鍛骨境-號外1 k8s 里定義證書谍倦，本地計算機使用

自己頒發(fā)證書

這里已經(jīng)在上面的文章里提到過，使用了 cfssl 和 openssl 來作為證書生產(chǎn)工具.

參考：
鍛骨境-第4層 k8s生產(chǎn)環(huán)境高可用集群搭建cfssl 生成pem 證書部分

在第9層，我給dashboard 生產(chǎn)了自定義證書，并實現(xiàn)了如下效果：

注意這里的綠色：連接是安全的灯谣，主要是我們加入了信任的根機構(gòu)證書。
在window上蛔琅，pem 無法直接導(dǎo)入胎许，所以我有使用了openssl 把pem轉(zhuǎn)換成了cer 證書。
注: crt 也是直接可以在windows 安裝的。

怎么做的辜窑？

這里權(quán)當(dāng)做學(xué)習(xí)吧钩述！
