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.

413 ### Pleroma.Web.Plugs.RemoteIp
414
415 !!! warning
416 If your instance is not behind at least one reverse proxy, you should not enable this plug.
417
418 `Pleroma.Web.Plugs.RemoteIp` is a shim to call [`RemoteIp`](https://git.pleroma.social/pleroma/remote_ip) but with runtime configuration.
419
420 Available options:
421
422 * `enabled` - Enable/disable the plug. Defaults to `false`.
423 * `headers` - A list of strings naming the HTTP headers to use when deriving the true client IP address. Defaults to `["x-forwarded-for"]`.
424 * `proxies` - A list of upstream proxy IP subnets in CIDR notation from which we will parse the content of `headers`. Defaults to `[]`. IPv4 entries without a bitmask will be assumed to be /32 and IPv6 /128.
425 * `reserved` - A list of reserved IP subnets in CIDR notation which should be ignored if found in `headers`. Defaults to `["127.0.0.0/8", "::1/128", "fc00::/7", "10.0.0.0/8", "172.16.0.0/12", "192.168.0.0/16"]`.
426
427
428 ### :rate_limit
429
430 !!! note
431 If your instance is behind a reverse proxy ensure [`Pleroma.Web.Plugs.RemoteIp`](#pleroma-plugs-remoteip) is enabled (it is enabled by default).
432
433 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:
434
435 * The first element: `scale` (Integer). The time scale in milliseconds.
436 * The second element: `limit` (Integer). How many requests to limit in the time scale provided.
437
438 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.
439
440 For example:
441
442 ```elixir
443 config :pleroma, :rate_limit,
444 authentication: {60_000, 15},
445 search: [{1000, 10}, {1000, 30}]
446 ```
447
448 Means that:
449
450 1. In 60 seconds, 15 authentication attempts can be performed from the same IP address.
451 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.
452
453 Supported rate limiters:
454
455 * `:search` - Account/Status search.
456 * `:timeline` - Timeline requests (each timeline has it's own limiter).
457 * `:app_account_creation` - Account registration from the API.
458 * `:relations_actions` - Following/Unfollowing in general.
459 * `:relation_id_action` - Following/Unfollowing for a specific user.
460 * `:statuses_actions` - Status actions such as: (un)repeating, (un)favouriting, creating, deleting.
461 * `:status_id_action` - (un)Repeating/(un)Favouriting a particular status.
462 * `:authentication` - Authentication actions, i.e getting an OAuth token.
463 * `:password_reset` - Requesting password reset emails.

470
471 Available caches:
472
473 * `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
474 * `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).
475

507
508 * `:connection_acquisition_wait` - Timeout to acquire a connection from pool.The total max time is this value multiplied by the number of retries.
509 * `connection_acquisition_retries` - Number of attempts to acquire the connection from the pool if it is overloaded. Each attempt is timed `:connection_acquisition_wait` apart.
510 * `:max_connections` - Maximum number of connections in the pool.
511 * `:connect_timeout` - Timeout to connect to the host.
512 * `: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.

523 * `:media` - for rich media, media proxy.
524 * `:upload` - for proxying media when a remote uploader is used and `proxy_remote: true`.
525 * `:default` - for other requests.
526
527 For each pool, the options are:
528
529 * `:size` - limit to how much requests can be concurrently executed.
530 * `:recv_timeout` - timeout while `gun` will wait for response
531 * `:max_waiting` - limit to how much requests can be waiting for others to finish, after this is reached, subsequent requests will be dropped.

603
604 ### Upload filters
605
606 #### Pleroma.Upload.Filter.AnonymizeFilename
607

678 ## Background jobs
679
680 ### Oban
681
682 [Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
683
684 Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
685
686 * `repo` - app's Ecto repo (`Pleroma.Repo`)
687 * `log` - logs verbosity
688 * `queues` - job queues (see below)

