为了在 OpenShift 中创建新应用程序您可以使用 oc new-app 命令创建应用使用 --strategy 标志来指定要使用的构建策略。–strategy 标志可以采用多个值包括
docker此策略从 Dockerfile 构建应用程序。source此策略使用 Source-to-Image (S2I) 工具从源代码构建应用程序。pipeline此策略使用 Jenkins 管道构建应用程序。
使用了 --strategysource 标志这意味着 OpenShift 将使用 S2I 工具从源代码构建应用程序。S2I 是 OpenShift 中的一个工具它允许开发人员从他们的源代码构建可重现的 Docker 镜像。S2I 通过提供构建和运行容器应用程序的框架简化了构建镜像的过程。
S2I 的工作原理是将您的源代码与基础镜像结合起来创建一个新的镜像该镜像可以在容器中运行。基础镜像为您的应用程序提供运行时环境而源代码则提供应用程序代码。S2I 还允许您通过提供可以在构建过程中运行的脚本来自定义构建过程。
要在 OpenShift 中创建 S2I 构建您可以使用 oc new-app 命令和 --strategysource 标志。这将创建一个新的构建配置该配置使用 S2I 构建您的应用程序。然后您可以将源代码推送到构建配置中OpenShift 将自动为您构建一个新的镜像。
以下是使用 oc new-app 命令在 OpenShift 中创建 S2I 构建的示例 基于 IS 创建应用
$ oc new-app --namemysql -i mysql:latest -e MYSQL_ROOT_PASSWORDredhat 使用 -i, --image-stream 指定 IS 的镜像位置
要在 OpenShift 上创建一个基于 ImageStream (IS) 的应用可以按照以下步骤进行操作
创建一个新项目或选择一个现有项目。运行以下命令创建一个 ImageStream # 这将在当前项目中创建一个指定名称的新 ImageStream。oc create is imagestream-name运行以下命令将镜像导入 ImageStream #这将从指定的 URL 导入镜像到 ImageStream 中。oc import-image imagestream-name --fromimage-url --confirm运行以下命令创建一个新应用 oc new-app -i imagestream-name这将创建一个基于 ImageStream 的新应用程序。
在此过程中将自动生成多个 API 资源对象包括
ImageStreamImageStreamTagDeploymentConfigDeploymentReplicationcontrollerReplicasetServiceRoute(路由对象需要手动创建)
当镜像被导入 ImageStream 时将创建 ImageStream 和 ImageStreamTag 资源。当创建新应用程序时将创建 DeploymentConfig、Service 和 Route 资源。
这里我们看一个 Demo创建一个 ImageStream

基于模板创建应用
$ oc new-app --templateruby-helloworld-sample --paramMYSQL_USERadmin $ oc new-app --file./example/myapp/template.json --paramMYSQL_USERadmi n 以下是使用模板在OpenShift中创建应用的步骤
使用 oc login 命令登录到您的OpenShift集群。使用 oc new-project 命令创建一个新项目。使用 oc get templates -n openshift 命令浏览可用的模板。选择适合您需求的模板使用 oc new-app 命令创建一个应用。您可以使用 -p 标志指定模板名称和任何参数值。使用 oc get pods 命令监视部署。
当您从模板创建应用时OpenShift会创建多个资源对象包括DeploymentConfig、Service、Route和ImageStream。这些对象一起工作以部署和公开您的应用程序。
DeploymentConfig对象定义了应用程序的部署方式包括副本数、要使用的容器映像以及任何环境变量或卷挂载。Service对象为您的应用程序提供稳定的IP地址和DNS名称允许其他服务与其通信。Route对象将您的应用程序公开给外部世界提供用户可以访问的URL。最后ImageStream对象跟踪应用程序使用的容器映像允许您回滚到以前的版本(如果需要)。
