4.6. 部署 Python 应用程序

流程

1. 要创建新 Python 应用程序，请输入以下命令：

   $ oc new-app python~https://github.com/openshift-roadshow/nationalparks-py.git --name nationalparks -l 'app=national-parks-app,component=nationalparks,role=backend,app.kubernetes.io/part-of=national-parks-app,app.kubernetes.io/name=python' --allow-missing-images=true

   --> Found image 0406f6c (13 days old) in image stream "openshift/python" under tag "3.9-ubi8" for "python"
   
       Python 3.9
       ----------
       Python 3.9 available as container is a base platform for building and running various Python 3.9 applications and frameworks. Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python's elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
   
       Tags: builder, python, python39, python-39, rh-python39
   
       * A source build using source code from https://github.com/openshift-roadshow/nationalparks-py.git will be created
         * The resulting image will be pushed to image stream tag "nationalparks:latest"
         * Use 'oc start-build' to trigger a new build
   
   --> Creating resources with label app=national-parks-app,app.kubernetes.io/name=python,app.kubernetes.io/part-of=national-parks-app,component=nationalparks,role=backend ...
       imagestream.image.openshift.io "nationalparks" created
       buildconfig.build.openshift.io "nationalparks" created
       deployment.apps "nationalparks" created
       service "nationalparks" created
   --> Success

2. 要创建公开应用程序 nationalparks 的路由，请使用以下命令：

   $ oc create route edge nationalparks --service=nationalparks

   Copy to Clipboard Toggle word wrap

   输出示例

   route.route.openshift.io/parksmap created

   Copy to Clipboard Toggle word wrap

3. 要检索创建的应用程序路由，请输入以下命令：

   $ oc get route