706 * `Pleroma.Workers.Cron.NewUsersDigestWorker` - digest emails for admins with new registrations
707
708 ```elixir
709 config :pleroma, Oban,
710 repo: Pleroma.Repo,
711 verbose: false,
712 prune: {:maxlen, 1500},
713 queues: [
714 federator_incoming: 50,
715 federator_outgoing: 50
716 ],
717 crontab: [
718 {"0 0 * * 0", Pleroma.Workers.Cron.DigestEmailsWorker},
719 {"0 0 * * *", Pleroma.Workers.Cron.NewUsersDigestWorker}
720 ]
721 ```
722
723 This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
724
725 #### Migrating `pleroma_job_queue` settings
726
727 `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).
728
729 ### :workers
730
731 Includes custom worker options not interpretable directly by `Oban`.
732
733 * `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
734
735 Example:
736
737 ```elixir
738 config :pleroma, :workers,
739 retries: [
740 federator_incoming: 5,
741 federator_outgoing: 5
742 ]
743 ```
744
745 #### Migrating `Pleroma.Web.Federator.RetryQueue` settings
746
747 * `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
748 * `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
749 * deprecated options: `max_jobs`, `initial_timeout`
750
751 ## :web_push_encryption, :vapid_details
752
753 Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
754
755 * ``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.
756 * ``public_key``: VAPID public key
757 * ``private_key``: VAPID private key
758
759 ## :logger
760 * `backends`: `:console` is used to send logs to stdout, `{ExSyslogger, :ex_syslogger}` to log to syslog, and `Quack.Logger` to log to Slack
761
762 An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
763 ```elixir
764 config :logger,
765 backends: [{ExSyslogger, :ex_syslogger}]
766
767 config :logger, :ex_syslogger,
768 level: :warn
769 ```
770
771 Another example, keeping console output and adding the pid to syslog output:
772 ```elixir
773 config :logger,
774 backends: [:console, {ExSyslogger, :ex_syslogger}]
775
776 config :logger, :ex_syslogger,
777 level: :warn,
778 option: [:pid, :ndelay]
779 ```
780
781 See: [logger’s documentation](https://hexdocs.pm/logger/Logger.html) and [ex_syslogger’s documentation](https://hexdocs.pm/ex_syslogger/)
782
783 An example of logging info to local syslog, but warn to a Slack channel:
784 ```elixir
785 config :logger,
786 backends: [ {ExSyslogger, :ex_syslogger}, Quack.Logger ],
787 level: :info
788
789 config :logger, :ex_syslogger,
790 level: :info,
791 ident: "pleroma",
792 format: "$metadata[$level] $message"
793
794 config :quack,
795 level: :warn,
796 meta: [:all],
797 webhook_url: "https://hooks.slack.com/services/YOUR-API-KEY-HERE"
798 ```
799

