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.

405 * `extra_cookie_attrs` - a list of `Key=Value` strings to be added as non-standard cookie attributes. Defaults to `["SameSite=Lax"]`. See the [SameSite article](https://www.owasp.org/index.php/SameSite) on OWASP for more info.
406
407 Example:
408 ```elixir
409 config :pleroma, Pleroma.Web.Endpoint,
410 url: [host: "example.com", port: 2020, scheme: "https"],
411 http: [
412 port: 8080,
413 ip: {127, 0, 0, 1}
414 ]
415 ```
416
417 This will make Pleroma listen on `127.0.0.1` port `8080` and generate urls starting with `https://example.com:2020`
418
419 ### :http_security
420 * ``enabled``: Whether the managed content security policy is enabled.

427 ### Pleroma.Web.Plugs.RemoteIp
428
429 !!! warning
430 If your instance is not behind at least one reverse proxy, you should not enable this plug.
431
432 `Pleroma.Web.Plugs.RemoteIp` is a shim to call [`RemoteIp`](https://git.pleroma.social/pleroma/remote_ip) but with runtime configuration.
433
434 Available options:
435
436 * `enabled` - Enable/disable the plug. Defaults to `false`.
437 * `headers` - A list of strings naming the HTTP headers to use when deriving the true client IP address. Defaults to `["x-forwarded-for"]`.
438 * `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.
439 * `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"]`.
440
441
442 ### :rate_limit
443
444 !!! note
445 If your instance is behind a reverse proxy ensure [`Pleroma.Web.Plugs.RemoteIp`](#pleroma-plugs-remoteip) is enabled (it is enabled by default).
446
447 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:
448
449 * The first element: `scale` (Integer). The time scale in milliseconds.
450 * The second element: `limit` (Integer). How many requests to limit in the time scale provided.
451
452 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.
453
454 For example:
455
456 ```elixir
457 config :pleroma, :rate_limit,
458 authentication: {60_000, 15},
459 search: [{1000, 10}, {1000, 30}]
460 ```
461
462 Means that:
463
464 1. In 60 seconds, 15 authentication attempts can be performed from the same IP address.
465 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.
466
467 Supported rate limiters:
468
469 * `:search` - Account/Status search.
470 * `:timeline` - Timeline requests (each timeline has it's own limiter).
471 * `:app_account_creation` - Account registration from the API.

484
485 Available caches:
486
487 * `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
488 * `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).

531
532 Settings for request pools. These pools are limited on top of `:connections_pool`.
533
534 There are four pools used:
535

537 * `:media` - for rich media, media proxy.
538 * `:upload` - for proxying media when a remote uploader is used and `proxy_remote: true`.
539 * `:default` - for other requests.
540
541 For each pool, the options are:
542
543 * `:size` - limit to how much requests can be concurrently executed.
544 * `:recv_timeout` - timeout while `gun` will wait for response

614
615 ### Upload filters
616
617 #### Pleroma.Upload.Filter.AnonymizeFilename
618
619 This filter replaces the filename (not the path) of an upload. For complete obfuscation, add
620 `Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.

