1 # Configuration Cheat Sheet
3 This is a cheat sheet for Pleroma configuration file, any setting possible to configure should be listed here.
5 For OTP installations the configuration is typically stored in `/etc/pleroma/config.exs`.
7 For from source installations Pleroma configuration works by first importing the base config `config/config.exs`, then overriding it by the environment config `config/$MIX_ENV.exs` and then overriding it by user config `config/$MIX_ENV.secret.exs`. In from source installations you should always make the changes to the user config and NEVER to the base config to avoid breakages and merge conflicts. So for production you change/add configuration to `config/prod.secret.exs`.
9 To add configuration to your config file, you can copy it from the base config. The latest version of it can be viewed [here](https://git.pleroma.social/pleroma/pleroma/blob/develop/config/config.exs). You can also use this file if you don't know how an option is supposed to be formatted.

500 * `:max_connections` - Maximum number of connections in the pool.
501 * `:connect_timeout` - Timeout to connect to the host.
502 * `:reclaim_multiplier` - Multiplied by `:max_connections` this will be the maximum number of idle connections that will be reclaimed in case the pool is overloaded.
508 Settings for request pools. These pools are limited on top of `:connections_pool`.
510 There are four pools used:
512 * `:federation` for the federation jobs. You may want this pool's max_connections to be at least equal to the number of federator jobs + retry queue jobs.
513 * `:media` - for rich media, media proxy.
514 * `:upload` - for proxying media when a remote uploader is used and `proxy_remote: true`.
515 * `:default` - for other requests.
517 For each pool, the options are:
519 * `:size` - limit to how much requests can be concurrently executed.
520 * `:recv_timeout` - timeout while `gun` will wait for response
521 * `:max_waiting` - limit to how much requests can be waiting for others to finish, after this is reached, subsequent requests will be dropped.
527 * `enabled`: Whether the captcha should be shown on registration.
528 * `method`: The method/service to use for captcha.
529 * `seconds_valid`: The time in seconds for which the captcha is valid.
531 ### Captcha providers
533 #### Pleroma.Captcha.Native
535 A built-in captcha provider. Enabled by default.
537 #### Pleroma.Captcha.Kocaptcha
539 Kocaptcha is a very simple captcha service with a single API endpoint,
540 the source code is here: [kocaptcha](https://github.com/koto-bank/kocaptcha). The default endpoint
541 `https://captcha.kotobank.ch` is hosted by the developer.
543 * `endpoint`: the Kocaptcha endpoint to use.
549 * `uploader`: Which one of the [uploaders](#uploaders) to use.
550 * `filters`: List of [upload filters](#upload-filters) to use.
551 * `link_name`: When enabled Pleroma will add a `name` parameter to the url of the upload, for example `https://instance.tld/media/corndog.png?name=corndog.png`. This is needed to provide the correct filename in Content-Disposition headers when using filters like `Pleroma.Upload.Filter.Dedupe`
552 * `base_url`: The base URL to access a user-uploaded file. Useful when you want to host the media files via another domain or are using a 3rd party S3 provider.
553 * `proxy_remote`: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
554 * `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
555 * `filename_display_max_length`: Set max length of a filename to display. 0 = no limit. Default: 30.
556 * `default_description`: Sets which default description an image has if none is set explicitly. Options: nil (default) - Don't set a default, :filename - use the filename of the file, a string (e.g. "attachment") - Use this string
559 `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.
563 #### Pleroma.Uploaders.Local
565 * `uploads`: Which directory to store the user-uploads in, relative to pleroma’s working directory.
567 #### Pleroma.Uploaders.S3
569 Don't forget to configure [Ex AWS S3](#ex-aws-s3-settings)
571 * `bucket`: S3 bucket name.
572 * `bucket_namespace`: S3 bucket namespace.
573 * `truncated_namespace`: If you use S3 compatible service such as Digital Ocean Spaces or CDN, set folder name or "" etc.
574 * `streaming_enabled`: Enable streaming uploads, when enabled the file will be sent to the server in chunks as it's being read. This may be unsupported by some providers, try disabling this if you have upload problems.
576 #### Ex AWS S3 settings
578 * `access_key_id`: Access key ID
579 * `secret_access_key`: Secret access key
586 access_key_id: "xxxxxxxxxx",
587 secret_access_key: "yyyyyyyyyy",
588 host: "s3.eu-central-1.amazonaws.com"
593 #### Pleroma.Upload.Filter.AnonymizeFilename
595 This filter replaces the filename (not the path) of an upload. For complete obfuscation, add
596 `Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.
