1 # Configuration Cheat Sheet
2
3 This is a cheat sheet for Pleroma configuration file, any setting possible to configure should be listed here.
4
5 For OTP installations the configuration is typically stored in `/etc/pleroma/config.exs`.
6
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`.
8
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.

320
321 ### :rate_limit
322
323 !!! note
324 If your instance is behind a reverse proxy ensure [`Pleroma.Plugs.RemoteIp`](#pleroma-plugs-remoteip) is enabled (it is enabled by default).
325
326 A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
327
328 * The first element: `scale` (Integer). The time scale in milliseconds.
329 * The second element: `limit` (Integer). How many requests to limit in the time scale provided.
330
331 It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
332
333 For example:
334
335 ```elixir
336 config :pleroma, :rate_limit,
337 authentication: {60_000, 15},
338 search: [{1000, 10}, {1000, 30}]
339 ```
340
341 Means that:
342
343 1. In 60 seconds, 15 authentication attempts can be performed from the same IP address.
344 2. In 1 second, 10 search requests can be performed from the same IP adress by unauthenticated users, while authenticated users can perform 30 search requests per second.
345
346 Supported rate limiters:
347
348 * `:search` - Account/Status search.
349 * `:timeline` - Timeline requests (each timeline has it's own limiter).
350 * `:app_account_creation` - Account registration from the API.
351 * `:relations_actions` - Following/Unfollowing in general.
352 * `:relation_id_action` - Following/Unfollowing for a specific user.
353 * `:statuses_actions` - Status actions such as: (un)repeating, (un)favouriting, creating, deleting.
354 * `:status_id_action` - (un)Repeating/(un)Favouriting a particular status.
355 * `:authentication` - Authentication actions, i.e getting an OAuth token.
356 * `:password_reset` - Requesting password reset emails.
357 * `:account_confirmation_resend` - Requesting resending account confirmation emails.
358 * `:ap_routes` - Requesting statuses via ActivityPub.
359
360 ### :web_cache_ttl
361
362 The expiration time for the web responses cache. Values should be in milliseconds or `nil` to disable expiration.
363
364 Available caches:
365
366 * `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
367 * `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).
368
369 ## HTTP client
370
371 ### :http
372
373 * `proxy_url`: an upstream proxy to fetch posts and/or media with, (default: `nil`)
374 * `send_user_agent`: should we include a user agent with HTTP requests? (default: `true`)
375 * `user_agent`: what user agent should we use? (default: `:default`), must be string or `:default`
376 * `adapter`: array of adapter options
377
378 ### :hackney_pools
379
380 Advanced. Tweaks Hackney (http client) connections pools.
381
382 There's three pools used:
383
384 * `:federation` for the federation jobs.
385 You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
386 * `:media` for rich media, media proxy
387 * `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
388
389 For each pool, the options are:
390
391 * `max_connections` - how much connections a pool can hold
392 * `timeout` - retention duration for connections
393
394
395 ### :connections_pool
396
397 *For `gun` adapter*
398
399 Advanced settings for connections pool. Pool with opened connections. These connections can be reused in worker pools.
400
401 For big instances it's recommended to increase `config :pleroma, :connections_pool, max_connections: 500` up to 500-1000.
402 It will increase memory usage, but federation would work faster.
403
404 * `:checkin_timeout` - timeout to checkin connection from pool. Default: 250ms.
405 * `:max_connections` - maximum number of connections in the pool. Default: 250 connections.
406 * `:retry` - number of retries, while `gun` will try to reconnect if connection goes down. Default: 1.
407 * `:retry_timeout` - time between retries when `gun` will try to reconnect in milliseconds. Default: 1000ms.
408 * `:await_up_timeout` - timeout while `gun` will wait until connection is up. Default: 5000ms.
409
410 ### :pools
411
412 *For `gun` adapter*
413
414 Advanced settings for workers pools.
415
416 There are four pools used:
417
418 * `:federation` for the federation jobs.
419 You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
420 * `:media` for rich media, media proxy
421 * `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
422 * `:default` for other requests
423
424 For each pool, the options are:
425
426 * `:size` - how much workers the pool can hold
427 * `:timeout` - timeout while `gun` will wait for response
428 * `:max_overflow` - additional workers if pool is under load
429
430
431 ## Captcha
432
433 ### Pleroma.Captcha
434
435 * `enabled`: Whether the captcha should be shown on registration.
436 * `method`: The method/service to use for captcha.
437 * `seconds_valid`: The time in seconds for which the captcha is valid.
438
439 ### Captcha providers
440
441 #### Pleroma.Captcha.Native
442
443 A built-in captcha provider. Enabled by default.
444
445 #### Pleroma.Captcha.Kocaptcha
446
447 Kocaptcha is a very simple captcha service with a single API endpoint,
448 the source code is here: https://github.com/koto-bank/kocaptcha. The default endpoint
449 `https://captcha.kotobank.ch` is hosted by the developer.
450
451 * `endpoint`: the Kocaptcha endpoint to use.
452
453 ## Uploads
454
455 ### Pleroma.Upload
456 * `uploader`: Which one of the [uploaders](#uploaders) to use.
457 * `filters`: List of [upload filters](#upload-filters) to use.
458 * `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`
459 * `base_url`: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
460 * `proxy_remote`: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
461 * `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
462
463 !!! warning
464 `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.
465
466 ### Uploaders
467 #### Pleroma.Uploaders.Local
468 * `uploads`: Which directory to store the user-uploads in, relative to pleroma’s working directory.

472 * `bucket_namespace`: S3 bucket namespace.
473 * `public_endpoint`: S3 endpoint that the user finally accesses(ex. "https://s3.dualstack.ap-northeast-1.amazonaws.com")
474 * `truncated_namespace`: If you use S3 compatible service such as Digital Ocean Spaces or CDN, set folder name or "" etc.
475 For example, when using CDN to S3 virtual host format, set "".
476 At this time, write CNAME to CDN in public_endpoint.
477 * `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.
478
479
480 ### Upload filters
481
482 #### Pleroma.Upload.Filter.Mogrify

487
488 No specific configuration.
489
490 #### Pleroma.Upload.Filter.AnonymizeFilename
491
492 This filter replaces the filename (not the path) of an upload. For complete obfuscation, add
493 `Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.
494
495 * `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}`.
496
497 ## Email
498
499 ### Pleroma.Emails.Mailer
500 * `adapter`: one of the mail adapters listed in [Swoosh readme](https://github.com/swoosh/swoosh#adapters), or `Swoosh.Adapters.Local` for in-memory mailbox.
501 * `api_key` / `password` and / or other adapter-specific settings, per the above documentation.
502 * `enabled`: Allows enable/disable send emails. Default: `false`.
503
504 An example for Sendgrid adapter:
505
506 ```elixir
507 config :pleroma, Pleroma.Emails.Mailer,
508 enabled: true,
509 adapter: Swoosh.Adapters.Sendgrid,
510 api_key: "YOUR_API_KEY"
511 ```
512
513 An example for SMTP adapter:

547
548 ## Background jobs
549
550 ### Oban
551
552 [Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
553
554 Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
555
556 * `repo` - app's Ecto repo (`Pleroma.Repo`)
557 * `verbose` - logs verbosity
558 * `prune` - non-retryable jobs [pruning settings](https://github.com/sorentwo/oban#pruning) (`:disabled` / `{:maxlen, value}` / `{:maxage, value}`)
559 * `queues` - job queues (see below)
560 * `crontab` - periodic jobs, see [`Oban.Cron`](#obancron)
561
562 Pleroma has the following queues:
563
564 * `activity_expiration` - Activity expiration
565 * `federator_outgoing` - Outgoing federation
566 * `federator_incoming` - Incoming federation
567 * `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
568 * `transmogrifier` - Transmogrifier
569 * `web_push` - Web push notifications
570 * `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
571
572 #### Oban.Cron
573
574 Pleroma has these periodic job workers:
575
576 `Pleroma.Workers.Cron.ClearOauthTokenWorker` - a job worker to cleanup expired oauth tokens.
577
578 Example:
579
580 ```elixir
581 config :pleroma, Oban,
582 repo: Pleroma.Repo,
583 verbose: false,
584 prune: {:maxlen, 1500},
585 queues: [
586 federator_incoming: 50,
587 federator_outgoing: 50
588 ],
589 crontab: [
590 {"0 0 * * *", Pleroma.Workers.Cron.ClearOauthTokenWorker}
591 ]
592 ```
593
594 This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
595
596 #### Migrating `pleroma_job_queue` settings
597
598 `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).
