How can Jenkins execute Docker commands?

To run Docker commands in Jenkins, you can follow these steps:

1. Install Docker on the Jenkins server: Make sure Docker is already installed on the Jenkins server and the Jenkins user has permission to access Docker services.
2. Install the Docker plugin in Jenkins: Install the Docker plugin in the Jenkins plugin management page so that you can run Docker commands in Jenkins.
3. Configure Docker: In the global configuration of Jenkins, add the path of Docker and other relevant configuration information so that Jenkins can correctly use Docker services.
4. Create a new Jenkins Job: Create a new Job in Jenkins and add an “Execute shell” step in the build section.
5. Write Docker commands: Write the Docker commands to be executed in the “Execute shell” step, such as building images, running containers, etc.
6. Save and create Job: Save the configuration of the Job and trigger the build. Jenkins will execute the Docker commands you have written.

By following the steps above, you can execute Docker commands in Jenkins to build and manage Docker containers.
