Get acs-engine

Download latest release from https://github.com/Azure/acs-engine/releases/tag/v0.26.2

wget https://github.com/Azure/acs-engine/releases/download/v0.26.2/acs-engine-v0.26.2-darwin-amd64.tar.gz
tar -zxvf acs-engine-v0.26.2-darwin-amd64.tar.gz
cd acs-engine-v0.26.2-darwin-amd64

create mixed cluster

set variables

KUBE_GROUP="dz-win-1709-L"
KUBE_NAME="dz-win-1709-L"
LOCATION="westeurope"

create resource group

az group create -n $KUBE_GROUP -l $LOCATION

get one of the sample templates from https://github.com/Azure/acs-engine/tree/master/examples/windows or use these ones https://github.com/denniszielke/container_demos/blob/master/aks-engine/acsengvnet-win-1809.json https://github.com/denniszielke/container_demos/blob/master/aks-engine/acsengvnet-win-1803.json

make sure to set the variables for SERVICE_PRINCIPAL_ID, SERVICE_PRINCIPAL_SECRET and YOUR_SSH_KEY with your own values

create arm template by using the acs-engine json

./acs-engine generate acseng-1709-L.json

deploy arm template

az group deployment create \
    --name $KUBE_NAME \
    --resource-group $KUBE_GROUP \
    --template-file "_output/$KUBE_NAME/azuredeploy.json" \
    --parameters "_output/$KUBE_NAME/azuredeploy.parameters.json"

set the kubeconfig

export KUBECONFIG=`pwd`/_output/$KUBE_NAME/kubeconfig/kubeconfig.westeurope.json

check nodes

kubectl get node -l beta.kubernetes.io/os=windows -o wide
kubectl get node -l beta.kubernetes.io/os=linux -o wide

kubectl create secret docker-registry mobileregistry --docker-server $REGISTRY_URL --docker-username $REGISTRY_NAME --docker-password $REGISTRY_PASSWORD --docker-email '[email protected]'

Creating storage for the file share

https://github.com/andyzhangx/demo/tree/master/windows

AKS_STORAGE_ACCOUNT_NAME=
AKS_STORAGE_RESOURCE_GROUP=
AKS_STORAGE_KEY=
LOCATION=westeurope

create storage account

az storage account create --resource-group $AKS_STORAGE_RESOURCE_GROUP --name $AKS_STORAGE_ACCOUNT_NAME --location $LOCATION --sku Standard_LRS

AKS_STORAGE_KEY=$(az storage account keys list --account-name $AKS_STORAGE_ACCOUNT_NAME --resource-group $AKS_STORAGE_RESOURCE_GROUP --query "[0].value")

az storage share create -n www-content --quota 10 --account-name $AKS_STORAGE_ACCOUNT_NAME --account-key $AKS_STORAGE_KEY

az storage share create -n www-configuration --quota 10 --account-name $AKS_STORAGE_ACCOUNT_NAME --account-key $AKS_STORAGE_KEY

az storage share create -n publicweb-content --quota 10 --account-name $AKS_STORAGE_ACCOUNT_NAME --account-key $AKS_STORAGE_KEY

kubectl create secret generic azure-secret --from-literal=azurestorageaccountname=$AKS_STORAGE_ACCOUNT_NAME --from-literal=azurestorageaccountkey=$AKS_STORAGE_KEY

Setting up ingress in a mixed cluster
