[TOC]DescriptionThere is no detailed explanation of the Kubernetes's service exposure and Traefik's principles. The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant increase in the core API resource types until

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 settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL data in the Mysql-sonar container.

What is PodPods are the smallest deployable units that can be used to create and manage kubernetes calculations. A pod represents a process that runs in a cluster.Pods are like pea pods, which consist of one or more containers (such as Docker containers) that share container storage, network, and container run configuration items. The containers in the pod are always dispatched at the same time and have a common operating environment. You can think of

In the case of manual installation (for the case where the source code is compiled for PG or the decompressed version is installed for PG), PG does not start automatically when it is started, and stops automatically when it is turned off, as a DBA, this is obviously unacceptable. 1. Self-starting services in Windows In Windows, you can use the pg_ctl command to generate the postgresql service and enable it to start itself. In fact, the installation v

Basic knowledgeFirst: Docker is an open-source container, in fact this technology is not new. In the early days of Linux, there was a lightweight virtualization system like LXC. Docker is actually just a language to implement. Kubernetes means the helmsman of sailing, it's a powerful orchestration + Monitor + disaster preparedness + load management system for DockerSecond: Kubernetes is a summary and best p
