perspective, in Google, developers can improve productivity and service availability by using this enhanced collaborative approach, which makes the deployment on large-scale clusters more agile.However, our technology is still in its early stages of development. At present, Kubernetes has been adopted by many well-known teams of customers and companies, including RedHat, VMware, CoreOS and Mesosphere. These companies are eager to use the large-scale

You may get duplicate callbacks
You could not get a callback @ All (lost in limbo)
You may get Out-of-band errors
Emitters may get multiple "error" events
Missing "error" events sends everything to hell
Often unsure what requires "error" handlers

GODEP is currently golang the mainstream package management tool, a lot of go language-based projects such as Docker, CoreOS, kubernetes, etc. are using GODEP to solve project package dependencies and versioning issues. As a command-line tool, GODEP is simple, common basic GODEP Save and GODEP restore two commands are enough, so the general novice with official instructi
Why shouldn't the data center be filled with islands?
With the emergence of a large number of new cloud technologies, many companies have begun to seriously consider which platform technology is used for Standardization. Many of them have considered conducting experiments first, or wait and see before other companies can succeed. Excessive pursuit of the latest technology will lead to the need for users to maintain too many platforms, and these platforms will become isolated islands within the
CoreOS, it seems that these companies that have the right to speak in the cloud computing field cannot embrace Docker. Ubuntu Core is a small server operating system that uses the same existing Ubuntu library and uses a simpler mechanism (container) for users to install applications. In addition, the container mechanism used by Ubuntu Core is also compatible with Docker.
