Step 1 : Create Docker machines (to act as nodes for Docker Swarm) Create one machine as manager and others as workers

`docker-machine create --driver hyperv manager1`    
`docker-machine create --driver virtualbox manager1`

docker-machine:Error with pre-create check: “exit status 126” https://stackoverflow.com/questions/3... brew cask install virtualbox;

Create one manager machine and other worker machines

Step 2 : Check machine created successfully

`docker-machine ls`
`docker-machine ip manager1`

Step 3 : SSH (connect) to docker machine

`docker-machine ssh manager1`

Step 4 : Initialize Docker Swarm

docker swarm init --advertise-addr MANAGER_IP

docker node ls (this command will work only in swarm manager and not in worker)

Step 5 : Join workers in the swarm Get command for joining as worker In manager node run command docker swarm join-token worker This will give command to join swarm as worker

`docker swarm join-token manager`

This will give command to join swarm as manager

SSH into worker node (machine) and run command to join swarm as worker

In Manager Run command - docker node ls to verify worker is registered and is ready

Do this for all worker machines

Step 6 : On manager run standard docker commands docker info check the swarm section no of manager, nodes etc

Now check docker swarm command options 
docker swarm 

Step 7 : Run containers on Docker Swarm docker service create --replicas 3 -p 80:80 --name serviceName nginx Check the status: docker service ls docker service ps serviceName Check the service running on all nodes Check on the browser by giving ip for all nodes

Step 8 : Scale service up and down On manager node docker service scale serviceName=2

Inspecting Nodes (this command can run only on manager node) docker node inspect nodename

docker node inspect self

docker node inspect worker1

Step 9 : Shutdown node

docker node update --availability drain worker1

Step 10 : Update service

docker service update --image imagename:version web

docker service update --image nginx:1.14.0 serviceName

Step 11 : Remove service

docker service rm serviceName

docker swarm leave : to leave the swarm

docker-machine stop machineName : to stop the machine

docker-machine rm machineName : to remove the machine