599
600 ### :workers
601
602 Includes custom worker options not interpretable directly by `Oban`.
603
604 * `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
605
606 Example:
607
608 ```elixir
609 config :pleroma, :workers,
610 retries: [
611 federator_incoming: 5,
612 federator_outgoing: 5
613 ]
614 ```
615
616 #### Migrating `Pleroma.Web.Federator.RetryQueue` settings
617
618 * `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
619 * `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
620 * deprecated options: `max_jobs`, `initial_timeout`
621
622 ### Pleroma.Scheduler
623
624 Configuration for [Quantum](https://github.com/quantum-elixir/quantum-core) jobs scheduler.
625
626 See [Quantum readme](https://github.com/quantum-elixir/quantum-core#usage) for the list of supported options.
627
628 Example:
629
630 ```elixir
631 config :pleroma, Pleroma.Scheduler,
632 global: true,
633 overlap: true,
634 timezone: :utc,
635 jobs: [{"0 */6 * * * *", {Pleroma.Web.Websub, :refresh_subscriptions, []}}]
636 ```
637
638 The above example defines a single job which invokes `Pleroma.Web.Websub.refresh_subscriptions()` every 6 hours ("0 */6 * * * *", [crontab format](https://en.wikipedia.org/wiki/Cron)).
639
640 ## :web_push_encryption, :vapid_details
641
642 Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
643
644 * ``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.
645 * ``public_key``: VAPID public key
646 * ``private_key``: VAPID private key
647
648 ## :logger
649 * `backends`: `:console` is used to send logs to stdout, `{ExSyslogger, :ex_syslogger}` to log to syslog, and `Quack.Logger` to log to Slack
650
651 An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
652 ```elixir
653 config :logger,
654 backends: [{ExSyslogger, :ex_syslogger}]
655
656 config :logger, :ex_syslogger,
657 level: :warn
658 ```
659
660 Another example, keeping console output and adding the pid to syslog output:
661 ```elixir
662 config :logger,
663 backends: [:console, {ExSyslogger, :ex_syslogger}]
664
665 config :logger, :ex_syslogger,
666 level: :warn,
667 option: [:pid, :ndelay]
668 ```
669
670 See: [logger’s documentation](https://hexdocs.pm/logger/Logger.html) and [ex_syslogger’s documentation](https://hexdocs.pm/ex_syslogger/)
671
672 An example of logging info to local syslog, but warn to a Slack channel:
673 ```elixir
674 config :logger,
675 backends: [ {ExSyslogger, :ex_syslogger}, Quack.Logger ],
676 level: :info
677
678 config :logger, :ex_syslogger,
679 level: :info,
680 ident: "pleroma",
681 format: "$metadata[$level] $message"
682
683 config :quack,
684 level: :warn,
685 meta: [:all],
686 webhook_url: "https://hooks.slack.com/services/YOUR-API-KEY-HERE"
687 ```
688
689 See the [Quack Github](https://github.com/azohra/quack) for more details
690
691
692
693 ## Database options
694
695 ### RUM indexing for full text search
696
697 !!! warning
698 It is recommended to use PostgreSQL v11 or newer. We have seen some minor issues with lower PostgreSQL versions.
699
700 * `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
701
702 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.
703
704 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.
705
706 To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
707
708 `mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
709
710 This will probably take a long time.
711
712 ## Alternative client protocols
713
714 ### BBS / SSH access
715
716 To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
717
718 ```exs
719 app_dir = File.cwd!
720 priv_dir = Path.join([app_dir, "priv/ssh_keys"])
721
722 config :esshd,
723 enabled: true,
724 priv_dir: priv_dir,
725 handler: "Pleroma.BBS.Handler",
726 port: 10_022,
727 password_authenticator: "Pleroma.BBS.Authenticator"
728 ```
729
730 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`
731
732 ### :gopher
733 * `enabled`: Enables the gopher interface
734 * `ip`: IP address to bind to
735 * `port`: Port to bind to
736 * `dstport`: Port advertised in urls (optional, defaults to `port`)
737
738
739 ## Authentication
740
741 ### :admin_token
742
743 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:
744
745 ```elixir
746 config :pleroma, :admin_token, "somerandomtoken"
747 ```
748
749 You can then do
750
751 ```shell
752 curl "http://localhost:4000/api/pleroma/admin/users/invites?admin_token=somerandomtoken"
753 ```
754
755 or
756
757 ```shell
758 curl -H "X-Admin-Token: somerandomtoken" "http://localhost:4000/api/pleroma/admin/users/invites"
759 ```
760
761 ### :auth
762
763 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
764 * `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
765
766 Authentication / authorization settings.
767
768 * `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`.
