In this tutorial, I will be demonstrating to you on how you can use Azure DevOps from creating a pipeline to deploying an application to a Kubernetes cluster in Azure. I will be following the post "A DevOps journey using Azure DevOps" by Thomas Thornton.
We will be using the following for the lab:
- Setting up Azure DevOps Environment
- Deploy Resource using Terraform modules
- Deploy a simple test application to Azure AKS
- Using CI/CD to automate the deployment of the process
- Testing the creation of resources using automated testing such as Inspec
- Monitoring and setting up alerts using Application and Container Insights
- Setting up Azure DevOps Environment
In this setup, I will show you how to set up the Azure DevOps Environment and create the group required for AKS.
1.1 Azure DevOps Setup - This will set up the Azure DevOps Organisation Setup, Project Creation and create Service Principal.
- Creation of Blob Storage location for Terraform State file
- Create AD Group for AKS Admin Group
2.Setting up Azure DevOps Environment
This will create all of the Azure resources from the infrastructure in order to run and test applications.
2.1 Pipeline setup - Setting Azure DevOps Pipeline with creating the following resources
- Azure Container Registry
- Azure Virtual Network
- Azure Kubernetes Service
- Azure Log Analytics
3.Deploy Application to Azure Container Registry
3.1 Container Registry Set up This will set up image and deploy to container registry.
- Deploy a Application to Container Registry.
- Build the Docker Image Locally
- Run Docker Image Locally
- Deploy Application to Container Register
4.Deploy Application to Azure Kubernetes Cluster
3.1 AKS-Setup This will the Azure Kubernetes Services in Azure.
-
Add AKS ACR Role assignment- Terraform to add role assignment for AKS managed identity to access the deployed ACR
-
Add Application Insights to Terraform
-
Application Insights - monitor the application once deployed
-
Add Azure Key Vault to Terraform - store secrets used the Azure DevOps Variable Group.
-
Update Pipeline to Deploy Application to AKS
5.CI/CD Deploy-To-CICD- Pipeline Trigger for automatic pipeline runs and automated deployment of your AKS Application
6.Testing Azure Resourses Testing
- Inspec Testing using Azure DevOps Pipeline
- Run Inspec-Tests using Azure DevOps
- View Inspec reports in Azure DevOps
7.Monitoring and Alerting Montioring
- Using Application Insights to view telemetry data!
- Configure availability test using Application Insights
- Reviewing Log Analytics Container Insights
Tips (Please run the pipeline according to the labs in order).
- staging pipeline.yml
- staging validate.yml
- production-validate.yml