598 * `text`: Text to replace filenames in links. If empty, `{random}.extension` will be used. You can get the original filename extension by using `{extension}`, for example `custom-file-name.{extension}`.
600 #### Pleroma.Upload.Filter.Dedupe
602 No specific configuration.
604 #### Pleroma.Upload.Filter.Exiftool
606 This filter only strips the GPS and location metadata with Exiftool leaving color profiles and attributes intact.
608 No specific configuration.
610 #### Pleroma.Upload.Filter.Mogrify
612 * `args`: List of actions for the `mogrify` command like `"strip"` or `["strip", "auto-orient", {"implode", "1"}]`.
616 ### Pleroma.Emails.Mailer

618 * `api_key` / `password` and / or other adapter-specific settings, per the above documentation.
619 * `enabled`: Allows enable/disable send emails. Default: `false`.
621 An example for Sendgrid adapter:
624 config :pleroma, Pleroma.Emails.Mailer,
626 adapter: Swoosh.Adapters.Sendgrid,
627 api_key: "YOUR_API_KEY"
630 An example for SMTP adapter:
633 config :pleroma, Pleroma.Emails.Mailer,
635 adapter: Swoosh.Adapters.SMTP,
636 relay: "smtp.gmail.com",
637 username: "YOUR_USERNAME@gmail.com",
638 password: "YOUR_SMTP_PASSWORD",
644 ### :email_notifications
646 Email notifications settings.
648 - digest - emails of "what you've missed" for users who have been
649 inactive for a while.
650 - active: globally enable or disable digest emails
651 - schedule: When to send digest email, in [crontab format](https://en.wikipedia.org/wiki/Cron).
652 "0 0 * * 0" is the default, meaning "once a week at midnight on Sunday morning"

654 - inactivity_threshold: Minimum user inactivity threshold
656 ### Pleroma.Emails.UserEmail
658 - `:logo` - a path to a custom logo. Set it to `nil` to use the default Pleroma logo.
659 - `:styling` - a map with color settings for email templates.
661 ### Pleroma.Emails.NewUsersDigestEmail
663 - `:enabled` - a boolean, enables new users admin digest email when `true`. Defaults to `false`.
669 [Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
671 Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
673 * `repo` - app's Ecto repo (`Pleroma.Repo`)
674 * `log` - logs verbosity
675 * `queues` - job queues (see below)
676 * `crontab` - periodic jobs, see [`Oban.Cron`](#obancron)
678 Pleroma has the following queues:
680 * `activity_expiration` - Activity expiration
681 * `federator_outgoing` - Outgoing federation
682 * `federator_incoming` - Incoming federation
683 * `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
684 * `transmogrifier` - Transmogrifier
685 * `web_push` - Web push notifications
686 * `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
690 Pleroma has these periodic job workers:
692 * `Pleroma.Workers.Cron.DigestEmailsWorker` - digest emails for users with new mentions and follows
693 * `Pleroma.Workers.Cron.NewUsersDigestWorker` - digest emails for admins with new registrations
696 config :pleroma, Oban,
699 prune: {:maxlen, 1500},
701 federator_incoming: 50,
702 federator_outgoing: 50
705 {"0 0 * * 0", Pleroma.Workers.Cron.DigestEmailsWorker},
706 {"0 0 * * *", Pleroma.Workers.Cron.NewUsersDigestWorker}
710 This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
712 #### Migrating `pleroma_job_queue` settings
714 `config :pleroma_job_queue, :queues` is replaced by `config :pleroma, Oban, :queues` and uses the same format (keys are queues' names, values are max concurrent jobs numbers).
718 Includes custom worker options not interpretable directly by `Oban`.
720 * `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
725 config :pleroma, :workers,
727 federator_incoming: 5,
728 federator_outgoing: 5
732 #### Migrating `Pleroma.Web.Federator.RetryQueue` settings
734 * `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
735 * `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
736 * deprecated options: `max_jobs`, `initial_timeout`
738 ## :web_push_encryption, :vapid_details
740 Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
742 * ``subject``: a mailto link for the administrative contact. It’s best if this email is not a personal email address, but rather a group email so that if a person leaves an organization, is unavailable for an extended period, or otherwise can’t respond, someone else on the list can.
743 * ``public_key``: VAPID public key
744 * ``private_key``: VAPID private key
747 * `backends`: `:console` is used to send logs to stdout, `{ExSyslogger, :ex_syslogger}` to log to syslog, and `Quack.Logger` to log to Slack
749 An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
752 backends: [{ExSyslogger, :ex_syslogger}]
754 config :logger, :ex_syslogger,
758 Another example, keeping console output and adding the pid to syslog output:
761 backends: [:console, {ExSyslogger, :ex_syslogger}]
763 config :logger, :ex_syslogger,
765 option: [:pid, :ndelay]
768 See: [logger’s documentation](https://hexdocs.pm/logger/Logger.html) and [ex_syslogger’s documentation](https://hexdocs.pm/ex_syslogger/)
770 An example of logging info to local syslog, but warn to a Slack channel:
773 backends: [ {ExSyslogger, :ex_syslogger}, Quack.Logger ],
776 config :logger, :ex_syslogger,
779 format: "$metadata[$level] $message"
784 webhook_url: "https://hooks.slack.com/services/YOUR-API-KEY-HERE"
787 See the [Quack Github](https://github.com/azohra/quack) for more details
793 ### RUM indexing for full text search
796 It is recommended to use PostgreSQL v11 or newer. We have seen some minor issues with lower PostgreSQL versions.
798 * `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
800 RUM indexes are an alternative indexing scheme that is not included in PostgreSQL by default. While they may eventually be mainlined, for now they have to be installed as a PostgreSQL extension from https://github.com/postgrespro/rum.
802 Their advantage over the standard GIN indexes is that they allow efficient ordering of search results by timestamp, which makes search queries a lot faster on larger servers, by one or two orders of magnitude. They take up around 3 times as much space as GIN indexes.
804 To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
806 `mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
808 This will probably take a long time.
810 ## Alternative client protocols
814 To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
818 priv_dir = Path.join([app_dir, "priv/ssh_keys"])
823 handler: "Pleroma.BBS.Handler",
825 password_authenticator: "Pleroma.BBS.Authenticator"
828 Feel free to adjust the priv_dir and port number. Then you will have to create the key for the keys (in the example `priv/ssh_keys`) and create the host keys with `ssh-keygen -m PEM -N "" -b 2048 -t rsa -f ssh_host_rsa_key`. After restarting, you should be able to connect to your Pleroma instance with `ssh username@server -p $PORT`
831 * `enabled`: Enables the gopher interface
832 * `ip`: IP address to bind to
833 * `port`: Port to bind to
834 * `dstport`: Port advertised in urls (optional, defaults to `port`)
841 Allows to set a token that can be used to authenticate with the admin api without using an actual user by giving it as the `admin_token` parameter or `x-admin-token` HTTP header. Example:
844 config :pleroma, :admin_token, "somerandomtoken"
850 curl "http://localhost:4000/api/pleroma/admin/users/invites?admin_token=somerandomtoken"
856 curl -H "X-Admin-Token: somerandomtoken" "http://localhost:4000/api/pleroma/admin/users/invites"
859 Warning: it's discouraged to use this feature because of the associated security risk: static / rarely changed instance-wide token is much weaker compared to email-password pair of a real admin user; consider using HTTP Basic Auth or OAuth-based authentication instead.
863 Authentication / authorization settings.
865 * `auth_template`: authentication form template. By default it's `show.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/show.html.eex`.
866 * `oauth_consumer_template`: OAuth consumer mode authentication form template. By default it's `consumer.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/consumer.html.eex`.
867 * `oauth_consumer_strategies`: the list of enabled OAuth consumer strategies; by default it's set by `OAUTH_CONSUMER_STRATEGIES` environment variable. Each entry in this space-delimited string should be of format `<strategy>` or `<strategy>:<dependency>` (e.g. `twitter` or `keycloak:ueberauth_keycloak_strategy` in case dependency is named differently than `ueberauth_<strategy>`).
