The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansi

Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s.

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent
in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flann
[TOC]Brief introductionIn many scenarios, the following initialization is required before the application starts:
Wait for other associated components to run correctly (for example, a database or a background service)
Generate a configuration file based on an environment variable or a configuration template
Get the local desired configuration from the remote database, or register itself in a central database
Download the dependent
The essence of swarm and k8s are container orchestration services.They can abstract the underlying host, and then start the application from a built-in image and eventually deploy it to a host on a docker basis. Which scenario should be chosen as our container cloud service? I think k8s (kubernetes short) and swarm com

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
The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end.
