Sophisticated visualization of CD pipelines

Blue Ocean provides a clear and intuitive view of your CD pipelines, allowing you to see the status, progress, and results of each stage and step. You can also see the changes, commits, and pull requests associated with each pipeline run, as well as the logs, artifacts, and tests. Blue Ocean makes it easy to spot issues and intervene when needed, as well as to monitor the performance and quality of your software delivery. Pipeline editor for easy automation

Blue Ocean makes it easy to create and edit pipelines as code, by guiding you through a visual process to generate a Jenkinsfile. A Jenkinsfile is a text file that defines your pipeline configuration using a declarative syntax. You can then commit your Jenkinsfile to your source control repository, where it can be versioned, reviewed, and triggered automatically. Blue Ocean also provides a Pipeline syntax snippet generator that helps you define pipeline steps with their arguments. Personalization and precision for DevOps teams

Blue Ocean allows you to customize your Jenkins UI to suit your role-based needs. You can choose which pipelines to display on your dashboard, filter them by branch or pull request, and pin your favorites for quick access. You can also switch between different views of your pipelines, such as the branch view, the pull request view, or the classic view. Blue Ocean also gives you pinpoint precision when intervention is needed or issues arise, by showing you where in the pipeline attention is needed, facilitating exception handling and increasing productivity.

Installing Blue Ocean on Jenkins is easy and straightforward. You can install it using one of the following methods: On an existing Jenkins instance

If you already have a Jenkins instance running on your platform, you can install Blue Ocean as a suite of plugins from the Jenkins Update Center. To do so, follow these steps:

• Login to your Jenkins server as a user with the Administer permission.

• From the Jenkins home page, select Manage Jenkins on the left and then Plugins.

• Select the Available tab and enter blue ocean in the Filter text box.

• Select the box to the left of Blue Ocean, and then select either the Download now and install after restart option (recommended) or the Install without restart option at the bottom of the page.

• The main Blue Ocean plugin automatically selects and installs all dependent plugins, composing the Blue Ocean suite of plugins.

• If you select the Install without restart option, you must restart Jenkins to gain full Blue Ocean functionality.

As part of Jenkins in Docker

If you want to run Jenkins and Blue Ocean in a Docker container, you can use the official Jenkins Docker image, jenkins/jenkins, which is available from the Docker Hub repository. This image does not include Blue Ocean by default, but you can install it as part of the setup wizard. To do so, follow these steps:

• Run the Jenkins Docker image with the following command:

docker run \ -u root \ --rm \ -d \ -p 8080:8080 \ -p 50000:50000 \ -v jenkins-data:/var/jenkins_home \ -v /var/run/docker.sock:/var/run/docker.sock \ jenkins/jenkins

• This command will download the image if necessary, and start a detached container with Jenkins running on port 8080. It will also mount a named volume called jenkins-data to persist the Jenkins data, and bind the host's Docker socket to allow Jenkins to communicate with the Docker daemon.

• Open your browser and go to to access the Jenkins web interface.

• Follow the setup wizard to unlock Jenkins and install the suggested plugins. You can also select the option to select plugins to install, and choose Blue Ocean from the list.

• After the installation is complete, create an admin user and password, and then you will see the Jenkins dashboard.
