One‑Click Jenkins + Docker + SpringBoot Automated Deployment Guide

The article describes a complete, step‑by‑step process for achieving one‑click automated deployment of a SpringBoot application using Jenkins, Docker, and Maven on a CentOS 7 host.

Environment

CentOS 7 with Git (Gitee) is used as the base system.

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   # install the latest stable version
systemctl start docker
systemctl enable docker
docker version   # verify installation

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 Jenkins at http://{host‑ip}:8080, unlock it using the password from cat /var/lib/jenkins/secrets/initialAdminPassword, install the recommended plugins, and create an admin user.

System Configuration

Install required plugins such as Maven Integration, Publish Over SSH, and Gitee (if needed). Configure Maven under Manage Jenkins → Global Tool Configuration .

Create a Job

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

Testing the Build

Trigger a build, monitor the console output, and ensure the JAR is produced.

Dockerfile for the SpringBoot App

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

Jenkins Job Configuration for Docker

After the Maven build, add shell steps to build and run the 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

Save the configuration.

Final Build and Verification

Run the Jenkins job, then verify the container is running with docker ps and view logs via docker logs {container‑name}. Access the application in a browser at http://{host‑ip}:8888 to confirm successful deployment.
