Useful notes on Docker swarm config

docker-swarm-notes.txt

Docker Hub hosted backend (for test/qa)
=======================================

o create dicovery token

# sid=$(docker run swarm create)
# echo $sid
d3e9cb54c894a7e3ae4c21145b9194bb

o create swarm master node
  
# docker-machine create -d nutanix --nutanix-username admin --nutanix-password 'nutanix/4u' --nutanix-endpoint '10.68.64.55:9440' --nutanix-vm-image Docker-Machine-Image --nutanix-vm-network 'vlan.68' --swarm --swarm-master --swarm-discovery token://$sid swarm-master

o create additional swarm nodes as required 

# docker-machine create -d nutanix --nutanix-username admin --nutanix-password 'nutanix/4u' --nutanix-endpoint '10.68.64.55:9440' --nutanix-vm-image Docker-Machine-Image --nutanix-vm-network 'vlan.68' --swarm --swarm-discovery token://$sid swarm01

o check swarm config 

# docker run swarm list token://d3e9cb54c894a7e3ae4c21145b9194bb
10.68.68.157:2376
10.68.68.156:2376
10.68.68.155:2376
10.68.68.147:2376


eval $(docker-machine env --swarm swarm-master)

docker info
(should show all nodes healthy for ctr placement)

Distributed keystore backend (consul)  
=====================================

o create keystore machine :

docker-machine create -d nutanix --nutanix-username admin --nutanix-password 'nutanix/4u' --nutanix-endpoint '10.68.64.55:9440' --nutanix-vm-image Docker-Machine-Image --nutanix-vm-network 'vlan.68' consul

o run consul backend as a ctr 

docker $(docker-machine config consul) run --restart=unless-stopped -d -p "8500:8500" --name consul  progrium/consul -server -bootstrap

o create swarm manager 

docker-machine create -d nutanix --nutanix-username admin --nutanix-password 'nutanix/4u' --nutanix-endpoint '10.68.64.55:9440' --nutanix-vm-image Docker-Machine-Image --nutanix-vm-network 'vlan.68' --swarm --swarm-master --swarm-discovery="consul://$(docker-machine ip consul):8500" --engine-opt="cluster-store=consul://$(docker-machine ip consul):8500" --engine-opt="cluster-advertise=eth0:2376" manager

o create additional swarm nodes as required 

docker-machine create -d nutanix --nutanix-username admin --nutanix-password 'nutanix/4u' --nutanix-endpoint '10.68.64.55:9440' --nutanix-vm-image Docker-Machine-Image --nutanix-vm-network 'vlan.68' --swarm --swarm-discovery="consul://$(docker-machine ip consul):8500" --engine-opt="cluster-store=consul://$(docker-machine ip consul):8500" --engine-opt="cluster-advertise=eth0:2376" node01


o check swarm config :

eval $(docker-machine env --swarm manager)
docker run swarm list consul://$(docker-machine ip consul):8500/swarm

docker info 
>>> should show all nodes healthy 

e `docker-machine upgrade` command won’t install it. If you create a new machine and use the ` --engine-install-url "https://test.docker.com/"` flag, it will.

Thats until 1.12 goes final, then the upgrade command will work.
