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
