3.7.4. kubecm¶

github [1]

简介:

管理你的 kubeconfig

备注

该项目脱胎于 mergeKubeConfig 项目，最早写该项目的目的是在一堆杂乱无章的 kubeconfig 中自由的切换。随着需要操作的 Kubernetes 集群越来越多，在不同的集群之间切换也越来越麻烦，而操作 Kubernetes 集群的本质不过是通过 kubeconfig 访问 Kubernetes 集群的 API Server，以操作 Kubernetes 的各种资源，而 kubeconfig 不过是一个 yaml 文件，用来保存访问集群的密钥，最早的 mergeKubeConfig 不过是一个操作 yaml 文件的 Python 脚本。而随着 golang 学习的深入，也就动了重写这个项目的念头，就这样 kubecm 诞生了。
