kubernetes service discovery

optimization goal is CPU utilization average 30%), resulting in high technology costs. The ideal situation, if the operation of the machine, all through a portal, unified management, unified grasp of the use of cluster resources, the cluster needs to expand or shrink capacity, as long as the increase or recovery of the server, the need for a service expansion capacity, as long as a simple set of replicas quantity. That would be nice. (Of course

This article will be based on the previous article on the configuration of the DNS service in the Kubernetes cluster environment, in the k8s cluster, pod life cycle is short, pod restart IP address will change, for the application this is unacceptable, in order to solve this problem, The k8s cluster cleverly introduces the DNS service to realize the

Kubernetes Cluster Deployment DNS ServiceIn Kubernetes each service will be assigned a virtual IP, each service under normal circumstances will not change for a long time, this is relative to the pod of the indefinite IP, the use of the cluster app is relatively stable.But the service's information injected into the po

First, how to solve the hard coding problem Last lesson we learned about the service provider and service providers, one of the very big problem is hard coding problem, it is well known that in the Internet development, the IP and port number of access address is dynamic, a service is stopped and re-enabled after the IP and port may have changed, so hard coding i

collection must know the addresses of all other nodes, but when a container is rearranged, its IP address changes. For example, all containers within a kubernetes share an IP address that changes after the pod is rearranged. In kubernetes, this problem can be resolved by contacting the Kubernetes service with the Mong

Recently, Bocloud Boyun novel formally received the CNCF and Linux Fund certified Kubernetes Service Provider qualification (KCSP), which proves Bocloud Boyun novel activities in the Kubernetes community (including active contribution code), business model supporting enterprise end users , as well as the presence of engineers on the site of the three sides have t

On the road to Spring-cloud MicroServices (ii): Spring boot We showed you how to quickly build a microservices project using spring boot, which demonstrates how to use spring cloud Eureka and Spring Cloud C respectively Onsul complete the implementation of service registration and discovery.
