Running Akka Cluster in Azure Container Service (ACS)

Recommended Reading

Recommendations

  • Do a deployment to Minikube first to learn how the install script works
  • Upgrade to Pay-As-You-Go subscription, as the Free Trial will place very limited quotas that will make it difficult to impossible to spin up k8s clusters
  • Azure CLI seems to be very raw in regards to the Container Service. If you have problems, look at the Github issues
  • Don't rely on the Azure Web Console for much of anything; stick to the CLI

Install the Azure CLI

brew install azure-cli

Login via the Azure CLI

After creating your Azure account, you will be able to log in through the CLI and the web browser.

az login
To sign in, use a web browser to open the page https://aka.ms/devicelogin and enter the code

Create Resource Group

az group create --name customer --location eastus

{
  "id": "/subscriptions/e8b1d29a-7336-49c8-9add-f9336020a5d1/resourceGroups/customer",
  "location": "eastus",
  "managedBy": null,
  "name": "customer",
  "properties": {
    "provisioningState": "Succeeded"
  },
  "tags": null
}

Create Kubernetes Cluster

az acs create --orchestrator-type kubernetes --resource-group customer --name akka-customer --agent-vm-size Standard_DS1_v2 --agent-count 2
