The Doppler CLI provided by Doppler is an interactive tool in addition to the dashboard, to easily manage secrets in the CLI. It makes secret management easier for the programmer, provides a simple interface in the form of a dashboard to access stored secrets thereby boosting productivity. What is Doppler?ĭoppler is an amazing service with tools to manage and secure your digital credentials. These credentials could be API keys, SSH keys or even encryption keys used to authorize users to provide access to applications or services. Secret management refers to the methods and tools used to organize, manage and secure digital authentication credentials. We will cover how to set up a Doppler project and migrate our Firebase app credentials from the. The app makes use of its credentials to access and use Firebase services. In this article, we will be using a music application linked to Firebase as a case study. In this article, we will introduce a better way of managing and securing secrets using Doppler. env files across different environments can be an uphill task. env files are a common method for defining configs and secrets, it gives rise to security risks and the issue of manual management of. # Custom CMD script COPY apache-doppler-start /usr/local/bin/ # Apache site config COPY nf /etc/apache2/sites-enabled/000-default.While.

Most Apache distributions provide a shell script specifically for the purpose of setting environment variables that will be made available to modules such as mod_wsgi. systemd or systemctl), there's a better way. But instead of having to mess with Apache's service manager settings (e.g. When hosting a Python WSGI compatible framework like Django in Apache with mod_wsgi, the only environment variables populated in the os.environ dictionary are those that exist in the environment of the script that starts Apache. Prefer just to read the code? Head to the accompanying repository at Įnvironment Variables, Apache and mod_wsgi That's why I created this step-by-step tutorial and sample application to put all the info you need in one place.Īlthough this tutorial is for Docker and Django, the same steps apply, whether you're using a Virtual Machine or a different Python framework. Using environment variables to configure Django and other Python applications is awesome, but using them with Apache and mod_wsgi in Docker is a tricky thing to get right.
