Meet your needsUsing Nginx to do load balancing, the manual way is to add or remove the backend server in the upstream, more trouble.Through Registrator collection needs to register to consul as Nginx backend server information and then register to consul Key/value. Consul-template go to Consul key/value to read the in

Implementation requirements:Using Haproxy To do load balancing, manually add or remove node server information in the configuration file, it is more troublesome. Collect the information that needs to be registered to Consul as the Haproxy node server through Registrator, and then register to Consul Key/value . Consul-template go to

Service discovery is one of the key principles of micro-service architecture. Trying to configure each client or some form of convention can be very difficult and very fragile. Consul provides service discovery services through HTTP APIs and DNS. Spring Cloud Consul uses the HTTP API for service registration and discovery. This does not prevent non-spring cloud applications from taking advantage of the DNS

. Applications should give full play to the potential of kubernetes.The kubernetes application is communicating using the service. There are different types of services in Kubernetes, and they are treated as load balancers. The service name defined is your endpoint http://service_name:port.If you are using a stateful application, you will want to use headless services to access specific pods.

Automatic failover of MHA Based on consul architecture, consulmhaIntroduction For a long time, we have not enabled the masterha_manager automatic switch script online, because the database cannot be accessed due to network jitter (network cable, Cabinet switch instability. for example, restarting the NIC of the machine where the detection script is located does not indicate a problem with the database. Therefore, we cannot judge that the database is i

This is a creation in Article, where the information may have evolved or changed. "Editor's note" This article compares three service discovery tools for zookeeper, ETCD, and Consul, and explores the best solution for service discovery, for informational purposes only. If you use a predefined port, the more services you have, the greater the likelihood of a conflict, after all, it is impossible to have two services listening on the same port. Managin
