将环境变量添加到OpenShift中已部署的应用程序中
[英]Adding environment variables to already deployed application in OpenShift
问题描述
I currently have a process in place to build and deploy our application to OpenShift utilizing the Jenkins OpenShift plugin via the commands below: 
我目前有一个使用Jenkins OpenShift插件通过以下命令将应用程序构建和部署到OpenShift的过程：
openshift.newBuild("--image-stream=${builderImageName}", "--binary=true", "-n ${projectName}", "--to=${applicationName}:${targetEnv}")
openshift.startBuild("${applicationName}", "--from-dir=.", "--wait=true", "-n ${projectName}")
openshift.newApp("-n ${projectName}", "--template=${templateName}", "--param-file=${appDeployConfigFileName}", "--env-file=${appEnvFileName}")
This works as intended. 这按预期工作。 My question is once the app has been deployed how can I update the env variables if additional ones need to be added? 我的问题是，一旦部署了应用程序，如果需要添加其他变量，如何更新环境变量？ I basically want to duplicate the functionality of going through the ui and adding env variables. 我基本上想复制通过ui和添加env变量的功能。 However I would want to do this using the openshift plugin or oc tool and use a file of variables not just a set of key values. 但是，我想使用openshift插件或oc工具来执行此操作，并使用变量文件而不只是一组键值。

您将需要为您的应用程序更新部署配置
oc set env dc/<your_app> MYVAR=foo -n <project_name>

If you're trying to store environment variables in SCM with a builder image (w/ S2I aka source-to-image enabled container image), use an environment file .s2i/environment . 如果您尝试将环境变量与构建器映像（带有S2I或启用了源到映像的容器映像）存储在SCM中，请使用环境文件.s2i/environment 。
