What is Docker’s ingress network in Swarm mode and how does it implement routing mesh?

Accepted Answer

The ingress network in Docker Swarm mode is a special overlay network that enables the routing mesh, allowing any node to accept connections on published service ports and route them to running tasks on any node. This is achieved using IPVS for efficient load balancing.
