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

This article demonstrates how to create a complete Jenkins + Docker + Spring Boot one‑click automated deployment on a CentOS 7 host.

1. Install Docker

Update the system and remove any old Docker packages, then install the required utilities and Docker CE:

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 (Blue Ocean) in a Docker container, exposing ports 8080 and 50000:

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 Jenkins at http://{SERVER_IP}:8080 , then unlock it by retrieving the initial admin password:

docker exec -it {JENKINS_CONTAINER} bash

cat /var/lib/jenkins/secrets/initialAdminPassword

Install the recommended plugins, then add Maven Integration, Publish Over SSH (optional), and Gitee plugin if using Gitee.

3. System Configuration

Configure Maven under Manage Jenkins → Global Tool Configuration and set the Maven installation path.

4. Create a Jenkins Job

Create a new freestyle project, configure the Git repository URL and credentials, and add a build step that runs Maven:

clean install -Dmaven.test.skip=true

Save the job.

5. Test the Build

Trigger a build, monitor the console output, and verify that a JAR file is produced.

6. Dockerfile for the Spring Boot Application

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"]

7. Jenkins Job – Build and Run 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

After the job finishes, verify the container is running with docker ps and check its logs with docker logs zx-order . Access the application at http://{SERVER_IP}:8888 .
