Jenkins provides good support for providing continuous deployment and delivery. If you look at the flow of any software development through deployment, it will be as shown below.

Perform Continuous Deployment using Jenkins

The main part of Continuous deployment is to ensure that the entire process which is shown above is automated. Jenkins achieves all of this via various plugins, one of them being the “Deploy to container Plugin” which was seen within the earlier lessons.

There are plugins available which can actually give you a graphical representation of the Continuous deployment process. But first lets create another project in Jenkins, so that we can see best how this works.

Let’s create a simple project which emulates the QA stage, and does a test of the Helloworld application.

Step 1 − Go to the Jenkins dashboard and click on New Item. Choose a ‘Freestyle project’ and enter the project name as ‘QA’. Click on the Ok button to create the project.

Step 2 − In this example, we are keeping it simple and just using this project to execute a test program for the Helloworld application.

So our project QA is now setup. You can do a build to see if it builds properly.

Step 3 − Now go to you Helloworld project and click on the Configure option

Step 4 − Within the project configuration, choose the ‘Add post-build action’ and choose ‘Build other projects’

Step 5 − Within the ‘Project to build’ section, enter QA as the project name to build. You can leave the option as default of ‘Trigger only if build is stable’. Click on the Save button.

Step 6 − Build the Helloworld project. Now if you see the Console output, you’ll also see that after the Helloworld project is successfully built, the build of the QA project will also happen.

Step 7 − Let now install the Delivery pipeline plugin. Go to Manage Jenkins → Manage Plugin’s. Within the available tab, search for ‘Delivery Pipeline Plugin’. Click On Install without Restart. Once done, restart the Jenkins instance.

Step 8 − To see the Delivery pipeline in action, within the Jenkins Dashboard, click on the + symbol within the Tab next to the ‘All’ Tab.

Step 9 − Enter any name for the View name and choose the option ‘Delivery Pipeline View’.

Step 10 − Within the next screen, you can leave the default options. One can change the subsequent settings −

• Ensure the option ‘Show static analysis results’ is checked.
• Ensure the option ‘Show total build time’ is checked.
• For the Initial job – Enter the Helloworld project as the first job which should build.
• Enter any name for the Pipeline
• Click the OK button.

You’ll now see a great view of the entire delivery pipeline and you’ll be able to see the status of each project within the entire pipeline.

Another famous plugin is the build pipeline plugin. Let’s take a look at this.

Step 1 − Go to Manage Jenkins → Manage Plugin’s. Within the available tab, search for ‘Build Pipeline Plugin’. Click On Install without Restart. Once done, restart the Jenkins instance.

Step 2 − To see the Build pipeline in action, within the Jenkins Dashboard, click on the + symbol within the Tab next to the ‘All’ Tab.

Step 3 − Enter any name for the View name and choose the option ‘Build Pipeline View’.

Step 4 − Accept the default settings, just within the Selected Initial job, ensure to enter the name of the Helloworld project. Click on the Ok button.

You’ll now see a great view of the entire delivery pipeline and you’ll be able to see the status of each project within the entire pipeline.
