= Deploying a Python application
|
|
|
|
The following procedure deploys a back-end service for the `parksmap` application. The Python application performs 2D geo-spatial queries against a MongoDB database to locate and return map coordinates of all national parks in the world.
|
|
|
|
The deployed back-end service is `nationalparks`.
|
|
|
|
.Prerequisites
|
|
|
|
* You must have access to an {product-title} cluster.
|
|
* You must have installed the OpenShift CLI (`oc`).
|
|
* You have a deployed image.

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.

|
* 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
