Last time, the swarm cluster environment has been set up. There are three virtual machines, server01, server02 and server03. Each manager node is also a work node. First, we consider the discovery of services. From the perspective of microservices, we have services for other services, such as message service and user service. For swarm, some ports need to be exposed to For other services, some can be accessed directly through the name of the service. Change the mode, change the code, and then upload it to the image warehouse. Finally, configure a docker stack to write their relationship, and a command is completed.

docker stack is created. Because the machine memory is too small, I still use the Internet. Downloading the image is a little slow.
docker stack deploy -c ms-service.yml ms docker stack services ms
PS: the next step is to debug the microservice.