689 ## Background jobs
690
691 ### Oban
692
693 [Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
694
695 Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
696
697 * `repo` - app's Ecto repo (`Pleroma.Repo`)
698 * `log` - logs verbosity
699 * `queues` - job queues (see below)
700 * `crontab` - periodic jobs, see [`Oban.Cron`](#obancron)
701
702 Pleroma has the following queues:
703
704 * `activity_expiration` - Activity expiration
705 * `federator_outgoing` - Outgoing federation
706 * `federator_incoming` - Incoming federation
707 * `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
708 * `transmogrifier` - Transmogrifier
709 * `web_push` - Web push notifications
710 * `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
711
712 #### Oban.Cron
713
714 Pleroma has these periodic job workers:
715
716 * `Pleroma.Workers.Cron.DigestEmailsWorker` - digest emails for users with new mentions and follows
717 * `Pleroma.Workers.Cron.NewUsersDigestWorker` - digest emails for admins with new registrations
718
719 ```elixir
720 config :pleroma, Oban,
721 repo: Pleroma.Repo,
722 verbose: false,
723 prune: {:maxlen, 1500},
724 queues: [
725 federator_incoming: 50,
726 federator_outgoing: 50
727 ],
728 crontab: [
729 {"0 0 * * 0", Pleroma.Workers.Cron.DigestEmailsWorker},
730 {"0 0 * * *", Pleroma.Workers.Cron.NewUsersDigestWorker}
731 ]
732 ```
733
734 This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
735
736 #### Migrating `pleroma_job_queue` settings
737
738 `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).
739
740 ### :workers
741
742 Includes custom worker options not interpretable directly by `Oban`.
743
744 * `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
745
746 Example:
747
748 ```elixir
749 config :pleroma, :workers,
750 retries: [
751 federator_incoming: 5,
752 federator_outgoing: 5
753 ]
754 ```
755
756 #### Migrating `Pleroma.Web.Federator.RetryQueue` settings
757
758 * `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
759 * `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
760 * deprecated options: `max_jobs`, `initial_timeout`
761
762 ## :web_push_encryption, :vapid_details
763
764 Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
765
766 * ``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.
767 * ``public_key``: VAPID public key
768 * ``private_key``: VAPID private key
769
770 ## :logger
771 * `backends`: `:console` is used to send logs to stdout, `{ExSyslogger, :ex_syslogger}` to log to syslog, and `Quack.Logger` to log to Slack
772
773 An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
774 ```elixir
775 config :logger,
776 backends: [{ExSyslogger, :ex_syslogger}]
777
778 config :logger, :ex_syslogger,
779 level: :warn
780 ```
781
782 Another example, keeping console output and adding the pid to syslog output:
783 ```elixir
784 config :logger,
785 backends: [:console, {ExSyslogger, :ex_syslogger}]
786
787 config :logger, :ex_syslogger,
788 level: :warn,
789 option: [:pid, :ndelay]
790 ```
791
792 See: [logger’s documentation](https://hexdocs.pm/logger/Logger.html) and [ex_syslogger’s documentation](https://hexdocs.pm/ex_syslogger/)
793
794 An example of logging info to local syslog, but warn to a Slack channel:
795 ```elixir
796 config :logger,
797 backends: [ {ExSyslogger, :ex_syslogger}, Quack.Logger ],
798 level: :info
799
800 config :logger, :ex_syslogger,
801 level: :info,
802 ident: "pleroma",
803 format: "$metadata[$level] $message"
804
805 config :quack,
806 level: :warn,
807 meta: [:all],
808 webhook_url: "https://hooks.slack.com/services/YOUR-API-KEY-HERE"
809 ```
810
811 See the [Quack Github](https://github.com/azohra/quack) for more details
812
813
814
815 ## Database options
816
817 ### RUM indexing for full text search
818
819 !!! warning
820 It is recommended to use PostgreSQL v11 or newer. We have seen some minor issues with lower PostgreSQL versions.
821
822 * `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
823
824 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.
825
826 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.
827
828 To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
829
830 `mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
831
832 This will probably take a long time.
833
834 ## Alternative client protocols
835
836 ### BBS / SSH access
837
838 To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
839
840 ```exs
841 app_dir = File.cwd!
842 priv_dir = Path.join([app_dir, "priv/ssh_keys"])
843
844 config :esshd,
845 enabled: true,
846 priv_dir: priv_dir,
847 handler: "Pleroma.BBS.Handler",
848 port: 10_022,
849 password_authenticator: "Pleroma.BBS.Authenticator"
850 ```
851
852 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`
853
854 ### :gopher
855 * `enabled`: Enables the gopher interface
856 * `ip`: IP address to bind to
857 * `port`: Port to bind to
858 * `dstport`: Port advertised in urls (optional, defaults to `port`)
859
860
861 ## Authentication
862
863 ### :admin_token
864
865 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:
866
867 ```elixir
868 config :pleroma, :admin_token, "somerandomtoken"
869 ```
870
871 You can then do
872
873 ```shell
874 curl "http://localhost:4000/api/v1/pleroma/admin/users/invites?admin_token=somerandomtoken"
875 ```
876
877 or
878
879 ```shell
880 curl -H "X-Admin-Token: somerandomtoken" "http://localhost:4000/api/v1/pleroma/admin/users/invites"
