Docker Swarm before 1.12rc2:
1. Setting up Consul for Docker Swarm
sudo docker run --restart=unless-stopped -d -p 8500:8500 -h consul1 progrium/consul -server -bootstrap
2. Setting up Swarm Manager to work with Consul
docker run -d -p 4000:4000 swarm manage -H :4000 --replication --advertise 10.142.0.2:4000 consul://10.142.0.2:8500
View Getting Started with Docker
Getting started with Docker:
1. First Container
root@master1:~# docker run busybox echo hello world
hello world
What we did?
. We used one of the smallest, simplest images available: busybox.
• busybox is typically used in embedded systems (phones, routers...)

Hope:
`--opt encrypted` flag ~ an optional which enables an additional layer of encryption in the overlay driver for vxlan traffic between containers on different nodes
`--subnet` flag ~ specifies the subnet for use with the overlay network. When you don't specify a subnet, the swarm manager automatically chooses a subnet and assigns it to the network.
Note - Before you attach a service to the network, the network only extends to manager nodes
ingress - This is the overlay network on which all exposed ports exist. As explained below, ingress ports are numbered from 30000 through 32000 (user configurable range) and follow a node port model in which each service has the same port on every node in the cluster.
docker_gwbridge - This is the default gateway network. It is the only network with connectivity to the outside.
[user-defined overlay] - This is the overlay network that the user has specified that the container should be on. In the example above, it is mynetwork. Note that a container can be on m

Testing Node Labels under Docker 1.12 Swarm Mode
View gist:6831a5e2e7c6e4955f1a4af8b7693293
Platform: Google Cloud
Docker Version: 1.12.1
Setting up Master-1:

Swarm initialized: current node (doc7u22kg42bo9x0zrjbwtk86) is now a manager.
To add a worker to this swarm, run the following command:
