A Definitive Guide to Self-hosting Modmail

Heroku

Setup

1. Fork the repo (Best to make it private).
2. Define a Procfile in the root of the directory and fill the contents with worker: python3 launcher.py.
3. Create a new app on Heroku and deploy the repo you've just forked.
4. Go to "elements" and install the PostgresQL and Redis add-ons to your new app.

Credentials

1. Gather the credentials from the PostgresQL add-on.

2. Go to your config file on your repo and fill in the following credentials:

   # Bot's token
   token = ""
   
   # ...
   
   # Do it unless you want Prometheus
   testing = True
   
   # ...
   
   # Postgres database credentials
   database = {
       # The fields come from the credentials generated
       "database": "",
       "user": "",
       "password": "",
       "host": "",
       "port": 5432,
   }

3. Gather the credentials from the Redis add-on.

4. Go to the config file and set ipc_channel = "" to any name e.g. ipc_channel = "modmail".

5. Navigate to classes/bot.py and modify the redis_pool connection to this format: "redis://<host>:<port>", minsize=5, maxsize=10, loop=self.loop, db=0, password="<password>" (Parts in <> come from the add-on credentials).

6. Deploy to your heroku app.

Database Schema

Note: Make sure you've defined yourself in the owners = [] list in config.py.

1. Open up the schema.sql file cloned from the repo.
2. Navigate to a channel and run the command =sql passing the argument as one table in the schema. You must do all the tables individually or the command will not run e.g. =sql CREATE TABLE public.preference ( identifier bigint NOT NULL, confirmation boolean NOT NULL, PRIMARY KEY (identifier) );.

Deployment

1. Deploy all the changes to GitHub so that the app on Heroku will be updated.
2. On the Heroku app navigate to the Resources tab and there you should see the worker appear under your Dynos.
3. Click the pencil icon and enable the dyno and you are good to go! 🎉
