Encapsulating software within a container brings a lot of benefits, such as quicker deployment, easier development and - last but not least - isolation of your host system from the application.

In this blog post I will show you how to install and configure a VPN client directly inside a docker container without a need of installing anything on your host system.

Thanks to that other computers from a VPN network will have access only to that container and not to your host system!

Because a container has it's own VPN IPv6 network, you can also easily move that container to other hosts without changing anything in your system configuration.

I will show you how to do that in a few easy steps...

In this article I present how to host a web app on your Raspberry Pi (or other computers) with a couple of interesting features.

• ⛔ no static IP address, Dynamic DNS or port forwarding on your router needed
• 🚀 low latency access over the public Internet without server in the middle
• 🔁 possibility to easily share access to that web app only to specific people

The web app will consist of two elements:

• ✏️ front-end: using Bootstrap 4 and websocket client written in JS
• ✏️ back-end: Python app with a websocket server providing a JSON API to the front-end part

I show a bi-directional connection over a single websocket. The demo application will be very simple - controlling a LED connected to Raspberry Pi using a button in web UI and controlling an indicator in the web UI over the button connected to Raspberry Pi.

💭 You can treat this app as a boilerplate code for your own, more sophisticated apps requiring a low-latency control over a web user interface.
