how to install kubernetes

basic process.Build the EnvironmentIn the first step, we need to kuberntes the binary executables of each component. The following two ways are available: Download the source code to compile yourself: git clone https://github.com/GoogleCloudPlatform/kubernetes.git CD Kubernetes/build ./release.sh Directly download the tar file that has been compiled and packaged: wget https://storage.googl

Kubernetes architecture and component introduction of open-source container Cluster Management System This article is based on an Infoq article (see the reference section) and has been modified based on your understanding in difficult areas. For more information about deploying kubernetes on Ubuntu, see. Together we will ensure that Kubernetes is a strong and ope

Kubernetes node nodes contain the following components: Kublete Kube-proxy Docker-ce Flanneld Installation configuration Docker-ceuninstall old versionsyum remove docker docker-common docker-selinux docker-engine -yansible k8s-node -a 'yum remove docker docker-common docker-selinux docker-engine -y'Install Docker CE# install required packagesyum

two more points that need your attention: Ideally choose a dual-core host with at least 2GB of RAM; If you can select a custom user name when you configure the host, you will need to choose a custom username to discard the root selection. For example, Civo provides an option for ubuntu,civo or root; Now perform the following steps on each machine, which may take you 5-10 minutes. If you think this process is too slow, you can also enter the following command to use the utility script I made:

Kubernetes Kubeadm installation requires the following four packages Kubelet Kubernetes-cni Kubeadm kubectl These four packages can be downloaded via the Https://github.com/kubernetes/kubernetes warehouse to perform make fetch installation packages, and the release version is required if the RPM package is required.

Kubernetes, as an important member of the Docker ecosystem, is an open source version of Google's many years of large-scale container management technology, as Urs Hölzle said, whether it is a public cloud or a private cloud or even a hybrid cloud, kubernetes will be used as an application for any The container management framework for any environment is ubiquitous. Because of this, it is now favored by maj

Service discovery mechanism Kubernetes provides two ways to discover the service:1. Environment Variables When the pod is running, Kubernetes writes the information for the service that existed before This method requires that the pod must be started after the service. The pod that was started before the service will not have an environment variable for that service. There is no such limit in the way
