# Tutorials
### Create & Test Docker Images
- `git clone https://github.com/Azure-Samples/azure-voting-app-redis.git`
- `cd azure-voting-app-redis`
- `docker-compose up -d`
- `docker images`
- `docker ps`
- Browse to [http://localhost:8080](http://localhost:8080)
- `docker-compose stop`
- `docker-compose down`
### Push Docker Images to Azure Container Registry (ACR)
- Install latest [Azure-CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-windows?view=azure-cli-latest)
- Need to use Powershell in admin mode to run below commands on Windows due to this [issue](https://github.com/Azure/azure-cli/issues/4843)
- `az group create --name akstrials --location eastus`
- `az acr create --resource-group akstrials --name jomitacr --sku Basic`
- `az acr login --name jomitacr -g akstrials`
- `az acr list --resource-group akstrials --query "[].{acrLoginServer:loginServer}" --output table`
- `docker images`
- `docker tag azure-vote-front jomitacr.azurecr.io/azure-vote-front:v1`
- `docker push jomitacr.azurecr.io/azure-vote-front:v1`
- `az acr repository list --name jomitacr -g akstrials --output table`
- `az acr repository show-tags --name jomitacr -g akstrials --repository azure-vote-front --output table`
### Create Azure Kubernetes Service Cluster
- `az provider register -n Microsoft.ContainerService`
- `az aks create -g akstrials -n jackaks --node-count 1 --generate-ssh-keys`
- Download `kubectl.exe` and set it in your path
- https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-binary-via-curl or
- `az aks install-cli`
- `az aks get-credentials -g akstrials --n jackaks`
- `kubectl get nodes`
#### Configure ACR permissions for AKS identity
`
- `$CLIENT_ID=$(az aks show -g akstrials --n jackaks --query "servicePrincipalProfile.clientId" --output tsv)`
- `$ACR_ID=$(az acr show -n jomitacr -g akstrials --query "id" --output tsv)`
- `az role assignment create --assignee $CLIENT_ID --role Reader --scope $ACR_ID`
#### Deploy Application on AKS
- Update `azure-vote-all-in-one-redis.yaml` file to use the image from ACR `line 47`
- `image: jomitacr.azurecr.io/azure-vote-front:v1`
- `kubectl create -f azure-vote-all-in-one-redis.yaml`
- `kubectl get service azure-vote-front --watch` (wait for EXTERNAL-IP)
- Browse `http://EXTERNAL-IP`
- `kubectl proxy` (to see the dashboard)
#### Scaling Nodes
- `az aks scale -n jackaks -g akstrials --node-count 3`
#### Scaling Pods
- `kubectl get pods`
- `kubectl scale --replicas=5 deployment/azure-vote-front`
- `kubectl get pods`
#### Autoscaling ([horizontal pod autoscaling](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/))
- `kubectl autoscale deployment azure-vote-front --cpu-percent=50 --min=3 --max=10`
- `kubectl get hpa`
#### Update Application
- `docker-compose up --build -d` (update application and rebuild the images)
- `az acr list -g akstrials --query "[].{acrLoginServer:loginServer}" --output table`
- `docker tag azure-vote-front jomitacr.azurecr.io/azure-vote-front:v2`
- `docker push jomitacr.azurecr.io/azure-vote-front:v2`
- `kubectl get pod`
- `kubectl set image deployment azure-vote-front azure-vote-front=jomitacr.azurecr.io/azure-vote-front:v2`
- `kubectl get service azure-vote-front`
#### Monitor and Log Analytics
- Setup [Container Monitoring solution in Log Analytics](https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-containers) using Azure Portal
- Copy the `` and ``
- `kubectl create secret generic omsagent-secret --from-literal=WSID=WORKSPACE_ID --from-literal=KEY=WORKSPACE_KEY`
- `kubectl create -f oms-daemonset.yaml`
- `kubectl get daemonset`
- Check the OMS Portal after few minutes to see the dashboard
#### Upgrade cluster
- `az aks get-upgrades -n jackaks -g akstrials --output table`
- `az aks upgrade -n jackaks -g akstrials --kubernetes-version 1.8.2`
- `az aks show -n jackaks -g akstrials --output table`
