ObjectiveThis article is a reading note, specific reference to Mr. Nu Bongfei's original "Kubernetes Guide", thank the original author, salute!I. Introduction of BorgBorg is a large-scale cluster management system within Google, which is responsible for the scheduling and management of many core services within Google.The goal of Borg is to enable users to focus on their core business without having to worry about resource management, and to maximize

Kubernetes cluster, and using the cAdvisor built-in tools to monitor container resource utilization.First, we need to install kubelet and run it. Use this guide in CoreOS Linux 773.1.0 or later.Use systemd to configure Kubelet CoreOS Linux integrates kubelet by default, and implements Security optimization and usability optimization. However, security restrictions will be relaxed to support advanced containers. This requires running the Proxy compone

Status Gets the status of a loc

integrated with Kubelet and is optimized for security and ease of use. But we will be easing security restrictions to support premium containers. This requires running the agent component on a single-node Kubernetes, which requires iptables operation permissions to facilitate configuration of the Kubernetes service discovery model.Create Kubelet systemd (System

lightweight and easy tools, where I will share 3 of my favorite tools that will help us complete our first project.1. Go-skel–go Language micro-service skeleton, just execute run./skel.sh test123, it will create test123 for the new Go Project skeleton.2. Vendor management tools for Trash–go languages. There are actually a lot of dependency management tools, but in terms of temporary dependency management, trash is very good and simple to use.3. dappe

Kubernetes API Server FeaturesThe core function of Kubernete API server is to provide an HTTP rest interface for kubernetes, deleting, changing, checking, and watch for various resource objects (such as Node,pod,service, etc.).The API server is the central hub for data interaction and communication between the various functional modules in the cluster, in additio

Kubernetes is a docker-based, open-source container cluster management system initiated and maintained by the Google team that not only supports common cloud platforms, but also supports internal data centers.Built on top of Docker, Kubernetes can build a container scheduling service that allows users to manage cloud container clusters through

architecture and core functions are always relatively stable. Compared to Mesos, the cost of development based on Kubernetes is lower, especially after familiarity. Easy to promote the use of k8s. In addition to the main business platform Bay, our load balancing platform, Kafka platform and scheduled task platform are all basic Kubernetes.
