I simulated a small Tor network using Docker.One DA,One Client,Three relays——relay1、relay2、relay3。when I run tor on relay nodes,I found that the relay node is attempting to create and extend circuits like the picture。 enter image description here

Three relay nodes' torrc files are as pictures: enter image description here

Why does this phenomenon occur? What I want is for only the client to create circuits, with the relay node only acting as a packet forwarder. How should I configure it?

it's a control connection from your nyx - the red line. Additionally - keep in mind that Tor nodes are not just "standing still", they are participating in the consensus - including node speed measurements e.t.c.
