See Jenkins.
As we expect a new Jenkins Master to come with a pre-defined list of plugins, we have this derived image. The list of plugins can be found in plugins.txt.
If you're unsure which plugins you really want, you can create a clean Jenkins 2 container. Then install the plugins you want and use the get-plugins.sh script to generate the plugins.txt file yourself.
You can then use the plugin-list-to-install-command.sh to transform it into the new style of plugin installation.
