Deploying a Spring Application with Jenkins, GitLab, Docker Compose, and Maven

[root@hd03 ~]# docker-compose -f /root/docker-compose.yml up -d

To view the Jenkins admin password, navigate to the secrets directory and display the initialAdminPassword file: [root@hd03 secrets]# pwd /data/jenkins/secrets [root@hd03 secrets]# cat initialAdminPassword 337699819bc745ae80d155654dcc59b7

System Configuration

During installation, select the following plugins under System Management → Plugin Management → Optional Plugins → Deploy to container:

1. Deploy to container

2. Maven Integration

3. Publish Over SSH

4. SSH (including SSH server plugin to push the built JAR to a remote server)

5. Install ansible

Modify the GitLab host entry from [email protected] to the actual IP address: [root@hd03 etc]# pwd /data/gitlab-rails/etc

Update the host configuration accordingly.

1. Generate a GitLab Access Token

In GitLab, go to Settings → Access Tokens and create a new token.

Configure the GitLab connection in Jenkins using the generated token.

1) Deploy the Spring Project

1. Upload the project to GitLab

2. Build a Maven project

3. Configure Git

4. Set up a build trigger (pom.xml)

In pom.xml use the command: clean package -e -U -Dmaven.test.skip=true 5. Execute the build

The test did not publish successfully.

Inspect the build output directory: [root@hd03 target]# pwd /data/jenkins/workspace/xiang/target [root@hd03 target]# ll drwxr-xr-x 3 root root 47 Feb 10 11:42 classes

-rw-r--r-- 1 root root 16102407 Feb 10 11:42 demo-0.0.1-SNAPSHOT.jar

-rw-r--r-- 1 root root 2937 Feb 10 11:42 demo-0.0.1-SNAPSHOT.jar.original

... (additional file listings) ...

At this point, the Spring project has been successfully deployed.
