Using Kubernetes for Local Development — Minikube
|
||||
使用 Kubernetes 进行本地开发 - Minikube
|
||||
============================================================
|
||||
|
||||
If you ops team are using Docker and Kubernetes, it is recommended to adopt the same or similar technologies in development. This will reduce the number of incompatibility and portability problems and makes everyone consider the application container a common responsibility of both Dev and Ops teams.
|
||||
|
||||
如果你的运维团队在使用 Docker 和 Kubernetes，那么建议开发上采用相同或相似的技术。这将减少不兼容性和可移植性问题的数量，并使每个人都认为应用程序容器是开发和运维团队的共同责任。

This blog post introduces the usage of Kubernetes in development mode and it is inspired from a screencast that you can find in [Painless Docker Course][10].

Minikube is a tool that makes developers’ life easy by allowing them to use and run a Kubernetes cluster in a local machine.

Minikube 允许开发人员在本地使用和运行 Kubernetes 集群，从而使开发人员的生活变得轻松的一种工具。
