This contains my demo for the MLSA Azure Episodes.

In the demo, I will walk through the following:

• creating a docker image,
• pushing the image to Azure Container Registry
• deploying the image to Azure Kubernetes serices.

Steps

• Test the app locally

$ python main.py

• Create a Docker image

$ docker login
$ docker build -t hub-username/image-name .

• Push the image to Azure Container Registry

$ az group create --name myResourceGroup --location eastus
$ az acr create --resource-group myResourceGroup --name <acrName> --sku Basic
$ az acr login --name <acrName>
$ docker tag docker-image:tag <acrLoginServer>/image-name:tag
$ docker images
$ docker push <acrLoginServer>/image-name:tag

• Get your image name and tag

$ az acr repository list --name <ACRname>    
$ az acr repository show-tags --name <ACRname> --repository <repo> --output table

Connect to the AKS CLI

Guide

$ az aks install-cli
$ az account set --subscription xxxx-xxx-xx-xx-xxxx
$ az aks get-credentials --resource-group myResourceGroup --name myAKSCluster
$ kubectl get nodes

• Create a K8s cluster and deployment files.

Create Deployments

$ kubectl apply -f aks/demo-ip.yml
$ kubectl apply -f aks/demo-service.yml

Test the application

$ kubectl get service

Navigate to the IP provided under External-IP

Debugging

$ kubectl get pods
$ kubectl get logs <pod-name>
$ kubectl describe pod <pod-name>
$ kubectl describe service <service-name>
$ kubectl describe deployment <deployment>

Clean up

$ az group delete --name myResourceGroup --yes --no-wait
