Service is the core concept of k8s. By creating a service, you can provide a unified portal address for a set of container apps that have the same functionality, and distribute the request load to the various containers on the backend to applyService Definition DetailedThe full contents of the service definition file in the Ymal format are as followsapiversion:v1 #必须kind:service #必须matadata: #必须, Meta Data Name:string #必须, the name of the service namespace:string #非必须, specifying the namespace

ObjectiveIngress is a way to expose the internal service of a k8s cluster, and user-edited profiles define a ingress resource to enable external network access to the intranet service.Ingress Controller is to manage all Ingress objects, ingress controller inside is actually an nginx container, when Ingress controll by interacting with the Kubernetes API, When the ingress rule changes in the perceptual cluster, the nginx.conf file is generated accordin

Kubernetes (k8s) DNS Service Restarts the resolution repeatedly: k8s.io/dns/pkg/dns/dns.go:150:failed to List *v1. Service:get https://10.96.0.1:443/api/v1/services?resourceVersion=0:dial TCP 10.96.0.1:443:getsockopt:no route to Host When deploying the Kubernetes service using Minikube, the Kube DNS service is repeatedly restarted (as in error). This is likely

Kubernetes Service Discovery has two ways of environment variables and DNS The way of environment variables In the way of environment variable, SVC must be started before RC, otherwise the cluster IP-related environment variables of this SVC will not be available in other pod. How DNS is DNS must be started, then the resolve.conf file in the container in the pod that is started will take Kube-dns as nam

[TOC]k8s Mount Ceph RBDk8s Mount Ceph RBD There are two ways, one is the traditional way of PVPVC, which means that the administrator needs to pre-create the relevant PV and PVC, and then the corresponding deployment or replication to mount the PVC use. After k8s 1.4, Kubernetes provides a more convenient way to dynamically create PV, that is, Storageclass. Using Storageclass, you do not have to create a fixed-size PV to wait for the consumer to creat

From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed. Scheduling speed encountered bottlenecks, affecting the deployment of large business speed. There is no good support for stateful services. There are two solutions to this problem, one for improved refactoring of ex

Use Kubernetes step by stepWhy Docker and Kubernetes? Containers allow us to build, publish, and run distributed applications. They free applications from machine restrictions and allow us to create a complex application in a certain way. Writing applications using containers can bring development and QA closer to the production environment (if you try to do so ). By doing so, you can publish changes faster

These hosts are deployed with the k8s cluster to the K8S network.For k8s that are not deployed on cloud platforms such as GCE and AWS, w

As we all know, Amazon has EC2 container service, which is the solution that Amazon uses to run Docker containers. But I don't think EC2 container service is very good, so now I'm going to test rancher and Kubernetes on AWS.Kubernetes is an open-source system for automating deployment, scaling, and managing containerized applications. Rancher is a complete container management and runtime platform that can be used within the enterprise, providing ente