881 ```
882
883 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.
884
885 ### :auth
886
887 Authentication / authorization settings.
888
889 * `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`.
890 * `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`.
891 * `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>`).
892
893 ### Pleroma.Web.Auth.Authenticator
894
895 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
896 * `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
897
898 ### :ldap
899
900 Use LDAP for user authentication. When a user logs in to the Pleroma
901 instance, the name and password will be verified by trying to authenticate
902 (bind) to an LDAP server. If a user exists in the LDAP directory but there
903 is no account with the same name yet on the Pleroma instance then a new
904 Pleroma account will be created with the same name as the LDAP user name.
905
906 * `enabled`: enables LDAP authentication
907 * `host`: LDAP server hostname
908 * `port`: LDAP port, e.g. 389 or 636
909 * `ssl`: true to use SSL, usually implies the port 636
910 * `sslopts`: additional SSL options
911 * `tls`: true to start TLS, usually implies the port 389
912 * `tlsopts`: additional TLS options
913 * `base`: LDAP base, e.g. "dc=example,dc=com"
914 * `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
915
916 Note, if your LDAP server is an Active Directory server the correct value is commonly `uid: "cn"`, but if you use an
917 OpenLDAP server the value may be `uid: "uid"`.
918
919 ### :oauth2 (Pleroma as OAuth 2.0 provider settings)
920
921 OAuth 2.0 provider settings:
922
923 * `token_expires_in` - The lifetime in seconds of the access token.
924 * `issue_new_refresh_token` - Keeps old refresh token or generate new refresh token when to obtain an access token.
925 * `clean_expired_tokens` - Enable a background job to clean expired oauth tokens. Defaults to `false`.
926
927 OAuth 2.0 provider and related endpoints:
928
929 * `POST /api/v1/apps` creates client app basing on provided params.
930 * `GET/POST /oauth/authorize` renders/submits authorization form.
931 * `POST /oauth/token` creates/renews OAuth token.
932 * `POST /oauth/revoke` revokes provided OAuth token.
933 * `GET /api/v1/accounts/verify_credentials` (with proper `Authorization` header or `access_token` URI param) returns user info on requester (with `acct` field containing local nickname and `fqn` field containing fully-qualified nickname which could generally be used as email stub for OAuth software that demands email field in identity endpoint response, like Peertube).
934
935 ### OAuth consumer mode
936
937 OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
938 Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
939
940 !!! note
941 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.
942
943 !!! note
944 Each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
945
946 !!! note
947 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"`
948
949 * For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
950
951 * 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/
952
953 * For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
954
955 * For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
956
957 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`,
958 per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
959
960 ```elixir
961 # Twitter
962 config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
963 consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
964 consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
965
966 # Facebook
967 config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
968 client_id: System.get_env("FACEBOOK_APP_ID"),
969 client_secret: System.get_env("FACEBOOK_APP_SECRET"),
970 redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
971
972 # Google
973 config :ueberauth, Ueberauth.Strategy.Google.OAuth,
974 client_id: System.get_env("GOOGLE_CLIENT_ID"),
975 client_secret: System.get_env("GOOGLE_CLIENT_SECRET"),
976 redirect_uri: System.get_env("GOOGLE_REDIRECT_URI")
977
978 # Microsoft
979 config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
980 client_id: System.get_env("MICROSOFT_CLIENT_ID"),
981 client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
982
983 config :ueberauth, Ueberauth,
984 providers: [
985 microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
986 ]
987
988 # Keycloak
989 # Note: make sure to add `keycloak:ueberauth_keycloak_strategy` entry to `OAUTH_CONSUMER_STRATEGIES` environment variable
990 keycloak_url = "https://publicly-reachable-keycloak-instance.org:8080"
991
992 config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
993 client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
994 client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),
995 site: keycloak_url,
996 authorize_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/auth",
997 token_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/token",
998 userinfo_url: "#{keycloak_url}/auth/realms/master/protocol/openid-connect/userinfo",
999 token_method: :post
1000
1001 config :ueberauth, Ueberauth,
1002 providers: [
1003 keycloak: {Ueberauth.Strategy.Keycloak, [uid_field: :email]}
1004 ]
1005 ```
1006
1007 ## Link parsing
1008
1009 ### :uri_schemes
1010 * `valid_schemes`: List of the scheme part that is considered valid to be an URL.
1011
