Get Output from Azure DevOps Deploy to Kubernetes Task: A Guide for Data Scientists

Data scientists are increasingly leveraging the power of Kubernetes for managing their machine learning workloads. Azure DevOps, a suite of development tools, services, and features, provides a seamless way to deploy these workloads to Kubernetes. In this blog post, we’ll guide you on how to get output from the Azure DevOps Deploy to Kubernetes task.

Prerequisites

Before we dive in, ensure you have the following:

• An active Azure DevOps account
• A Kubernetes cluster
• Basic knowledge of Azure Pipelines and Kubernetes

Step 1: Setting Up Your Azure DevOps Pipeline

First, you need to set up your Azure DevOps pipeline. This pipeline will contain the Deploy to Kubernetes task.

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: Kubernetes@1
  inputs:
    connectionType: 'Kubernetes Service Connection'
    kubernetesServiceEndpoint: 'MyKubeServiceConnection'
    command: 'apply'
    useConfigurationFile: true
    configuration: 'deployment.yaml'

This YAML file defines a pipeline that triggers on any push to the master branch. It uses the Kubernetes task to apply a configuration from a file named deployment.yaml.

Step 2: Configuring the Kubernetes Deployment

The deployment.yaml file contains the configuration for your Kubernetes deployment. Here’s a simple example:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: my-app:1.0.0

This configuration deploys three replicas of an application named my-app.

Step 3: Getting Output from the Deploy Task

To get output from the Deploy to Kubernetes task, you can use the kubectl get command in a script task following the deployment task. This command retrieves the status of the deployed resources.

- script: |
    kubectl get deployment my-app -o json
  displayName: 'Get Deployment Status'

This script task retrieves the status of the my-app deployment in JSON format.

Step 4: Parsing the Output

The output from the kubectl get command is a JSON object that contains detailed information about the deployment. You can parse this output using tools like jq in a script task.

- script: |
    kubectl get deployment my-app -o json | jq '.status'
  displayName: 'Parse Deployment Status'

This script task retrieves the status of the my-app deployment and parses the output to extract the status field.

Conclusion

Getting output from the Azure DevOps Deploy to Kubernetes task is a straightforward process. It involves setting up an Azure DevOps pipeline, configuring a Kubernetes deployment, retrieving the status of the deployment, and parsing the output. This process provides valuable insights into your deployments, helping you manage your machine learning workloads more effectively.
