Maven/Fabric8-针对远程OpenShift安装构建OpenShift容器映像

Question

有了Docker，我只需要提供Docker_主机和适当的凭据，fabric8插件就可以构建我的容器映像。只要Docker注册表可用，就不需要在生成映像的实际主机上安装Docker相关的基础设施（例如my Bambole agent）。

使用OpenShift，我似乎找不到这样做的方法。相反，我似乎必须在安装了OpenShift的主机上运行maven goals，该主机必须是RedHat Linux主机。

这似乎比实际情况复杂得多。我是不是遗漏了什么？

在OpenShift模式下，是否有方法从fabric8 maven插件引用远程OpenShift环境？

谢谢你，罗宾。

Answer 1

我是Fabric8队的。您不需要从安装了OpenShift的主机上运行目标。插件读取您的~/。kube/config获取与OpenShift集群相关的信息，并使用API令牌与OpenShift REST API交互。

Fabric8 Maven插件已经迁移到EclipseJkube。尽管Fabric8 Maven插件在远程OpenShift集群上也可以正常工作。这是同一个Fabric8 Maven插件，但有不同的名称和目标OpenShift插件。我会用EclipseJkube的OpenShift Maven插件给出这个答案。你可以把它放在你的pom里。xml如下所示：

<dependency>
  <groupId>org.eclipse.jkube</groupId>
  <artifactId>openshift-maven-plugin</artifactId>
  <version>1.0.0</version>
  <type>maven-plugin</type>
</dependency>

下面是一个使用简单随机生成器应用程序的演示：https://github.com/rohanKanojia/eclipse-jkube-demo-project

1. 使用提供的凭据登录到OpenShift群集：

~ : $ oc login https://your-cluster.openshift.com--token=your-token
Logged into "https://your-cluster.openshift.com:443" as "rohanKanojia" using the token provided.

You have one project on this server: "rokumar"

Using project "rokumar".
