1. Install Docker
If you don't have Docker installed on your machine, refer to Docker's official website (https://www.docker.com/get-started) to download and install Docker.
2. Install Jenkins
Similarly, if you don't have Jenkins installed, visit Jenkins' official website (https://www.jenkins.io/download/) to download and install Jenkins on your machine.
3. Configure Jenkins
Once Jenkins is installed, open your web browser and navigate to http://localhost:8080 to access the Jenkins web interface. Follow the instructions to set up Jenkins, including creating an admin user and installing recommended plugins.
4. Install Docker plugin
Go to the Jenkins dashboard, click on "Manage Jenkins" on the left side menu, and then click on "Manage Plugins." In the "Available" tab, search for "Docker" and install the "Docker plugin." Restart Jenkins if prompted.
5. Configure Docker Cloud
After installing the Docker plugin, go back to the Jenkins dashboard and click on "Manage Jenkins" again. This time, select "Configure System." Scroll down to the "Cloud" section and click on "Add a new cloud." Choose "Docker" from the dropdown menu, provide a name for your Docker configuration, and configure Docker settings as per your environment (e.g., Docker URL and credentials).
6. Create a Jenkins job
To build and run your project using Docker, create a new Jenkins job. Go to the Jenkins dashboard and click on "New Item." Provide a name for the job, select the job type (e.g., freestyle project), and click on "OK." In the job configuration page, scroll down to the "Build" section and click on "Add build step." Choose "Execute shell" or any other build step according to your project requirements.
7. Use Docker commands in Jenkins job
In the build step, you can use Docker commands inside shell scripts to build, run, and manage containers. For example, you can use the "docker build" command to build a Docker image, "docker run" command to start a container, and so on. Refer to Docker's documentation (https://docs.docker.com/) for detailed usage instructions.
8. Save and run the job
Once you have configured the build step for your Jenkins job, click on "Save" to save the job configuration. Then, click on "Build Now" to trigger a build. Jenkins will execute the build steps, including Docker commands, as defined in your job configuration.
This is a basic guide to get started with Jenkins and Docker integration. There are more advanced features and approaches available, such as using Docker agents, Docker Compose, Docker-based Jenkins pipeline, etc. You can explore these options as per your project requirements and learn more from Jenkins' official documentation (https://www.jenkins.io/doc/) and Docker's documentation (https://docs.docker.com/).
