arska/flask-helloworld repository overview

⁠Python Flask Hello World

This is a very lightweight demo web application serving "Hello World" on TCP port 8080

I use it to demo application deployment to OpenShift on https://appuio.ch⁠

• Web-GUI: "Add to project" -> search for "Python" -> Choose "Python" -> Next -> Version: 3.5, Name: flask-helloworld, Git Repository: https://github.com/arska/flask-helloworld.git⁠ -> Create -> Close

• CLI using source-to-image (s2i)

oc new-app python:3.6~https://github.com/arska/flask-helloworld.git; oc expose service flask-helloworld

• CLI using Dockerfile

oc new-app --strategy=docker https://github.com/arska/flask-helloworld.git; oc expose service flask-helloworld

You can clean up after with:

oc delete all -l app=flask-helloworld

You can also build and run this locally using docker

docker build -t flask-helloworld .
docker run -p 8080:8080 flask-helloworld

the application is then accessible at http://127.0.0.1:8080/⁠
