Install Blue Ocean Plugin in Jenkins

A Blue Ocean is a new user experience for Jenkins and provides an interactive view for Jenkins Pipeline and jobs. it reduces the clutter and increases the clarity.

Blue Ocean is simple to install and will work on basically any Jenkins 2 instance (version 2.7 or later). Even better, it runs side-by-side with the existing Jenkins web UI - you can switch back and forth between them whenever you like. There’s really no risk.

Install Blue Ocean

1. Login to your Jenkins server

2. Click Manage Jenkins in the sidebar then Manage Plugins

3. Choose the Available tab and use the search bar to find Blue Ocean.
4. Click the checkbox in the Install column.
5. Click either Install without restart or Download now and install after restart.

After you install Blue Ocean, you can start using it by clicking on Open Blue Ocean in the Side Bar of the Jenkins web UI.

Alternatively, you can access Blue Ocean directly by appending /blue to the end of your Jenkins server’s URL - e.g. http://jenkins-server-url/blue

Switching to the classic UI

Blue Ocean does not support some legacy or administrative features of Jenkins that are necessary for some users.

If you need to leave the Blue Ocean user experience to access these features, click the Go to the classic icon at the top of a common section of Blue Ocean’s navigation bar.

Clicking this button takes you to the equivalent page in the Jenkins classic UI or the most relevant classic UI page that parallels the current page in Blue Ocean.
