I explain about how to deploy OpenFaaS on Kubernetes on Azure. However, OpenFaaS supports Swarm as well. What is the most easy way to deploy it? Since the OpenFaaS requires docker ce for 17.05+, we can't use Azure Container Service. Instead, we can use Docker for Azure. It is the most easiest way to deploy 17.06+ swarm mode cluster on Azure, currently.
Let's deploy it.
Deploy Docker for Azure
Go to this site. You can deploy the cluster directly. Just click "Deploy Docker Community Edition for Azure (Stable)"
Then you can see this page. You can edit the template if you like.
Connect to the Docker for Azure
After the deployment, you can find the externalSSHLoadBalancer which have an IP address to access the master nodes.
If you have three master nodes, then the SSH port will be 50000, 50001, and 50002. You can check it out on the externalSSHLoadBalancer > Inbound NAT Rules
You can tunnel it to deploy OpenFaaS. If the loadbalancer's IP is 126.96.36.199, then the command is like this. NOTE: the default user name is docker. not azureuser!
ssh -p 50000 -fNL localhost:2374:/var/run/docker.sock firstname.lastname@example.org export DOCKER_HOST=:2374
Just clone the OpenFaaS and deploy it.
git clone email@example.com:alexellis/faas.git cd faas ./deploy-stack.sh
Finish. Then you can check it out. If the all nodes status is OK and replicas are not 0, then it works.

Open the OpenFaaS potal
As you can see, All you need to do is find the externalLoadBalancer on the Resource Group, then access the URL with port 8080. You can refer OpenFaaS on ACS (Kubernetes) for seeing the faas-cli setting.
