Build containerized application using Docker and Azure.pdf
This document outlines the process of building containerized applications using Docker and Azure, detailing microservices architecture, Docker containers and images, and development environment setup. Key topics include Dockerfile creation, Azure container services like Azure Kubernetes Service, and deployment steps using the Azure CLI. The document also covers best practices for optimizing container builds and deploying applications on various Azure services.

Overview Docker containerand image Docker Container ● Virtualized runtime environment used in application development. ● Can use just one machine, share its kernel and virtualize the OS to run more isolated processes. ● Docker containers are lightweight. Docker Images ● Snapshot in other types of VM environments. ● Record of a Docker container at a specific point in time. ● Image can’t be changed, it can be duplicated, shared, or deleted.

Prerequisites • Install DockerDesktop it is free, it is available for Mac and Windows. • Docker Hub account, it is free. • Install Visual Studio 2019 or 2022 or Visual Studio Code. • Azure account where we are able to create an azure container registry • PowerShell in Windows or Azure Cloud Shell. • If you are using Visual Studio Code, Microsoft C# for Visual Studio Code, Docker and Azure App Service extensions must be installed.

Build and storeimages by using Azure Container Registry • What is Container Registry? • Azure service that you can use to create your own private Docker registries. • Similar to Docker Hub but offers a few unique benefits: Container Registry runs in Azure, Container Registry is highly scalable, providing enhanced throughput for Docker pulls that can span many nodes concurrently. • Use Container Registry • Create a registry by using either the Azure portal or the Azure CLI. • Store and host images, and build images.

Deploy an AzureKubernetes Service cluster and run an application using the Azure CLI 1- Open CloudShell My Dashboard — Microsoft Azure and connect to your cluster as bellow: az account set — subscription yoursubscription az aks get-credentials — resource-group aksgr — name myAKSCluster You can find these commands when you open Azure Portal and your cluster:

- 29. Deploy an AzureKubernetes Service cluster and run an application using the Azure CLI 4- Run the application and deploy it in the cluster using the kubectl apply command and specify the name of your YAML manifest. kubectl apply -f azure-demo-deployment.yaml We will use kubectl get deployments to verify if the deployment was created or not. When the application runs, a Kubernetes service exposes the application front end to the internet. This process can take a few minutes to complete. 5- we will use kubectl get service command with the --watch argument. kubectl get service demo-kubernetes-deployment — watch

- 31. Azure Container App AzureContainer Apps is a fully managed environment that enables you to run microservices and containerized applications on a serverless platform. • Provide a serverless hosting service that sits on top of an AKS Service • Deploy multiple containers • Azure Container app do not even expose Kubernetes APIs to the users.
