Usage

1. Clone this repository to your local machine:

   git clone git@github.com:dcfrancisco/personal-cicd-server.git

2. Navigate to the cloned directory:

   cd personal-cicd-server

3. Start the containers using Docker Compose:

   docker-compose up -d

   This command will download the required Docker images and start the Jenkins and Nexus containers in the background.

4. Access Jenkins:

   Open your web browser and visit http://localhost:8080. This will take you to the Jenkins web interface.

Initial setup is required to unlock Jenkins and install the recommended plugins. To do this, you need to retrieve the initial admin password from the Jenkins container. You can do this by running the following command:

docker exec jenkins-instance cat /var/jenkins_home/secrets/initialAdminPassword

or

This may also be found at: /var/jenkins_home/secrets/initialAdminPassword

1. Access Nexus:

   Open your web browser and visit http://localhost:8081. This will take you to the Nexus web interface.

   /nexus-data/admin.password
   

2. Perform any additional configurations or setups required for Jenkins and Nexus as per your needs.

3. When you're finished, stop the containers using Docker Compose:

   docker-compose down

   This command will stop and remove the containers, but preserve the Jenkins data volume for future use.

Configuration

The Docker Compose configuration consists of two services: Jenkins and Nexus. Each service is defined with its own set of configurations.

Jenkins

• Docker image: Built using the ./jenkins context
• Container name: jenkins-instance
• Ports:
  • Jenkins web interface: 8080 (mapped to the host machine)
• Volumes:
  • jenkins-data: Stores Jenkins configuration and data

Nexus

• Docker image: Built using the ./nexus context
• Container name: nexus-instance
• Exposed ports: 8081, 8082, 8083
• Ports:
  • Nexus web interface: 8081 (mapped to the host machine)
• Volumes:
  • ./volume:/nexus-data: Stores Nexus configuration and data

Volumes

• jenkins-data: A named volume used by the Jenkins service to persist configuration and data. This volume is created automatically by Docker Compose.

Additional Information

• Both Jenkins and Nexus containers are set to automatically restart (restart: always) in case of any failures or system restarts.

Feel free to modify the configurations as per your requirements. For more information and advanced usage of Docker Compose, refer to the official documentation.
