Jenkins Blue Ocean is a modern user interface (UI) extension for Jenkins that provides an enhanced and user-friendly experience for visualizing, editing, and managing Continuous Integration/Continuous Deployment (CI/CD) pipelines. It aims to make it easier for both developers and non-developers to work with Jenkins pipelines. Here are some key features and concepts related to Jenkins Blue Ocean:
Visual Pipeline Editor: Blue Ocean offers a visual pipeline editor that allows you to create and edit Jenkins pipelines using a graphical interface. This makes it easier to design and understand complex pipeline workflows.
Pipeline Visualization: Pipelines are displayed as a series of interconnected steps and stages, providing a clear and intuitive view of the CI/CD process. You can see the status of each stage and easily identify any issues.
Personalization: Blue Ocean provides a personalized dashboard where users can organize and view their favorite pipelines. It allows you to customize your dashboard to display the pipelines that matter most to you.
Integrated Code Repository: Blue Ocean integrates with popular version control systems like Git and provides a seamless experience for configuring and running pipelines based on code changes.
Real-time Feedback: The UI provides real-time feedback on pipeline execution, showing progress, test results, and logs as they happen.
Parallel and Sequential Execution: You can define parallel and sequential execution of pipeline stages, making it easy to optimize your CI/CD workflows.
GitHub Integration: Blue Ocean has built-in integration with GitHub, making it simple to trigger pipelines based on GitHub events, such as code pushes or pull requests.
Extensible: Jenkins Blue Ocean is extensible, allowing you to create custom pipeline templates and integrations to suit your specific needs.
Lets get started with Jenkins Installation and setting up blue ocean:
Create an EC2 instance in AWS or you may go for other cloud as well as we are going to install and run jenkins in VM.
Now make a connection to this VM using ssh,
Note down the below commands to install Jenkins,
sudo apt-get update -y sudo apt install fontconfig openjdk-17-jre # as java is the pre-requisite to run jenkins java -version curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2023.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list > /dev/null sudo apt update -y sudo apt install Jenkins -yNow open 8080 port of your VM
Copy the VM public ip and paste it in URL in the below format,
https://<Public_IP>:8080/
Copy the above path and cat it in the terminal to find the password and click on continue,
We need to install Blue ocean theme now.
Go to
Manage Jenkins > Plugins > Available Plugins > Type "Blue Ocean" > Install
Now Blue Ocean is installed. Click on blue ocean logo from jenkin's dashboard
or type url in below format to use Jenkins blue,
https://<VM_PublicIP>:8080/blue/Now we need to choose one of the repository and need to create access token.
Creating access token in github,
github repo > your profile > Click on your profile place right top corner > Settings > Developer Settings > Tokens(classic) > Generate new token
Now paste the token in jenkins where it is asking for access token.
It will then display your github profile and then the projects in the repository.
I have chosen a project with No Jenkinsfile
Jenkins automatically detected that i don't have jenkinsfile in my project and asked to create a pipeline using UI
. And then jenkins will create the jenkinsfile into my project.
Now below screenshot the jenkinsfile is created,
Now after clicking on build we can download the build log as well.