803
804 ## Database options
805
806 ### RUM indexing for full text search
807
808 !!! warning
809 It is recommended to use PostgreSQL v11 or newer. We have seen some minor issues with lower PostgreSQL versions.
810
811 * `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
812
813 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.
814
815 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.
816
817 To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
818
819 `mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
820
821 This will probably take a long time.
822
823 ## Alternative client protocols
824
825 ### BBS / SSH access
826
827 To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
828
829 ```exs
830 app_dir = File.cwd!
831 priv_dir = Path.join([app_dir, "priv/ssh_keys"])
832
833 config :esshd,
834 enabled: true,
835 priv_dir: priv_dir,
836 handler: "Pleroma.BBS.Handler",
837 port: 10_022,
838 password_authenticator: "Pleroma.BBS.Authenticator"
839 ```
840
841 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`
842
843 ### :gopher
844 * `enabled`: Enables the gopher interface
845 * `ip`: IP address to bind to
846 * `port`: Port to bind to
847 * `dstport`: Port advertised in urls (optional, defaults to `port`)
848
849
850 ## Authentication
851
852 ### :admin_token
853
854 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:
855
856 ```elixir
857 config :pleroma, :admin_token, "somerandomtoken"
858 ```
859
860 You can then do
861
862 ```shell
863 curl "http://localhost:4000/api/pleroma/admin/users/invites?admin_token=somerandomtoken"
864 ```
865
866 or
867
868 ```shell
869 curl -H "X-Admin-Token: somerandomtoken" "http://localhost:4000/api/pleroma/admin/users/invites"
870 ```
871
872 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.
873
874 ### :auth
875
876 Authentication / authorization settings.
877
878 * `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`.
879 * `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`.
880 * `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>`).
881
882 ### Pleroma.Web.Auth.Authenticator
883
884 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
885 * `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
886
887 ### :ldap
888
889 Use LDAP for user authentication. When a user logs in to the Pleroma
890 instance, the name and password will be verified by trying to authenticate
891 (bind) to an LDAP server. If a user exists in the LDAP directory but there
892 is no account with the same name yet on the Pleroma instance then a new
893 Pleroma account will be created with the same name as the LDAP user name.
894
895 * `enabled`: enables LDAP authentication
896 * `host`: LDAP server hostname
897 * `port`: LDAP port, e.g. 389 or 636
898 * `ssl`: true to use SSL, usually implies the port 636
899 * `sslopts`: additional SSL options
900 * `tls`: true to start TLS, usually implies the port 389
901 * `tlsopts`: additional TLS options
902 * `base`: LDAP base, e.g. "dc=example,dc=com"
903 * `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
904
905 Note, if your LDAP server is an Active Directory server the correct value is commonly `uid: "cn"`, but if you use an
906 OpenLDAP server the value may be `uid: "uid"`.
907
908 ### OAuth consumer mode
909
910 OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
911 Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
912
913 !!! note
914 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.
915
916 !!! note
917 Each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
918
919 !!! note
920 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"`
921
922 * For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
923
924 * 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/
925
926 * For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
927
928 * For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
929
930 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`,
931 per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
932
933 ```elixir
934 # Twitter
935 config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
936 consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
937 consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
938
939 # Facebook
940 config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
941 client_id: System.get_env("FACEBOOK_APP_ID"),
942 client_secret: System.get_env("FACEBOOK_APP_SECRET"),
943 redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
944
945 # Google
946 config :ueberauth, Ueberauth.Strategy.Google.OAuth,
947 client_id: System.get_env("GOOGLE_CLIENT_ID"),
948 client_secret: System.get_env("GOOGLE_CLIENT_SECRET"),
949 redirect_uri: System.get_env("GOOGLE_REDIRECT_URI")
950
951 # Microsoft
952 config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
953 client_id: System.get_env("MICROSOFT_CLIENT_ID"),
954 client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
955
956 config :ueberauth, Ueberauth,
957 providers: [
958 microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
959 ]
960
961 # Keycloak
962 # Note: make sure to add `keycloak:ueberauth_keycloak_strategy` entry to `OAUTH_CONSUMER_STRATEGIES` environment variable
963 keycloak_url = "https://publicly-reachable-keycloak-instance.org:8080"
964
965 config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
966 client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
967 client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),
968 site: keycloak_url,
969 authorize_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/auth",
970 token_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/token",
