Deploy Applications to Red Hat OpenShift Using Microsoft Azure DevOps Pipeline

Simple steps

In this blog, we’ll go through all the steps in setting up a pipeline using MS Azure DevOps to deploy an application on Red Hat OpeShift.

Prerequisites

• GitHub account
• Azure Subscription
• Red Had OpenShift cluster

Steps

Step#1: Create Azure DevOps Organization

The Organization is used to store your projects and manage access to data. Access Azure Pipelines page and click on start free, and follow the its steps. Write your organization name, in my case BashayrAlabdullah 😬

Step#2: Create project

Step#3: Install OpenShift extension

From the marketplace here click on Get it free , install to the organization

Step#4: Create service connection

To connects Microsoft Azure DevOps to your OpenShift cluster, you need to configure the OpenShift service connection.

1. Click on Project settings
2. Select Service Connections
3. Select OpenShift

Select the authentication method you want: Basic, Token or No authentication

Step#5: Create the pipeline

Let’s go now to the pipelines

and click on Create Pipeline . My code on GitHub, I chose GitHub

Then, Authorize Azure Pipelines. You’ll be prompted to choose a repository.

After your connection to GitHub has been authorized, configure your pipeline and select Starter pipeline

Click on Show assistant to

Search and select Execute oc command OC

and the click on Add . Repeat the steps for the following commands:

oc new-app https://github.com/Bashayr29/simple-app.git
oc expose svc simple-app
oc start-build simple-app --follow
oc status

the final pipeline

Save and run the pipeline

Access the job and watch it 😍

The job status is success 🎁

Step#6: Check the deployment on your OpenShift cluster

echo "http://$(oc get route simple-app -o jsonpath='{.spec.host}')"

Now, let’s have fun and commit some changes to the repo. I want to change the message from Hi there! to Hi there!, from Azure DevOps and then push this change to the main branch.

The job status is running 🏃‍♀ wait till the job is done

refresh the page

yaaa! Now every time the pipeline is triggered, a new build starts, and our application is pushed to the cluster.

And that’s all folks. Thank you for reading💛 ❤️

Bye!
