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,

In the previous section we deployed ETCD, and this section installs and configures flannel. Build Flannel
Flannel do not have a ready-made executable file available, you must build it yourself, the most reliable way is to build in the Docker container. But for build Docker mirror hosting in Gcr.io, domestic may not be directly accessible, for the convenience of everyone, I put it mirror to the Docker hub, the construction steps are as follows:
Download and rename the image.

Canonical and Ubuntu founder Mark Shuttleworth said in an interview that he was not ready to announce the new SNAP package format for Ubuntu. But just a few months later, many Linux distribution developers and companies announced that they would use SNAP as a generic Linux package format.Why is it? Because SNAP enables a single binary package to run perfectly and securely on any Linux desktop, server, cloud, or IoT device. According to Canonical's Ubuntu client product and version owner Olli Rie