1012 ### Pleroma.Formatter
1013
1014 Configuration for Pleroma's link formatter which parses mentions, hashtags, and URLs.
1015
1016 * `class` - specify the class to be added to the generated link (default: `false`)
1017 * `rel` - specify the rel attribute (default: `ugc`)
1018 * `new_window` - adds `target="_blank"` attribute (default: `false`)
1019 * `truncate` - Set to a number to truncate URLs longer then the number. Truncated URLs will end in `...` (default: `false`)
1020 * `strip_prefix` - Strip the scheme prefix (default: `false`)
1021 * `extra` - link URLs with rarely used schemes (magnet, ipfs, irc, etc.) (default: `true`)
1022 * `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`)
1023
1024 Example:
1025
1026 ```elixir
1027 config :pleroma, Pleroma.Formatter,
1028 class: false,
1029 rel: "ugc",
1030 new_window: false,
1031 truncate: false,
1032 strip_prefix: false,
1033 extra: true,
1034 validate_tld: :no_scheme
1035 ```
1036
1037 ## Custom Runtime Modules (`:modules`)
1038
1039 * `runtime_dir`: A path to custom Elixir modules (such as MRF policies).
1040
1041 ## :configurable_from_database
1042
1043 Boolean, enables/disables in-database configuration. Read [Transfering the config to/from the database](../administration/CLI_tasks/config.md) for more information.
1044
1045 ## :database_config_whitelist
1046
1047 List of valid configuration sections which are allowed to be configured from the
1048 database. Settings stored in the database before the whitelist is configured are
1049 still applied, so it is suggested to only use the whitelist on instances that
1050 have not migrated the config to the database.
1051
1052 Example:
1053 ```elixir
1054 config :pleroma, :database_config_whitelist, [
1055 {:pleroma, :instance},
1056 {:pleroma, Pleroma.Web.Metadata},
1057 {:auto_linker}
1058 ]
1059 ```
1060
1061 ### Multi-factor authentication - :two_factor_authentication
1062 * `totp` - a list containing TOTP configuration
1063 - `digits` - Determines the length of a one-time pass-code in characters. Defaults to 6 characters.
1064 - `period` - a period for which the TOTP code will be valid in seconds. Defaults to 30 seconds.
1065 * `backup_codes` - a list containing backup codes configuration
1066 - `number` - number of backup codes to generate.
1067 - `length` - backup code length. Defaults to 16 characters.
1068
1069 ## Restrict entities access for unauthenticated users
1070
1071 ### :restrict_unauthenticated
1072
1073 Restrict access for unauthenticated users to timelines (public and federated), user profiles and statuses.
1074
1075 * `timelines`: public and federated timelines
1076 * `local`: public timeline
1077 * `federated`: federated timeline (includes public timeline)
1078 * `profiles`: user profiles
1079 * `local`
1080 * `remote`
1081 * `activities`: statuses
1082 * `local`
1083 * `remote`
1084
1085 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`.
1086
1087 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).
1088
1089 ## Pleroma.Web.ApiSpec.CastAndValidate
1090
1091 * `:strict` a boolean, enables strict input validation (useful in development, not recommended in production). Defaults to `false`.
1092
1093 ## :instances_favicons
1094
1095 Control favicons for instances.
1096
1097 * `enabled`: Allow/disallow displaying and getting instances favicons
1098
1099 ## Pleroma.User.Backup
1100
1101 !!! note
1102 Requires enabled email
1103
1104 * `:purge_after_days` an integer, remove backup achives after N days.
1105 * `:limit_days` an integer, limit user to export not more often than once per N days.
1106 * `:dir` a string with a path to backup temporary directory or `nil` to let Pleroma choose temporary directory in the following order:
1107 1. the directory named by the TMPDIR environment variable
1108 2. the directory named by the TEMP environment variable
1109 3. the directory named by the TMP environment variable
1110 4. C:\TMP on Windows or /tmp on Unix-like operating systems
1111 5. as a last resort, the current working directory
1112
1113 ## Frontend management
1114
1115 Frontends in Pleroma are swappable - you can specify which one to use here.
1116
1117 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.
1118
1119 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.
1120
1121 If you don't set anything here, the bundled frontends will be used.
1122
1123 Example:
1124
1125 ```
1126 config :pleroma, :frontends,
1127 primary: %{
1128 "name" => "pleroma",
1129 "ref" => "stable"
1130 },
1131 admin: %{
1132 "name" => "admin",
1133 "ref" => "develop"
1134 }
1135 ```
1136
1137 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.
1138
1139 ## Ephemeral activities (Pleroma.Workers.PurgeExpiredActivity)
1140
1141 Settings to enable and configure expiration for ephemeral activities
1142
1143 * `:enabled` - enables ephemeral activities creation
1144 * `:min_lifetime` - minimum lifetime for ephemeral activities (in seconds). Default: 10 minutes.
1145
1146 ## ConcurrentLimiter
1147
1148 Settings to restrict concurrently running jobs. Jobs which can be configured:
1149
1150 * `Pleroma.Web.RichMedia.Helpers` - generating link previews of URLs in activities
1151 * `Pleroma.Web.ActivityPub.MRF.MediaProxyWarmingPolicy` - warming remote media cache via MediaProxyWarmingPolicy
1152
1153 Each job has these settings:
1154
1155 * `:max_running` - max concurrently runnings jobs
1156 * `:max_waiting` - max waiting jobs
