This article demonstrates the use of the kubernetes system to create a PHP and Redis-based message board system based on Kubeguide-related image files, because system resources are limited, and the Kubernetes cluster has only one master node and slave node.Docker local warehouse and kubernetes cluster configuration Please review the previous article.I. Introducti

Kubernetes is a distributed cluster of Google's Docker based, with the following main components　　ETCD: High-availability storage sharing configuration and service discovery, used as a companion to flannel on Minion machines, to enable Docker running on each minion to have different IP segments The ultimate goal is to make the Docker Containner running on different minion have an IP address that is not the same as any other Containner (Docker Containn

This is the culture and education everyone step by step compile kubernetes. Ready to Before compiling the kubernetes, you should install the build environment first, you need to install the go, install the tutorial please own Baidu. compiling Create a folder Create a Go project folder mkdir kube cd kube mkdir src cd src mkdir k8s.io cd K8s.io Download Source PackageUnder the K8s.io

Containerized technology (containerization).You may have a lot of doubts: what exactly is a container and how does it work? What does Docker and kubernetes mean, and what is the use of Google Container engine and managed VMS? How are they related, and how can we build a powerful service through containers and make them available in a large-scale cluster of production environments? How can you get business value by using this technology? Well, we don't

Services deployed by users on Kubernetes typically run on private networks, and pod and service provide parameters such as Hostport,nodeport to expose these service ports to K8S nodes for user access. There are obvious drawbacks to this approach:1) Easy to occupy excessive host port;2) service ports exposed to multiple hosts increasing the difficulty of firewalls and security configuration3) The default hostport,nodeport mode does not function as load

Brief introductionKubernetes is an open source, containerized application for managing multiple hosts on a cloud platform, with the goal of making deploying containerized applications simple and efficient, Kuernetes provides a mechanism for application deployment, planning, updating, and maintenance.In Kubernetes, all containers are run in pods, and one pod can host one or more related containers. Each pod system created by the user automatically choo
