Quick Start Guide

  1. Edit the hosts in the hosts.ini file as well as the authentication type. Swarm manager nodes should be placed under 'docker_swarm_manager' and swarm worker nodes should be placed under 'docker_swarm_mworker'.
  2. Edit the 'swarm_iface' default variable in the docker role to match the primary iface used to communicate with nodes.
  3. Check all hosts are accessible: ansible all -m ping -i production/hosts.ini
  4. Run the playbook: ansible-playbook -i production/hosts.ini site.yml

AWS Notes

  1. Open protocols and ports between the hosts The following ports must be available. On some systems, these ports are open by default.
  • TCP port 2377 for cluster management communications
  • TCP and UDP port 7946 for communication among nodes
  • UDP port 4789 for overlay network traffic
