    The project website list a few use cases for real life and I like them, but I will share another use case.

    ssss project website

    I used to run a community but there was no person in charge apart me, which made me a single point of failure. I decided to make the encrypted backup available to a few kind of trustable community members, and I gave each a secret. There were four members and I made the backup password available only if the four members agreed to share their secrets to get the password. For privacy reasons, I didn't want any of these people to be able to lurk into the backup, at least, if someone had happened to me, they could agree to recover the database only if the four persons agreed on it.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
