Docker Swarm Port Requirements, both Swarm Mode 1.12+ and Swarm Classic, plus AWS Security Group Style Tables

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

TCP port 2377 for cluster management & raft sync communications
TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
UDP port 4789 for "data plane" VXLAN overlay network traffic
IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option

AWS Security Group Example