869 ### Pleroma.Web.Auth.Authenticator
871 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
872 * `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
876 Use LDAP for user authentication. When a user logs in to the Pleroma
877 instance, the name and password will be verified by trying to authenticate
878 (bind) to an LDAP server. If a user exists in the LDAP directory but there
879 is no account with the same name yet on the Pleroma instance then a new
880 Pleroma account will be created with the same name as the LDAP user name.
882 * `enabled`: enables LDAP authentication
883 * `host`: LDAP server hostname
884 * `port`: LDAP port, e.g. 389 or 636
885 * `ssl`: true to use SSL, usually implies the port 636
886 * `sslopts`: additional SSL options
887 * `tls`: true to start TLS, usually implies the port 389
888 * `tlsopts`: additional TLS options
889 * `base`: LDAP base, e.g. "dc=example,dc=com"
890 * `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
892 Note, if your LDAP server is an Active Directory server the correct value is commonly `uid: "cn"`, but if you use an
893 OpenLDAP server the value may be `uid: "uid"`.
895 ### OAuth consumer mode
897 OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
898 Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
901 Each strategy is shipped as a separate dependency; in order to get the strategies, run `OAUTH_CONSUMER_STRATEGIES="..." mix deps.get`, e.g. `OAUTH_CONSUMER_STRATEGIES="twitter facebook google microsoft" mix deps.get`. The server should also be started with `OAUTH_CONSUMER_STRATEGIES="..." mix phx.server` in case you enable any strategies.
904 Each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
907 Make sure that `"SameSite=Lax"` is set in `extra_cookie_attrs` when you have this feature enabled. OAuth consumer mode will not work with `"SameSite=Strict"`
909 * For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
911 * For Facebook, [register an app](https://developers.facebook.com/apps), configure callback URL to https://<your_host>/oauth/facebook/callback, enable Facebook Login service at https://developers.facebook.com/apps/<app_id>/fb-login/settings/
913 * For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
915 * For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
917 Once the app is configured on external OAuth provider side, add app's credentials and strategy-specific settings (if any — e.g. see Microsoft below) to `config/prod.secret.exs`,
918 per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
922 config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
923 consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
924 consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
927 config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
928 client_id: System.get_env("FACEBOOK_APP_ID"),
929 client_secret: System.get_env("FACEBOOK_APP_SECRET"),
930 redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
933 config :ueberauth, Ueberauth.Strategy.Google.OAuth,
934 client_id: System.get_env("GOOGLE_CLIENT_ID"),
935 client_secret: System.get_env("GOOGLE_CLIENT_SECRET"),
936 redirect_uri: System.get_env("GOOGLE_REDIRECT_URI")
939 config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
940 client_id: System.get_env("MICROSOFT_CLIENT_ID"),
941 client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
943 config :ueberauth, Ueberauth,
945 microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
949 # Note: make sure to add `keycloak:ueberauth_keycloak_strategy` entry to `OAUTH_CONSUMER_STRATEGIES` environment variable
950 keycloak_url = "https://publicly-reachable-keycloak-instance.org:8080"
952 config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
953 client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
954 client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),
956 authorize_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/auth",
957 token_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/token",
958 userinfo_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/userinfo",
961 config :ueberauth, Ueberauth,
963 keycloak: {Ueberauth.Strategy.Keycloak, [uid_field: :email]}
967 ### OAuth 2.0 provider - :oauth2
969 Configure OAuth 2 provider capabilities:
971 * `token_expires_in` - The lifetime in seconds of the access token.
972 * `issue_new_refresh_token` - Keeps old refresh token or generate new refresh token when to obtain an access token.
973 * `clean_expired_tokens` - Enable a background job to clean expired oauth tokens. Defaults to `false`.
978 * `valid_schemes`: List of the scheme part that is considered valid to be an URL.
980 ### Pleroma.Formatter
982 Configuration for Pleroma's link formatter which parses mentions, hashtags, and URLs.
984 * `class` - specify the class to be added to the generated link (default: `false`)
985 * `rel` - specify the rel attribute (default: `ugc`)
986 * `new_window` - adds `target="_blank"` attribute (default: `false`)
987 * `truncate` - Set to a number to truncate URLs longer then the number. Truncated URLs will end in `...` (default: `false`)
988 * `strip_prefix` - Strip the scheme prefix (default: `false`)
989 * `extra` - link URLs with rarely used schemes (magnet, ipfs, irc, etc.) (default: `true`)
990 * `validate_tld` - Set to false to disable TLD validation for URLs/emails. Can be set to :no_scheme to validate TLDs only for urls without a scheme (e.g `example.com` will be validated, but `http://example.loki` won't) (default: `:no_scheme`)
995 config :pleroma, Pleroma.Formatter,
1000 strip_prefix: false,
1002 validate_tld: :no_scheme
1005 ## Custom Runtime Modules (`:modules`)
1007 * `runtime_dir`: A path to custom Elixir modules (such as MRF policies).
1009 ## :configurable_from_database
1011 Boolean, enables/disables in-database configuration. Read [Transfering the config to/from the database](../administration/CLI_tasks/config.md) for more information.
