Managing Jenkins
|
This site is the new docs site currently being tested. For the actual docs in use please go to https://www.jenkins.io/doc. |
Most standard administrative tasks can be performed from the screens in the Manage Jenkins section of the dashboard. In this chapter, we look at these screens and explain how to use them.
The tiles displayed on the Manage Jenkins page are grouped logically. Here we discuss the pages that are part of the standard installation. Plugins may add pages to this screen.
The top of the Manage Jenkins screen may contain "Monitors" that alert you when a new version of the Jenkins software or a security update is available. Each monitor includes a description of the issue it is reporting and links to additional information about the issue
Inline help is available on most Manage Jenkins pages:
-
To access the help, select the
?icon to the right of each field. -
Click the
?icon again to hide the help text.
Other system administration topics are discussed in Jenkins System Administration.

Configure your Jenkins instance using a human-readable YAML file rather than the UI. This is an optional feature that appears in this group only when the plugin is installed on your controller.

Tools and Actions group
Screens for common management tasks and management tools that enable you to do administrative tasks without using the UI.
- Reload Configuration from Disk
-
Discard all data that is loaded in memory and reload everything from the file system. This is useful when you modify configuration files directly on disk.
- Jenkins CLI

How to use the Jenkins CLI from a shell or script.

- Prepare for Shutdown
-
Prevents new builds from starting so that the system can be shut down safely. Displays a red banner with a custom message so that users know what is about to happen.
This does not ask Jenkins to stop; this action will just prevent new builds from starting.
If you need to stop or restart Jenkins, you should use the command line or the /restart and /safeRestart end points.
There is also a plugin called Safe Restart that will add a Restart Safely link in the UI.
