Configuration
This file describe the configuration, it is recommended to edit the relevant *.secret.exs file instead of the others founds in the config
directory.
If you run Pleroma with MIX_ENV=prod
the file is prod.secret.exs
, otherwise it is dev.secret.exs
.
Pleroma.Upload

: When enabled Pleroma will add aname
parameter to the url of the upload, for examplehttps://instance.tld/media/corndog.png?name=corndog.png
. This is needed to provide the correct filename in Content-Disposition headers when using filters likePleroma.Upload.Filter.Dedupe
base_url
: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.proxy_remote

:frontend_configurations
This can be used to configure a keyword list that keeps the configuration data for any kind of frontend. By default, settings for pleroma_fe
and masto_fe
are configured.
Frontends can access these settings at /api/pleroma/frontend_configurations
To add your own configuration for PleromaFE, use it like this:
config :pleroma, :frontend_configurations,
pleroma_fe: %{
theme: "pleroma-dark",
# ... see /priv/static/static/config.json for the available keys.
},
masto_fe: %{
showInstanceSpecificPanel: true
}
These settings need to be complete, they will override the defaults.
NOTE: for versions < 1.0, you need to set :fe
to false, as shown a few lines below.
:fe
THIS IS DEPRECATED
If you are using this method, please change it to the frontend_configurations
method.
Please set this option to false in your config like this:

Pleroma.Web.Auth.Authenticator
Pleroma.Web.Auth.PleromaAuthenticator
: default database authenticatorPleroma.Web.Auth.LDAPAuthenticator
: LDAP authentication
:ldap
Use LDAP for user authentication. When a user logs in to the Pleroma instance, the name and password will be verified by trying to authenticate (bind) to an LDAP server. If a user exists in the LDAP directory but there is no account with the same name yet on the Pleroma instance then a new Pleroma account will be created with the same name as the LDAP user name.
enabled
: enables LDAP authenticationhost
: LDAP server hostnameport
: LDAP port, e.g. 389 or 636ssl
: true to use SSL, usually implies the port 636sslopts
: additional SSL optionstls
: true to start TLS, usually implies the port 389tlsopts
: additional TLS optionsbase
: LDAP base, e.g. "dc=example,dc=com"uid
: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
BBS / SSH access
To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
app_dir = File.cwd!
priv_dir = Path.join([app_dir, "priv/ssh_keys"])
config :esshd,
enabled: true,
priv_dir: priv_dir,
handler: "Pleroma.BBS.Handler",
port: 10_022,
password_authenticator: "Pleroma.BBS.Authenticator"
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
:auth
Pleroma.Web.Auth.PleromaAuthenticator
: default database authenticatorPleroma.Web.Auth.LDAPAuthenticator
: LDAP authentication
Authentication / authorization settings.
auth_template
: authentication form template. By default it'sshow.html
which corresponds tolib/pleroma/web/templates/o_auth/o_auth/show.html.eex
.oauth_consumer_template
: OAuth consumer mode authentication form template. By default it'sconsumer.html
which corresponds tolib/pleroma/web/templates/o_auth/o_auth/consumer.html.eex
.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
orkeycloak:ueberauth_keycloak_strategy
in case dependency is named differently thanueberauth_<strategy>
).
OAuth consumer mode
OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.). Implementation is based on Ueberauth; see the list of available strategies.
Note: 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.
Note: each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
Note: 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"
-
For Twitter, register an app, configure callback URL to https://<your_host>/oauth/twitter/callback
-
For Facebook, register an app, 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/
-
For Google, register an app, configure callback URL to https://<your_host>/oauth/google/callback
-
For Microsoft, register an app, configure callback URL to https://<your_host>/oauth/microsoft/callback
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
,
per strategy's documentation (e.g. ueberauth_twitter). Example config basing on environment variables:
# Twitter
config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")
# Facebook
config :ueberauth, Ueberauth.Strategy.Facebook.OAuth,
client_id: System.get_env("FACEBOOK_APP_ID"),
client_secret: System.get_env("FACEBOOK_APP_SECRET"),
redirect_uri: System.get_env("FACEBOOK_REDIRECT_URI")
# Google
config :ueberauth, Ueberauth.Strategy.Google.OAuth,
client_id: System.get_env("GOOGLE_CLIENT_ID"),
client_secret: System.get_env("GOOGLE_CLIENT_SECRET"),
redirect_uri: System.get_env("GOOGLE_REDIRECT_URI")
# Microsoft
config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
client_id: System.get_env("MICROSOFT_CLIENT_ID"),
client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
config :ueberauth, Ueberauth,
providers: [
microsoft: {Ueberauth.Strategy.Microsoft, [callback_params: []]}
]
OAuth 2.0 provider - :oauth2

token_expires_in
- The lifetime in seconds of the access token.issue_new_refresh_token
- Keeps old refresh token or generate new refresh token when to obtain an access token.clean_expired_tokens
- Enable a background job to clean expired oauth tokens. Defaults tofalse
.clean_expired_tokens_interval
- Interval to run the job to clean expired tokens. Defaults to86_400_000
(24 hours).
:emoji
shortcode_globs
: Location of custom emoji files.*
can be used as a wildcard. Example["/emoji/custom/**/*.png"]
groups
: Emojis are ordered in groups (tags). This is an array of key-value pairs where the key is the groupname and the value the location or array of locations.*
can be used as a wildcard. Example[Custom: ["/emoji/*.png", "/emoji/custom/*.png"]]
default_manifest
: Location of the JSON-manifest. This manifest contains information about the emoji-packs you can download. Currently only one manifest can be added (no arrays).
Database options
RUM indexing for full text search
rum_enabled
: If RUM indexes should be used. Defaults tofalse
.
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.
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.
To enable them, both the rum_enabled
flag has to be set and the following special migration has to be run:
mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/
This will probably take a long time.
