then install Docker CE. Start Docker, enable it to start on boot, and verify the installation with docker version.

2. Install Jenkins

Run Jenkins in a Docker container:

docker run --name jenkins -u root --rm -d -p 8080:8080 -p 50000:50000 -v /var/jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean

Access http://{SERVER_IP}:8080, unlock Jenkins by retrieving the initial admin password from /var/lib/jenkins/secrets/initialAdminPassword, install the recommended plugins, and create an admin user.

3. System Configuration

Install required plugins such as Maven Integration , Publish Over SSH , and Gitee (if using Gitee). Configure Maven in Manage Jenkins → Global Tool Configuration by adding a Maven installation.

4. Create Job

Create a new freestyle project, set the Git repository URL and credentials, add a build step that runs Maven: clean install -Dmaven.test.skip=true Save the job.

5. Test Build

Trigger the build, view the console output to ensure the JAR is produced, and check the workspace for the generated artifact.

6. Run Project

Create a Dockerfile in the Spring Boot project root:

FROM jdk:8
VOLUME /tmp
ADD target/zx-order-0.0.1-SNAPSHOT.jar app.jar
EXPOSE 8888
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar","--spring.profiles.active=prd"]

Modify the Jenkins job to stop/remove any existing container, build a new Docker image, and run it:

cd /var/jenkins_home/workspace/zx-order-api
docker stop zx-order || true
docker rm zx-order || true
docker rmi zx-order || true
docker build -t zx-order .
docker run -d -p 8888:8888 --name zx-order zx-order:latest

Verify the container is running with docker ps and check logs with docker logs zx-order.
