Maven / Fabric8-针对远程OpenShift安装构建一个OpenShift容器映像

如何解决Maven / Fabric8-针对远程OpenShift安装构建一个OpenShift容器映像

使用Docker，我只需要提供DOCKER_HOST和适当的凭据即可使fabric8插件能够构建我的容器映像。只要有Docker Registry，就不需要在构建映像的实际主机（例如，我的Bamboo代理）上安装与Docker相关的基础架构。

使用OpenShift时，我似乎找不到找到此方法的方法。相反，似乎我必须在已安装OpenShift的主机上运行Maven目标，该主机必须是RedHat Linux主机。

这似乎要复杂得多。我在这里想念东西吗？

在openshift模式下，是否可以通过fabric8-maven-plugin引用远程OpenShift环境？

谢谢，罗宾。

解决方法

我来自Fabric8团队。您无需从已安装OpenShift的主机运行目标。插件会读取~/.kube/config来获取与OpenShift集群有关的信息，并使用您的API令牌与OpenShift REST API进行交互。

Fabric8 Maven Plugin已迁移到Eclipse JKube。尽管Fabric8 Maven插件也可以与远程OpenShift群集很好地配合使用。它是相同的Fabric8 Maven插件，但具有不同的名称和目标OpenShift插件。我将使用Eclipse JKube的OpenShift Maven Plugin给出此答案。您可以像这样在您的pom.xml中放置它：

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

这是一个使用简单的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您的OpenShift集群：

~ : $ 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".

1. 转到您的项目并发布OpenShift Maven插件目标：
