3.4.3. 从镜像创建应用程序
您可以使用 oc new-app 命令从 Docker Hub 中的容器镜像、私有 registry 或集群中的镜像流创建应用程序。当您知道要部署的容器镜像名称或镜像流时，请使用这个步骤。
使用与存储容器镜像的位置匹配的 命令。
注意
如果指定本地 Docker 存储库中的镜像，必须确保同一镜像可供 OpenShift Container Platform 节点使用。
先决条件
-
已安装 OpenShift CLI (
oc)并登录到集群。 - 您知道要部署的容器镜像名称或镜像流。
流程
运行以下命令，从 Docker Hub MySQL 镜像创建应用程序：
$ oc new-app mysql通过在以下命令中指定完整镜像路径，从私有 registry 中的镜像创建应用程序：
$ oc new-app myregistry:5000/example/myimage运行以下命令，从现有镜像流和可选镜像流标签创建应用程序：
$ oc new-app my-stream:v1
