使用kubernetes-client/java類庫(kù)沦辙，實(shí)現(xiàn)java對(duì)k8s api的調(diào)用
新建maven項(xiàng)目，引入依賴
我的k8s版本是1.5的治拿，所以引入7.0.0的版本
<dependencies>
<dependency>
<groupId>io.kubernetes</groupId>
<artifactId>client-java</artifactId>
<version>7.0.0</version>
<scope>compile</scope>
</dependency>
</dependencies>
將k8s的config文件復(fù)制到項(xiàng)目下
通過(guò)ftp把~/.kube/config下載下來(lái)放到項(xiàng)目下面抛猖。
ftp
config
