Run AmazonLinux on Azure

Checkout Azure AmazonLinux Demo

git clone https://github.com/listonb/azure-amazonlinux-demo.git
cd azure-amazonlinux-demo

Set reusable environment variables

export RESOURCE_GROUP=amazonlinuxdemo
export LOCATION=eastus
export CLUSTER_NAME=amazonlinux
export DNS_PREFIX=$CLUSTER_NAME

Create resource group to contain demo

az group create -l $LOCATION --name $RESOURCE_GROUP

Create Azure Container Registry to store images

az acr create --resource-group $RESOURCE_GROUP --name $CLUSTER_NAME --sku Basic --admin-enabled true

Docker Login to the new Azure container Registry

az acr credential show --name $CLUSTER_NAME --query "join(' ', ['docker login $CLUSTER_NAME.azurecr.io -u $CLUSTER_NAME', '-p', passwords[0].value])" -o tsv | sh

Create Azure Container Service with Kubernetes orchestrator

az acs create --orchestrator-type=kubernetes --resource-group $RESOURCE_GROUP --name=$CLUSTER_NAME --dns-prefix=$DNS_PREFIX --generate-ssh-keys

Install the Kubernetes CLI if you don't have it

az acs kubernetes install-cli

Login to Kubernetes cluster

az acs kubernetes get-credentials --resource-group=$RESOURCE_GROUP --name=$CLUSTER_NAME

See existing nodes

kubectl get nodes

Build docker container that has basic HTTP server written in go outputing the contents of /etc/system-release

docker build . -t azure-amazon-linux

Tag the built image to our Azure Container Registry

docker tag azure-amazon-linux $CLUSTER_NAME.azurecr.io/azure-amazon-linux:latest

Push the new image to Azure Container Registry for use in the Kubernetes Cluster

docker push $CLUSTER_NAME.azurecr.io/azure-amazon-linux:latest

See docker images

docker images

Run the AmazonLinux Container

kubectl run $CLUSTER_NAME --replicas=2 --image $CLUSTER_NAME.azurecr.io/azure-amazon-linux --port=80

See Deployment

kubectl describe deployment $CLUSTER_NAME

Expose a Load balancer to the Kubernetes nodes running our image

kubectl expose deployments $CLUSTER_NAME --port=80 --type=LoadBalancer

Look for the external IP Assigned to the Service

kubectl get svc $CLUSTER_NAME

Scale Azure Container Service

az acs scale --name $CLUSTER_NAME --resource-group $RESOURCE_GROUP --new-agent-count 6

See new nodes

kubectl get nodes

Scale Kubernetes Deployment

kubectl scale --replicas=6 deployment/$CLUSTER_NAME

See Deployment

kubectl describe deployment $CLUSTER_NAME
