Summary

Prerequisites page now describes 2379 as the etcd client port and 2380 as the etcd peer port.

📝 Walkthrough

Walkthrough

The Etcd prerequisite documentation now labels port 2379 for client communication and port 2380 for peer communication, while listing Docker Swarm ports directly with the other required ports.

Changes

Etcd Port Documentation

Layer / File(s)	Summary
Correct Etcd and Swarm port listings docs/prerequisites/index.md	Relabels ports 2379 and 2380 for Etcd client and peer communication, and moves Docker Swarm ports 2377, 7946, and 4789 into the main port list.

Poem

A bunny checks the ports in a row,
“2379 is where clients go!”
“2380 lets peers converse,”
Swarm ports join the verse—
Hop, hop, the clear facts flow!
