(docker-discover), Some back-end services (WHOAMI) and the last consumer (Ubuntu/curl).
The registration and Discovery component works as a device and application container, so the registration or discovery code on the backend or consumer container is not embedded. They only listen to ports or connect to other local ports.

But one morning I found that all my computers could not access the internet. Ping ISA fails. It is normal after restart. I check that there are 3 logs in the system log.

I'm lazy. Directly on the diagram of the configuration fileWhere servicename is the service name,LoadBalancer is a load balancing strategy. For the flow control I write a 1s limit of 5 requests to do the test.The rest of the names will be OK.A prerequisite to using service discovery is consul. I this is for the test de
A microservices architecture system, the different services will be called each other, such as an order service needs to fetch user data, you need to invoke user services, there are multiple User Service instances, Eureka load balanced to one of the service instances, and the previous chapter, We first use the Java version of the
Eureka is one of Springcloud Netflix's sub-modules for cloud-service discovery, service positioning, and cloud-tier service discovery and failover. Service registration and discovery is
When using the service discovery, two kinds of annotations are mentioned, one is @enablediscoveryclient, one is @enableeurekaclient, the usage is basically the same, and today it is the same. The following is an explanation of the two found above from StackOverflow:" Discovery Service " in Spring-cloud-commons and pick
