jenkinsci/docker — reverse-engineered prompt

Build me a Docker based Jenkins setup that I can run locally without having to remember all the commands.

I want it to start a working Jenkins server, keep all Jenkins data safe in a Docker volume, expose the normal web port, support connecting build agents, and make it easy to see the first admin password after startup. Please include simple scripts or commands for starting, stopping, viewing logs, and backing up the Jenkins home data.

Also add a short README for a beginner that explains how to open Jenkins in the browser, finish the first setup wizard, where the data is stored, and what to do if Jenkins says it appears to be offline because of DNS. Keep it practical and don’t overcomplicate it. Use the official Jenkins Docker image with the current LTS JDK version, and look up current docs online if you need to.
