One-Click Automated Deployment of Spring Boot with Jenkins and Docker

This article provides a step‑by‑step tutorial for building a complete CI/CD pipeline that automatically builds, packages, and deploys a Spring Boot application using Docker and Jenkins.

1. Install Docker

Prepare the CentOS host, update packages, remove any old Docker versions, install required utilities, add the Docker CE repository, and install Docker.

yum update

yum remove docker docker-common docker-selinux docker-engine

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum install docker-ce

systemctl start docker

systemctl enable docker

docker version

2. Install Jenkins

Run Jenkins in a Docker container, then access the web UI on port 8080. Unlock Jenkins by retrieving the initial admin password from the 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

Obtain the password:

docker exec -it jenkins bash
cat /var/lib/jenkins/secrets/initialAdminPassword

3. System Configuration

Install required plugins such as Maven Integration and Publish Over SSH. Configure Maven in Manage Jenkins → Global Tool Configuration and set the Maven installation path.

4. Create Job

Create a freestyle job, add the Git repository, and define a build step that invokes Maven to package the project and then builds a Docker image.

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

5. Test and Run

Trigger the build, monitor the console output, and verify the container is running with docker ps. Access the application via http://{host_ip}:8888 to confirm successful deployment.

docker ps

docker logs zx-order

After verification, the Spring Boot service is continuously delivered with a single click.
