Kubernetes is an open-source container orchestration platform that is used to manage and automate the deployment, scaling, and management of containerized applications. Azure DevOps is a cloud-based DevOps service that provides a complete CI/CD pipeline for building, testing, and deploying applications. In this article, I will discuss how to deploy a Kubernetes application using Azure DevOps.

Prerequisites

  • An Azure subscription
  • An Azure DevOps account
  • A Kubernetes cluster
  • A Docker image

Step 1: Create a Kubernetes Deployment File

Create a Kubernetes deployment file (deployment.yaml) in your source code repository. This file should contain the specifications of your Kubernetes deployment, including the container image, replicas, and ports. Here is an example of a deployment file:

Kubernetes deployment file

YAML
 
apiVersion: apps/v1

kind: Deployment

metadata:

  name: my-app-deployment

spec:

  replicas: 3

  selector:

    matchLabels:

      app: my-app

  template:

    metadata:

      labels:

        app: my-app

    spec:

      containers:

      - name: my-app-container

        image: my-app-image:latest

        ports:

        - containerPort: 8080


Step 2: Create an Azure DevOps Pipeline

In your Azure DevOps account, create a new pipeline and select the source code repository where your deployment file is located. Choose the appropriate repository type (e.g., Git) and select the branch to use for the deployment.

Next, choose the appropriate template for your pipeline. For Kubernetes deployments, we can use the “Deploy to Kubernetes” template, which is available in the Azure DevOps marketplace.

Step 3: Configure the Azure Kubernetes Service (AKS) Connection

In the pipeline, add a new task for configuring the AKS connection. This task will authenticate your pipeline to your AKS cluster. To add this task, search for “Kubernetes” in the task search bar and select the “Configure Kubernetes connection” task.

In the task configuration window, select the appropriate Azure subscription and AKS cluster. Also, provide the Kubernetes namespace and service account information.

Step 4: Add the Kubernetes Deployment Task

After configuring the AKS connection, add the Kubernetes deployment task. Search for “Kubernetes” in the task search bar and select the “Deploy to Kubernetes” task.

In the task configuration window, provide the path to your deployment file, select the appropriate image registry, and provide the container image name and tag.

Step 5: Save and Run the Pipeline

Save your pipeline and run it. The pipeline will build the Docker image, push it to the image registry, and deploy it to the Kubernetes cluster.

Conclusion

Kubernetes is a powerful tool for managing containerized applications. Azure DevOps provides a complete CI/CD pipeline for building, testing, and deploying applications. By using these tools together, we can easily deploy applications to Kubernetes clusters. With Azure DevOps, you can automate your deployment process and reduce manual errors, which can improve your application’s reliability and scalability.

We covered the steps for creating a Kubernetes deployment file, creating an Azure DevOps pipeline, configuring the AKS connection, adding the Kubernetes deployment task, and running the pipeline. By following these steps, you can deploy your Kubernetes application using Azure DevOps.

Kubernetes has become the de facto standard for container orchestration and management and with good reason. It is highly scalable, portable, and resilient, making it a great choice for deploying and managing containerized applications.
