Structure diagram

Description:

1. Etcd can be clustered, and any node in the cluster can read and write. You can experiment by yourself. Here, in order to simplify the whole structure, etcd uses a

2. Instead of using the image of the official website, the swarm in this experiment is compiled and installed on the physical machine.

3. Swarm management machine and all docker host hosts need to install swarm. The management node runs the swarm manage command and the docker host host runs the swarm join command

Etcd starts etcd on a stand-alone machine-- name etcd0-- initial-advertise-peer-urls http://192.168.0.201:2380\-- listen-peer-urls http://192.168.0.201:2380\-- listen-client-urls http://192.168.0.201:2379\-- advertise-client-urls http://192.168.0.201 : 2379\-- initial-cluster etcd0= http://192.168.0.201:2380swarm management machine starts

Swarm manage-H 0.0.0.0 2375 host configuration

First, configure docker to TCP listening mode, and the listening port for this experiment is 2375.

Next, add the docker host to the management machine and configure it as follows:

Docker host1

Swarm join-- advertise 192.168.0.202 etcd://192.168.0.201:2379/swarm

Docker host2

Swarm join-- advertise 192.168.0.203 etcd://192.168.0.201:2379/swarm

At this point, the whole structure is up.
