subsequent commands will begin to exist as the first layer of the image. Without any system, you can directly copy executable files to images such as swarm, coreos/etcd. In Linux, static compilation programs do not need the operating system to provide runtime support. All the required libraries are already in the executable file. Therefore, direct from scratch will make the image smaller.From syntax format

OverviewKubernetes is a powerful container orchestration tool that enables users to reliably deploy and run containerized applications on a scalable system. Within the container area, k8s has undoubtedly become a community standard for container orchestration and management, and even Docker has announced support for K8s. The fighting in the field of container orchestration has been turned around, and the dust settles, and k8s has been unanimously endorsed by the players including Google, Huawei,

This is a creation in Article, where the information may have evolved or changed. "The editor's words" Now, when it comes to "containers," almost all people first think of Docker. As the most mainstream container standard, Docker masks the brilliance of many predecessors and successors. In fact, Docker is neither the first container class product (OpenVZ, LXC, etc.), nor the last. Today we're going to talk about a new container that has a recent ignition standard: AppC. APPC is a community proj

Kubernetes introduced Kubeadm from 1.3 to try to simplify its complex installation. But Kubeadm is still not stable, and I personally think Kubeadm instead of trouble, rather than directly with the script or other automated tools to install the neat. There are also alternatives to HA for KUBEADM configuration master, such as using highly available cluster software such as keepalived or Corosync. So in this document, I will still use the traditional way to install the Kubernetes clusterKubernetes