769 * `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`.
770 * `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>`).
771
772 ### Pleroma.Web.Auth.Authenticator
773
774 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
775 * `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
776
777 ### :ldap
778
779 Use LDAP for user authentication. When a user logs in to the Pleroma
780 instance, the name and password will be verified by trying to authenticate
781 (bind) to an LDAP server. If a user exists in the LDAP directory but there
782 is no account with the same name yet on the Pleroma instance then a new
783 Pleroma account will be created with the same name as the LDAP user name.
784
785 * `enabled`: enables LDAP authentication
786 * `host`: LDAP server hostname
787 * `port`: LDAP port, e.g. 389 or 636
788 * `ssl`: true to use SSL, usually implies the port 636
789 * `sslopts`: additional SSL options
790 * `tls`: true to start TLS, usually implies the port 389
791 * `tlsopts`: additional TLS options
792 * `base`: LDAP base, e.g. "dc=example,dc=com"
793 * `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
794
795 ### OAuth consumer mode
796
797 OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
798 Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
799
800 !!! note
801 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.
802
803 !!! note
804 Each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
805
806 !!! note
807 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"`
808
809 * For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
810
811 * 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/
812
813 * For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
814
815 * For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
816
817 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`,
818 per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
819
820 ```elixir
821 # Twitter
822 config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
823 consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
824 consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
825
826 # Facebook
827 config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
828 client_id: System.get_env("FACEBOOK_APP_ID"),
829 client_secret: System.get_env("FACEBOOK_APP_SECRET"),
830 redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
831

840 client_id: System.get_env("MICROSOFT_CLIENT_ID"),
841 client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
842
843 config :ueberauth, Ueberauth,
844 providers: [
845 microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
846 ]
847
848 # Keycloak
849 # Note: make sure to add `keycloak:ueberauth_keycloak_strategy` entry to `OAUTH_CONSUMER_STRATEGIES` environment variable
850 keycloak_url = "https://publicly-reachable-keycloak-instance.org:8080"
851
852 config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
853 client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
854 client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),

857 token_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/token",
858 userinfo_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/userinfo",
859 token_method: :post
860
861 config :ueberauth, Ueberauth,
862 providers: [
863 keycloak: {Ueberauth.Strategy.Keycloak, [uid_field: :email]}
864 ]
865 ```
866
867 ### OAuth 2.0 provider - :oauth2
868
869 Configure OAuth 2 provider capabilities:
870
871 * `token_expires_in` - The lifetime in seconds of the access token.
872 * `issue_new_refresh_token` - Keeps old refresh token or generate new refresh token when to obtain an access token.
873 * `clean_expired_tokens` - Enable a background job to clean expired oauth tokens. Defaults to `false`. Interval settings sets in configuration periodic jobs [`Oban.Cron`](#obancron)
874
875 ## Link parsing
876
877 ### :uri_schemes
878 * `valid_schemes`: List of the scheme part that is considered valid to be an URL.
879
880 ### :auto_linker
881
882 Configuration for the `auto_linker` library:
883
884 * `class: "auto-linker"` - specify the class to be added to the generated link. false to clear.
885 * `rel: "noopener noreferrer"` - override the rel attribute. false to clear.
886 * `new_window: true` - set to false to remove `target='_blank'` attribute.
887 * `scheme: false` - Set to true to link urls with schema `http://google.com`.
888 * `truncate: false` - Set to a number to truncate urls longer then the number. Truncated urls will end in `..`.
889 * `strip_prefix: true` - Strip the scheme prefix.
890 * `extra: false` - link urls with rarely used schemes (magnet, ipfs, irc, etc.).
891
892 Example:
893
