Azure container service does not install SWARM?

I am attempting to use Azure container service , I can deploy and connect to it however it appears that Swarm in not active

swarm-master-E4011A18-0:~$ docker node ls
Error response from daemon: This node is not a swarm manager. Use “docker swarm init” or “docker swarm join” to connect this node to swarm and try again.
s@swarm-master-E4011A18-0:~$

I recommend using Docker for Azure: https://docs.docker.com/docker-for-azure/

When using the Azure Container Service, and selecting Swarm as the orchestrator, Swarm will be distributed as a separate container like it happend before the built-in Swarm in Docker v1.12 was made available.

So by using the container services you are not using the Docker v1.12+ built-in version of Swarm.

As Michael states, the Docker for Azure template that docker offers delivers you the full modern Docker swarm stack that integrates well with Azure, but that does not use the Azure Container Service.
