VIA - Very Important App

This repository is a basic scaffold for a containerized app. It makes use of environment variables for configuration and is meant as part of a Kubernetes kickstart.

Knobs & Wheels

The following environment variables are used:

• VERSION - shown as-is
• STAGE - if either dev, int or prod, loads a corresponding stylesheet
• PORT - used by gunicorn, which binds to this port

Furthermore, the whole env is visible in the app.

Dependencies

cd app
python -m venv .venv  # do this in a virtual environment to isolate dependencies
source .venv/bin/activate  # actually use the new environment in this shell
pip install -r requirements.txt  # install dependencies

Usage

You can run this either with flask directly:

cd app
flask --app app run

or using gunicorn as aWSGI server:

cd app
./serve.sh

Building

TAG=chtime/via:latest
podman build -t $TAG .

Deploying on OpenShift

You can directly import this via the OpenShift console into a cluster. More details are in resources.
