Coral Talk is a comment and moderation system from Mozilla. It is part of the Coral project which proclaims that it wants to improve journalism. I'm no journalist, but I found their comment system interesting for four particular reasons:
- It is open source and backed by mozilla
- It is self hosted which means
- I own my own data
- Users won't have their comments become ad targeting food
- It has a simple admin and moderation dashboard
- It is based on a plugin architecture which allows anyone including me to easily extend its functionality
I had previously set up isso on my blog, but the lack of a moderation system not relying on smtp meant I would have to trust Internet users not to post obscene content or spam in my comment section. That said, isso is an excellent little comment server. If you have an smtp server set up the built in moderation feature might work for you.
Talk checks some of the same checkboxes isso does. It is open source, self hosted, etc. It does however come at a greater resource cost using both mongodb and redis to store and cache content where isso just uses sqlite. It does not allow anonymous comments either, which is something that might stop people from commenting all together. I did receive some comments in my old isso installation. It will be interesting to see if anyone bothers creating a user to comment on any of my posts.
Running Coral Talk with Docker
As you might have surmised I'm a fan of Docker. Docker allows you to quite easily run software without worrying about dependencies and process managers. The Talk project provides an Installation from Docker guide which will get you started. Essentially you can host it using a docker-compose setup where talk, mongodb, and redis is configured. My current setup looks like this:
version: "3" services: talk: build: ./talk restart: unless-stopped ports: - 80:3000 depends_on: - mongo - redis networks: - talk environment: - TALK_MONGO_URL=mongodb://mongo/talk - TALK_REDIS_URL=redis://redis - TALK_ROOT_URL=https://talk.<yourdomain>.tld - TALK_PORT=3000 - TALK_JWT_SECRET=<your-super-secret-jwt-secret> logging: driver: "json-file" options: max-size: "512k" max-file: "10" mongo: image: mongo:latest restart: unless-stopped volumes: - mongo:/data/db networks: - talk logging: driver: "json-file" options: max-size: "512k" max-file: "10" redis: image: redis:latest restart: unless-stopped volumes: - redis:/data networks: - talk logging: driver: "json-file" options: max-size: "512k" max-file: "10" volumes: mongo: redis: networks: talk:
build: ./talk section under the
talk service. Because I'm not a big fan of Facebook login and setting up a Facebook app and api key just to use a comment system I decided to modify the default Talk docker image and not load the Facebook authentication plugin. My
Dockerfile to accomplish this is included below. The command simply removes the config line containing the facebook auth plugin.
FROM coralproject/talk:4-onbuild RUN sed -i '/talk-plugin-facebook-auth/d' ./plugins.default.json
This allows me to build an image where the Facebook authentication plugin is not activated and thus I do not have to setup a Facebook application just to use the Talk comment system. Setting up Talk using Docker proved to be quite easy.
In conclusion I think Talk will serve me quite nicely. There are still features I have yet to try like the toxic-comments plugin, authoring my own plugins, and of course creating a custom style. But everything in due time.
