docker compose swarm

1. Swarm is a scheduling framework developed by docker. (Found on the Internet) 2.Server Load balancer: Docker is called ingress load balancing ). It works by listening to published service ports on all worker nodes. When the service is called by an external system, the node that receives the traffic will use the internal DNS service provided by

BackgroundPreviously, the service was created on different servers (Docker host) using Docker swam, and the container between them was communicated through overlay network. Yesterday due to the company's network maintenance, one of the servers (we referred to as manager node) due to maintenance, temporarily unable to connect (probably lasted 6 hours). Come back today, we found that the communication between
