We will use the Azure portal (portal.azure.com) to create our environment for ACS. When creating our containers-based application environment, we will have the option to choose the required container orchestrator, and we choose Docker Swarm. We select one master node and two agent nodes for our container cluster managed by Docker Swarm. This means we will have two VMs for agent nodes and one VM for the master node in the docker swarm setup. When using the Azure portal for creating our ACS, it will drive us through the Azure Resource Manager (ARM) template for the ACS cluster, and choosing Swarm for orchestrator will follow this way of setting up our environment.
We will see more detailed and fundamental screens for the ACS and Docker image setup in later sections. For step-by-step guidance, please follow the link as mentioned in the later part of the section Hands-on prerequisites.
