GetMoarFediverse

This is a small app that shows how you could use FakeRelay to import content into your instance that's tagged with hashtags you're interested in.

This doesn't paginate over the tags, that means it will import up to 20 statuses per instance. This also keeps a txt file with all the statuses it has imported.

Features

GetMoarFediverse can download either from a list of predefined tags or it can connect to you Mastodon's PostgreSQL database and pull the hashtags your users are following.

The FakeRelayApiKey on the config.json is optional. If you don't provide one, you need to pass you FakeRelay key as an environment variable named FAKERELAY_APIKEY.

Pulling from a predefined list of tags

This config.json pulls two tags from two instances:

{
    "FakeRelayUrl": "https://fakerelay.gervas.io",
    "FakeRelayApiKey": "1TxL6m1Esx6tnv4EPxscvAmdQN7qSn0nKeyoM7LD8b9mz+GNfrKaHiWgiT3QcNMUA+dWLyWD8qyl1MuKJ+4uHA==",
    "Tags": [ "dotnet", "csharp" ],
    "Instances": [ "hachyderm.io", "mastodon.social" ]
}

Downloading all the followed hashtags of your instance using the database

You can pass MastodonPostgresConnectionString with a connection string to your postgres database and GetMoarFediverse will download content for all the hashtags the users on your server follow. Here's an example:

{
    "FakeRelayUrl": "https://fakerelay.gervas.io",
    "FakeRelayApiKey": "1TxL6m1Esx6tnv4EPxscvAmdQN7qSn0nKeyoM7LD8b9m+GNfrKaHiWgiT3QcNMUA+dWLyWD8qyl1MuKJ+4uHA==",
    "MastodonPostgresConnectionString": "Host=myserver;Username=mastodon_read;Password=password;Database=mastodon_production",
    "Instances": [ "hachyderm.io", "mastodon.social" ]
}

And download all the hashtags pinned by your users!

If you add "PinnedTags": true, you can also populate the hashtags pinned by your users :) thanks @nberlee, this is great!

{
    "FakeRelayUrl": "https://fakerelay.gervas.io",
    "FakeRelayApiKey": "1TxL6m1Esx6tnv4EPxscvAmdQN7qSn0nKeyoM7LD8b9m+GNfrKaHiWgiT3QcNMUA+dWLyWD8qyl1MuKJ+4uHA==",
    "MastodonPostgresConnectionString": "Host=myserver;Username=mastodon_read;Password=password;Database=mastodon_production",
    "PinnedTags": true,
    "Instances": [ "hachyderm.io", "mastodon.social" ]
}

Downloading the hashtags followed by users via the API

You can pass an Api object and GetMoarFediverse will download content for all the hashtags for each user for whom an access token is provided. Here's an example:

{
  "FakeRelayUrl": "https://foo.example",
  "FakeRelayApiKey": "blah==",
  "Api": {
    "Url": "https://mastodon.example/api/",
    "Tokens": [
      {
        "Owner": "Chris",
        "Token": "1413D6izFoQdu0x00000DZ9ufcBvhOt7hoxuctHg2c"
      }
    ]
  },
  "Instances": [ "hachyderm.io", "mastodon.social" ]
}

For the Tokens array items, both Owner and Token are required fields. Owner can be any non-empty string that would identify the owner of the token (e.g. could be the Mastodon username, app client ID, etc). This data structure allows multiple user accounts to be supported.

To create an access token for the config file, visit the web interface of your Mastodon instance and go to /settings/applications (Settings > Development). The token only requires read:follows scope. Then copy the access token shown at the top of the screen.

If a database connection string is also provided via MastodonPostgresConnectionString, the tags will be retrieved via the database and any API-related settings will be ignored.

How can I run it?

There are many ways for you to run GetMoarFediverse:

Running it as a GitHub Action

I recommend you watch this demo I recorded. Basically you can run GetMoarFediverse as a GitHub Action, so that you don't have to think about setting anything up on your infrastructure:

  1. Fork GMFActionDemo
  2. Change the config.json so that you pull the tags you want
  3. Add a FAKERELAY_APIKEY GitHub Action secret with your api key
  4. Uncomment the two lines on GetMoarFediverse.yml that run it on a scheduled route. Keep in mind that the schedule event can be delayed during periods of high loads of GitHub Actions workflow runs.

This was built and graciously shared back to the main repo by @chdorner. Thanks a ton!

Download a prebuilt executable

You can download an executable for your environment on the releases page. In addition to that, you will need to create a config.json file with your desired logic. Once you have that file, all you need to run is ./GetMoarFediverse /path/to/config.json. You can put it on a cron like this :)

1,16,31,46 * * * * /path/to/GetMoarFediverse /path/to/config.json > /path/to/GetMoarFediverse/cron.log 2>&1

You will find an executable for Windows as well, which you can use on a scheduled task.

You can run it on docker

You can use docker compose for this. This docker-compose.yml shows how it can be used:

version: '2'
services:
  importdata:
    image: 'ghcr.io/g3rv4/getmoarfediverse:latest'
    volumes:
      - '/path/to/GetMoarFediverse/data:/data'

On /path/to/GetMoarFediverse/data, you need to place a config.json that tells the system what you want.

Once you have that set up, you can just execute it! and it will output what's going on.

g3rv4@s1:~/docker/FakeRelay$ docker-compose run --rm importdata
Fetching tag #dotnet from mastodon.social
Fetching tag #hachyderm from hachyderm.io

Fetching tag #csharp from mastodon.social
Fetching tag #csharp from hachyderm.io
Bringing in https://dotnet.social/users/mzikmund/statuses/109458968117245196

You can run it as a cron every 15 minutes, doing something like this:

1,16,31,46 * * * * /usr/local/bin/docker-compose -f /path/to/GetMoarFediverse/docker-compose.yml run --rm importdata > /path/to/GetMoarFediverse/cron.log 2>&1
