This article mainly explains "what are the common operations of Docker Swarm". Friends who are interested may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what are the common operations of Docker Swarm?"

Docker Swarm is the cluster management tool of Docker. It transforms the Docker host pool into a single virtual Docker host. Docker Swarm provides standard Docker API, and any tool that has communicated with the Docker daemon can be easily extended to multiple hosts using Swarm.

View cluster node docker node ls to create nginx service # docker pull hub.test.com:5000/almi/nginx:0.1# download private repository image docker service create-- name nginx-- replicas 2-- publish 80:80 hub.test.com:5000/almi/nginx:0.1#--network=swarm_test

# replicas 2 create 2 containers, and hub.test.com is a private repository

View one of the container docker kill 96e6bccc2209 of the service docker service lsdocker service ps nginxkill in the swarm cluster

# etc. will automatically start a new container
