4.9. Configuring Blue Ocean with Jenkins
The Blue Ocean plugin and all its other dependent plugins (which form the Blue Ocean "suite of plugins") are not installed by default.
To install the Blue Ocean suite of plugins to your Jenkins instance:
If required, ensure you are logged in to Jenkins (as a user with the Administer permission).
From the Jenkins home page (i.e. the Dashboard of the Jenkins classic UI), click Manage Jenkins on the left and then Manage Plugins in the center.
Click the Available tab and type blue ocean into the Filter text box, which filters the list of plugins to those whose name and/or description contains the words "blue" and "ocean".
Select the Blue Ocean plugin’s check box near the top of the Install column and then click either the Download now and install after restart button (recommended) or the Install without restart button at the end of the page.