1013 ## :database_config_whitelist
1015 List of valid configuration sections which are allowed to be configured from the
1016 database. Settings stored in the database before the whitelist is configured are
1017 still applied, so it is suggested to only use the whitelist on instances that
1018 have not migrated the config to the database.
1022 config :pleroma, :database_config_whitelist, [
1023 {:pleroma, :instance},
1024 {:pleroma, Pleroma.Web.Metadata},
1029 ### Multi-factor authentication - :two_factor_authentication
1030 * `totp` - a list containing TOTP configuration
1031 - `digits` - Determines the length of a one-time pass-code in characters. Defaults to 6 characters.
1032 - `period` - a period for which the TOTP code will be valid in seconds. Defaults to 30 seconds.
1033 * `backup_codes` - a list containing backup codes configuration
1034 - `number` - number of backup codes to generate.
1035 - `length` - backup code length. Defaults to 16 characters.
1037 ## Restrict entities access for unauthenticated users
1039 ### :restrict_unauthenticated
1041 Restrict access for unauthenticated users to timelines (public and federated), user profiles and statuses.
1043 * `timelines`: public and federated timelines
1044 * `local`: public timeline
1045 * `federated`: federated timeline (includes public timeline)
1046 * `profiles`: user profiles
1049 * `activities`: statuses
1053 Note: when `:instance, :public` is set to `false`, all `:restrict_unauthenticated` items be effectively set to `true` by default. If you'd like to allow unauthenticated access to specific API endpoints on a private instance, please explicitly set `:restrict_unauthenticated` to non-default value in `config/prod.secret.exs`.
1055 Note: setting `restrict_unauthenticated/timelines/local` to `true` has no practical sense if `restrict_unauthenticated/timelines/federated` is set to `false` (since local public activities will still be delivered to unauthenticated users as part of federated timeline).
1057 ## Pleroma.Web.ApiSpec.CastAndValidate
1059 * `:strict` a boolean, enables strict input validation (useful in development, not recommended in production). Defaults to `false`.
1061 ## :instances_favicons
1063 Control favicons for instances.
1065 * `enabled`: Allow/disallow displaying and getting instances favicons
1067 ## Pleroma.User.Backup
1070 Requires enabled email
1072 * `:purge_after_days` an integer, remove backup achives after N days.
1073 * `:limit_days` an integer, limit user to export not more often than once per N days.
1074 * `:dir` a string with a path to backup temporary directory or `nil` to let Pleroma choose temporary directory in the following order:
1075 1. the directory named by the TMPDIR environment variable
1076 2. the directory named by the TEMP environment variable
1077 3. the directory named by the TMP environment variable
1078 4. C:\TMP on Windows or /tmp on Unix-like operating systems
1079 5. as a last resort, the current working directory
1081 ## Frontend management
1083 Frontends in Pleroma are swappable - you can specify which one to use here.
1085 You can set a frontends for the key `primary` and `admin` and the options of `name` and `ref`. This will then make Pleroma serve the frontend from a folder constructed by concatenating the instance static path, `frontends` and the name and ref.
1087 The key `primary` refers to the frontend that will be served by default for general requests. The key `admin` refers to the frontend that will be served at the `/pleroma/admin` path.
1089 If you don't set anything here, the bundled frontends will be used.
1094 config :pleroma, :frontends,
1096 "name" => "pleroma",
1105 This would serve the frontend from the the folder at `$instance_static/frontends/pleroma/stable`. You have to copy the frontend into this folder yourself. You can choose the name and ref any way you like, but they will be used by mix tasks to automate installation in the future, the name referring to the project and the ref referring to a commit.
1107 ## Ephemeral activities (Pleroma.Workers.PurgeExpiredActivity)
1109 Settings to enable and configure expiration for ephemeral activities
1111 * `:enabled` - enables ephemeral activities creation
1112 * `:min_lifetime` - minimum lifetime for ephemeral activities (in seconds). Default: 10 minutes.
1114 ## ConcurrentLimiter
1116 Settings to restrict concurrently running jobs. Jobs which can be configured:
1118 * `Pleroma.Web.RichMedia.Helpers` - generating link previews of URLs in activities
1119 * `Pleroma.Web.MediaProxy` - fetching remote media via MediaProxy
1121 Each job has these settings:
1123 * `:max_running` - max concurrently runnings jobs
1124 * `:max_waiting` - max waiting jobs
