如何在Openshift上部署战争和应用程序

标签： maven openshift

我正在关注this教程，在Openshift应用程序上安装Geoserver。问题是，要运行Geoserver（.war），我必须从应用程序中删除src文件夹和pom.xml，但我也需要在那里开发一个应用程序。

那么，在运行WAR时我如何保存pom.xml和src文件夹（我真的需要删除这些东西才能让战争运行）？它甚至可能吗？

使用src文件夹和pom.xml我从Openshift收到此响应：

Posdata：我知道如何让战争在自己的背景下运行（例如http://test-testdomain.rhcloud.com/war/）。

更新：这是我的rhc tail -a geoserver

另外，我检查了$ {OPENSHIFT_JBOSSEWS_DIR}网络应用，我有geoserver.war和ROOT.war。

更新2 ：在触摸命令后，我再次rhc til -a geoserver得到：

答案 0 :(得分：0)

Openshift应用程序包括一个git存储库，用于将源代码存储为您创建的每个应用程序中的文件夹，在您推送到存储库后，如果ssh进入应用程序，则存储库位于{{1} }。

每次推送到应用程序的存储库时，都会运行一系列以Openshift术语命名为action hooks的脚本。包含的动作挂钩会因您选择的磁带而变化。

推送java应用程序服务器盒后发生的一件事是触发了maven构建，并使用$OPENSHIFT_REPO_DIR（src文件夹和pom.xml）中的内容创建{ {1}}工件，它也会自动部署在所选盒式磁带中包含的应用程序服务器上。

这基本上意味着您只需要将源代码推送到repo，而Openshift将处理所有内容。您根本不需要担心删除任何内容。实际上，如果删除存储库目录的内容，则无需从中构建工件。

如果您选择了自己动手（DIY）墨盒，您负责管理所有内容，不包含任何脚本或操作挂钩。

更新：两者都可以使用相同的设备，但需要进行一些调整。

首先，您的应用程序，重要的一点是在您的pom.xml中，保留$OPENSHIFT_REPO_DIR部分，至少保留WAR个人资料，因为在推送事件中，它会触发具有<profile>配置文件的maven构建，它将生成应用程序的WAR工件，并在openshift目录中生成名为openshift的文件。此文件将从存储库复制到tomcat部署目录。

现在关于地理服务器，在指南的存储库中，它为您提供了文件ROOT.war作为地理服务器应用程序：

  1. 您需要将其重命名为其他内容，因为触发的maven构建将生成应用程序的ROOT.war文件，除非您修改webapps的配置。

  2. 您需要将重命名的war文件复制到tomcat部署目录。为此，您需要使用操作挂钩。在这种情况下，ROOT.war阶段似乎是合适的阶段。

    3. 您需要在名为maven-war-plugin的{​​{1}}目录中创建一个文件并赋予其执行权限（deploy）并将其包含在版本控制中，因此它将被推送到齿轮和你的应用程序。该文件必须包含一个脚本，其中包含将geoserver WAR文件复制到部署目录的说明，假设您将WAR重命名为geoserver.war，并且驻留在webapps目录中，此脚本将执行：

    .openshift/action_hooks

    更新：我已尝试按照指南重新解决问题并应用我提到的tweeks，使用spring boot应用程序作为使用根上下文的应用程序，以及Geoserver但我根本没有发现任何问题。

    我遵循的步骤是：

    1. 从指南中指定的存储库创建Openshift应用程序（tomcat7 + postgresql9.2 cartridge）
    2. 克隆回购
    3. 将deploy重命名为chmod +x
    4. 创建#!/bin/bash echo "Deploying Geoserver application..." cp ${OPENSHIFT_REPO_DIR}webapps/geoserver.war ${OPENSHIFT_JBOSSEWS_DIR}/webapps/ 文件（请参阅下面的来源）
    5. 将我的应用程序的源代码包含在src文件夹中（只是一个带有RestController的Spring Boot应用程序，用于webapps/ROOT.war入口点的hello world。
    6. 按照上述
      7. 添加webapps/geoserver.war操作挂钩
    7. 推送代码。

      8. <强>的pom.xml
