I would like to enable comments on my blog. Disqus costs money if you don’t want ads and users to be tracked. That’s why I need a self-hosted solution: Commento.

Commento is a fast, privacy-focused commenting platform

It is possible to host Commento for $10/month (https://commento.io). However, this guide is about hosting Commento using Traefik as a reverse proxy. The server should be set up roughly as described here.

Commento needs a database to run. We use Postgres. First, we need a new folder.

cd ~/docker
touch docker-compose-commento.yml
mkdir appdata/commento/db -p
nano docker-compose-commento.yml

What needs to be changed is the domain and the password. That’s it, docker-compose -f docker-compose-commento up -d starts the container. Now, we call up the domain under which Commento is running and create an account. Once the account has been created and in the dashboard, we again enter the command docker-compose -f docker-compose-commento down.

Commento Dashboard

We adjust the settings.

The environment of the Commento server is extended by one entry.

docker-compose -f docker-compose-commento up -d

It should no longer be possible to create a new account with Commento.

Then why are no comments displayed below? Because the GDPR does not allow it without restrictions. Commento still needs an integrated option for users to delete their accounts themselves. Anonymous commenters have no option to enter a name (so everyone is called the same). Anyone can register with any e-mail address. You don’t have to accept a confirmation e-mail.

As a result, I have decided not to add a comment function at this time. 😢

Update:

After some searching, I found the repository of souramoo with Commento++. His fork of Commento at least allows anonymous users to choose a name, eliminating the need for fake mail addresses.

He also responded within a few minutes to my inquiry about whether it would be possible to implement a function allowing users to delete their accounts. This has already been implemented and is available from version 1.8.6.

In any case, it’s time to change the Docker image.

cd ~/docker
docker-compose -f docker-compose-commento.yml down
nano docker-compose-commento.yml

The most significant change is the image from the Commento server.

docker-compose -f docker-compose-commento up -d

The server is now running. Commento++ only needs to be integrated into your own website 🙂
