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

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...)

1. Installing Docker

#apt-get install docker*

2. Checking the version

#docker version

Machine: Your Laptop
Cloud: Google Cloud Engine

Open The PowerSHell and start running these commands:

$ gcloud auth login
$ docker-machine create --driver google --google-project collabnixx-1346 test-master1

$docker-machine ssh test-master1
But it throws garbage value when you try to do backspace...

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

Platform: Google Cloud
Docker Version: 1.12.1

Setting up Master-1:

master ==>sudo docker swarm init --listen-addr  10.140.0.3
Swarm initialized: current node (doc7u22kg42bo9x0zrjbwtk86) is now a manager.
To add a worker to this swarm, run the following command:
    docker swarm join \
    --token SWMTKN-1-02u85v6ggoj4em6e5v6rbjemgo9q324i9sced6dqkr54dyh3k8-68mxomvfy0htjbqm51dz60rtl \

Steps:(I tested it as root user just for quick setup)

#cat script-test 

export PATH=/usr/local/go/bin:$PATH
mkdir -p ~/go
export GOPATH=!$
export PATH=$GOPATH/bin:$PATH
mkdir -p ~/go/src/github.com/docker
cd !$
