Docker – Environment Variables, Env File & A Little Django (Python)

October 12, 2021October 12, 2021 ~ Geek_Dude

Why Use Environment Variables? Whilst building my Django project I replaced several of the values within settings.py with an option for them to be read from environment variables, rather than storing them in plain text within settings.py. This change allows me to store the settings.py file within a source control repository (e.g. Git) and also … Continue reading Docker – Environment Variables, Env File & A Little Django (Python)

I have … Continue reading Grafana – Using An API Call To Add DataSources (Python)
