五分钟带你玩转apollo使用k8s部署，吐血亲验

Posted 2021-06-19 小黄鸡1992

书接上文 楼主定制了postgresql版本的apollo 那么怎么使用k8s部署呢

ps :本文只部署dev环境 使用yaml文件在Kubernetes-dashboard部署

如果有对Kubernetes-dashboard不熟悉的 可以参考k8s专栏 地址;https://blog.csdn.net/qq_20143059/category_11047349.html

注意：以上yaml 一定注意格式 比如空行 空格 注释 能去掉一定去掉 否则会报各种错误

修改jar包配置

注意 以下apollo-portal.zip中的配置也需要修改（否则一直会访问localhost）
