Create a Flask+uWSGI+Nginx Docker Image

In this example, we will create a Docker image for a Flask application using uWSGI and Nginx. The image will be based on the tiangolo/uwsgi-nginx-flask image, which is a popular choice for deploying Flask applications in production.

Introduction

This guide outlines the steps to set up an OpenVPN server on Ubuntu 24.04, including certificate management, server configuration, firewall setup, and client provisioning.

Introduction

After enabling the OpenVPN server on an ASUS router, the exported client.ovpn file may trigger the following error in the OpenVPN client on Android:

1

OpenSSL: error:0A00018E:SSL routines:SSL_CTX_use_certificate:ca md too weak

This issue occurs because the CA certificate uses the SHA1 signature algorithm, which is outdated and considered insecure. Consequently, the OpenVPN client refuses to accept it.

There are two possible solutions:

1. Insecure (Not Recommended): Allow weak CA certificates.
2. Recommended: Renew the CA certificate using a stronger signature algorithm (e.g., SHA256 or higher).

Allowing weak certificates may expose your connection to man-in-the-middle (MITM) attacks or other vulnerabilities.

This guide walks you through the recommended solution.

FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams.