971 userinfo_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/userinfo",
972 token_method: :post
973
974 config :ueberauth, Ueberauth,
975 providers: [
976 keycloak: {Ueberauth.Strategy.Keycloak, [uid_field: :email]}
977 ]
978 ```
979
980 ### OAuth 2.0 provider - :oauth2
981
982 Configure OAuth 2 provider capabilities:
983
984 * `token_expires_in` - The lifetime in seconds of the access token.
985 * `issue_new_refresh_token` - Keeps old refresh token or generate new refresh token when to obtain an access token.
986 * `clean_expired_tokens` - Enable a background job to clean expired oauth tokens. Defaults to `false`.
987
988 ## Link parsing
989
990 ### :uri_schemes
991 * `valid_schemes`: List of the scheme part that is considered valid to be an URL.
992
993 ### Pleroma.Formatter
994
995 Configuration for Pleroma's link formatter which parses mentions, hashtags, and URLs.
996
997 * `class` - specify the class to be added to the generated link (default: `false`)
998 * `rel` - specify the rel attribute (default: `ugc`)
999 * `new_window` - adds `target="_blank"` attribute (default: `false`)
1000 * `truncate` - Set to a number to truncate URLs longer then the number. Truncated URLs will end in `...` (default: `false`)
1001 * `strip_prefix` - Strip the scheme prefix (default: `false`)
1002 * `extra` - link URLs with rarely used schemes (magnet, ipfs, irc, etc.) (default: `true`)
1003 * `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`)
1004
1005 Example:
1006
1007 ```elixir
1008 config :pleroma, Pleroma.Formatter,
1009 class: false,
1010 rel: "ugc",
1011 new_window: false,
1012 truncate: false,
1013 strip_prefix: false,
1014 extra: true,
1015 validate_tld: :no_scheme
1016 ```
1017
1018 ## Custom Runtime Modules (`:modules`)
1019
1020 * `runtime_dir`: A path to custom Elixir modules (such as MRF policies).
1021
1022 ## :configurable_from_database
1023
1024 Boolean, enables/disables in-database configuration. Read [Transfering the config to/from the database](../administration/CLI_tasks/config.md) for more information.
1025
1026 ## :database_config_whitelist
1027
1028 List of valid configuration sections which are allowed to be configured from the
1029 database. Settings stored in the database before the whitelist is configured are
1030 still applied, so it is suggested to only use the whitelist on instances that
1031 have not migrated the config to the database.
1032
1033 Example:
1034 ```elixir
1035 config :pleroma, :database_config_whitelist, [
1036 {:pleroma, :instance},
1037 {:pleroma, Pleroma.Web.Metadata},
1038 {:auto_linker}
1039 ]
1040 ```
1041
1042 ### Multi-factor authentication - :two_factor_authentication
1043 * `totp` - a list containing TOTP configuration
1044 - `digits` - Determines the length of a one-time pass-code in characters. Defaults to 6 characters.
1045 - `period` - a period for which the TOTP code will be valid in seconds. Defaults to 30 seconds.
1046 * `backup_codes` - a list containing backup codes configuration
1047 - `number` - number of backup codes to generate.
1048 - `length` - backup code length. Defaults to 16 characters.
1049
1050 ## Restrict entities access for unauthenticated users
1051
1052 ### :restrict_unauthenticated
1053
1054 Restrict access for unauthenticated users to timelines (public and federated), user profiles and statuses.
1055
1056 * `timelines`: public and federated timelines
1057 * `local`: public timeline
1058 * `federated`: federated timeline (includes public timeline)
1059 * `profiles`: user profiles
1060 * `local`
1061 * `remote`
1062 * `activities`: statuses
1063 * `local`
1064 * `remote`
1065
1066 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`.
1067
1068 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).
1069
1070 ## Pleroma.Web.ApiSpec.CastAndValidate
1071
1072 * `:strict` a boolean, enables strict input validation (useful in development, not recommended in production). Defaults to `false`.
1073
1074 ## :instances_favicons
1075
1076 Control favicons for instances.
1077
1078 * `enabled`: Allow/disallow displaying and getting instances favicons
1079
1080 ## Account Backup
1081
1082 !!! note
1083 Requires enabled email
1084
1085 * `:purge_after_days` an integer, remove backup achives after N days.
1086 * `:limit_days` an integer, limit user to export not more often than once per N days.
1087 * `:dir` a string with a path to backup temporary directory or `nil` to let Pleroma choose temporary directory in the following order:
1088 1. the directory named by the TMPDIR environment variable
1089 2. the directory named by the TEMP environment variable
1090 3. the directory named by the TMP environment variable
1091 4. C:\TMP on Windows or /tmp on Unix-like operating systems
1092 5. as a last resort, the current working directory
1093
1094 ## Frontend management
1095
1096 Frontends in Pleroma are swappable - you can specify which one to use here.
1097
1098 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.
1099
1100 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.
1101
1102 If you don't set anything here, the bundled frontends will be used.
1103
1104 Example:
1105
1106 ```
1107 config :pleroma, :frontends,
1108 primary: %{
1109 "name" => "pleroma",
1110 "ref" => "stable"
1111 },
1112 admin: %{
1113 "name" => "admin",
1114 "ref" => "develop"
1115 }
1116 ```
1117
1118 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.
1119
1120 ## Ephemeral activities (Pleroma.Workers.PurgeExpiredActivity)
1121
1122 Settings to enable and configure expiration for ephemeral activities
1123
1124 * `:enabled` - enables ephemeral activities creation
1125 * `:min_lifetime` - minimum lifetime for ephemeral activities (in seconds). Default: 10 minutes.
