Swarm Introduction Since its inception, the container features and mirroring features of Docker have brought a lot of convenience to devops enthusiasts. For a long time, however, Docker can only run on a single host, and its ability to deploy, run, and manage across hosts has been widely criticized. The weak cross-host capability leads directly to the tight coup

Docker Swarm is a tool for creating server clusters. Tie a bunch of servers together and make them look like a server that runs applications on these servers through a unified interface. Servers in a cluster know each other, and they know which servers are running what services, and if the access service does not exist on the server, it transfers access to the correct server in the cluster. A service can b

ObjectiveIn Docker engine v1.12, using swarm can easily create a overlay mode network, but it can only be used by the service below Swarm, which is completely isolated relative to container. In v1.13, when running containers, you can join the overlay network that was previously customized in swarm mode!1. Create
