如何在 Openshift 上部署 war 和应用程序

Question

我正在按照 this 教程在 Openshift 应用程序上安装 Geoserver。问题是对于 Geoserver (a .war) 到运行，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，如何在拥有 WAR 运行ning 的同时维护 pom.xml 和 src 文件夹（我真的需要删除这些东西才能获得 war运行宁）？有可能吗？

使用 src 文件夹和 pom.xml 我收到了来自 Openshift 的回复：

Posdata：我知道如何在其自己的上下文中将 war 变为运行（例如 http://test-testdomain.rhcloud.com/war/）。

更新：这是我的rhc tail -a geoserver

此外，我检查了 ${OPENSHIFT_JBOSSEWS_DIR}webapps，我有 geoserver.war 和 ROOT.war.

更新 2: 在 touch 命令之后，我再次 rhc til -a geoserver 并得到：

Answer 1

Openshift 应用程序包含一个 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，如果您 ssh 进入您的应用程序，存储库是位于 $OPENSHIFT_REPO_DIR.

每次您推送到应用程序的存储库时，一系列脚本，在 Openshift 术语中名为 action hooks，是运行。随附的动作挂钩因您选择的墨盒而异。

推入 java 应用程序服务器盒后发生的一件事是触发了 maven 构建，$OPENSHIFT_REPO_DIR 中的内容（src 文件夹和 pom.xml) 用于创建 WAR 工件，该工件也会自动部署到所选模块中包含的应用程序服务器上。

这基本上意味着您只需将源代码推送到存储库，Openshift 会处理所有事情。您根本不需要担心删除任何内容。事实上，如果删除存储库目录的内容，则没有任何内容可用于构建工件。

如果您选择了自己动手 (DIY) 盒式磁带，则您负责管理所有内容，不包括任何脚本或操作挂钩。

更新：可以将两者放在同一档位，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 <profile> 部分，至少 openshift 配置文件保持原样，因为在推送事件中，它将触发一个带有 openshift 配置文件的 maven 构建，这将生成一个 WAR 您的应用程序的工件，并在 webapps 目录中生成一个名为 ROOT.war 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，它为您提供文件 ROOT.war 作为地理服务器应用程序：

您需要将其重命名为其他名称，因为触发的 maven 构建将生成您的应用程序的 ROOT.war 文件，除非您修改 maven-war-plugin 的配置。
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 动作挂钩 。在这种情况下，deploy 阶段似乎是合适的阶段。

你需要在.openshift/action_hooks目录下创建一个文件，命名为deploy，并赋予它执行权限（chmod +x），并将其包含在版本控制中，这样就可以得到与您的应用程序一起启动。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，并且位于 webapps 目录中，这脚本将执行：

#!/bin/bash

echo "Deploying Geoserver application..." 
cp ${OPENSHIFT_REPO_DIR}webapps/geoserver.war ${OPENSHIFT_JBOSSEWS_DIR}/webapps/

Update ：我尝试按照指南重现问题并应用我提到的 tweeks，使用 spring 启动应用程序作为应用程序使用根上下文和地理服务器，但我根本没有发现任何问题。

我遵循的步骤是：

从指南中指定的存储库创建 Openshift 应用程序（tomcat7 + postgresql9.2 cartridges）
克隆存储库
将 webapps/ROOT.war 重命名为 webapps/geoserver.war
创建一个 pom.xml 文件（参见下面的源代码）
在 src 文件夹中包含我的应用程序的源代码（只是一个 Spring 带有 RestController 的启动应用程序，用于 / 入口点说你好世界。
如上所述添加 deploy 动作挂钩
推送代码
