Azure Container Service
The Azure Container Service (ACS) is a cloud-based container deployment and management service that supports popular open-source tools and technologies for container and container orchestration. ACS allows you to run containers at scale in production and manages the underlying infrastructure for you by configuring the appropriate VMs and clusters for you. ACS is orchestrator-agnostic and allows you to use the container orchestration solution that best suits your needs. Learn how to use ACS to scale and orchestrate applications using DC/OS, Docker Swarm, or Kubernetes.
- Operation Engineers
- Anyone interested in managing containers at scale
- Viewers should have a basic understanding of containers.
- Some familiarity with the Azure platform will also be helpful but is not required.
- Demonstrate how to use ACS to create virtual machine hosts and clusters for container orchestration
- Understand how to choose an open-source orchestration solution for ACS
- Understand how to run containers in production on Azure using ACS
- Demonstrate the ability to scale and orchestrate containers with DC/OS, Docker Swarm, and Kubernetes
This Course Includes
- 60 minutes of high-definition video
- Live demonstration on key course concepts

Next I'll show you to do the same thing using the Azure Command Line Interface. Now let's see how to create the same cluster using the Azure Command Line. Once again, I've invoked the Cloud Shell because I can run that from my browser and it doesn't require any type of installation.
What we're going to do is set a few variables in the shell. First, we'll set a name for a resource group, we'll set a name for a location, and then we're going to use the Azure Command Line, command group create, this will create our resource group for us. So we'll use the variable there, and the location variable. Let that run.
Now that the creation has succeeded, we'll create a DNS prefix, remember this is what needs to be unique to access externally, so I'm gonna call it Cloud Academy Azure Container Service Kubes, for Kubernetes. Gonna give it a cluster name of my-k8s-cluster, and then I'm gonna run this command, acs create --orchestrator-type=kubernetes, resource group, and we'll use the resource group variable we created. Name will equal the cluster name, DNS prefix, we'll tell it to generate its own SSH keys, and let that spin.
After several minutes, it's returned back and let me know that the provisioning state has succeeded, so we should be able to take a look, up here. Refresh our resource groups, here's the Cloud Academy ACS, and if we go inside that, we should see the same resources that we saw when we created it through the portal UI. Now that we have it created, let's do a couple more steps just to make sure the cluster's running correctly.
The Azure Cloud Shell comes pre-installed with the Kubernetes Command Line Interface, or the Kube Controller. So what we need to do now is map our credentials to that command line interface, so it knows which cluster it's interacting with. So what we'll do is use the Azure Command Line Interface, the Azure Container Service and pass it through the Kubernetes orchestrator, a command called, get-credentials.
This will pull the down the appropriate credentials based on the resource group that we created, and the cluster that we created. So that will go out and fetch those credentials and then we should be able to use the Kubernetes controller to get nodes and confirm that those agents are running. And as you can see, we have one master and three child agents running on this cluster.
