# Configuration These are all the configuration options you can set via environment variables. Append any of the following keys to your `.env` file, and run `docker-compose up -d` to apply them.

**Info** The double-underscores are intentional, as all these settings are translated to yaml internally, a double-underscore indicates the next level.

All of these variables can be set to values, but you can also use a URI-like format to load values from other places: - `env://` Loads the value from the environment variable ``. Fallback can be optionally set like `env://?` - `file://` Loads the value from the file ``. Fallback can be optionally set like `file://?` ## Checking settings[​](https://goauthentik.io/docs/installation/configuration#checking-settings "Direct link to Checking settings") To check if your config has been applied correctly, you can run the following command to output the full config: ``` docker-compose run --rm worker dump_config # Or for kubernetes kubectl exec -it deployment/authentik-worker -c authentik -- ak dump_config ```

This has no affect on the core authentik server, but shows additional messages for the embedded outpost.

DANGER Setting the log level to `trace` will include sensitive details in logs, so it shouldn't be used in most cases. Logs generated with `trace` should be treated with care as they can give others access to your instance, and can potentially include things like session cookies to authentik **and other pages**.

Anonymous performance data is also sent. - `AUTHENTIK_ERROR_REPORTING__SENTRY_DSN` Sets the DSN for the Sentry API endpoint. When error reporting is enabled, the default Sentry DSN will allow the authentik developers to receive error reports and anonymous performance data, which is used for general feedback about authentik, and in some cases, may be used for debugging purposes. Users can create their own hosted Sentry account (or self-host Sentry) and opt to collect this data themselves. - `AUTHENTIK_ERROR_REPORTING__ENVIRONMENT` The environment tag associated with all data sent to Sentry. Defaults to `customer`. When error reporting has been enabled to aid in debugging issues, this should be set to a unique value, such as an e-mail address. - `AUTHENTIK_ERROR_REPORTING__SEND_PII` Whether or not to send personal data, like usernames.

Default: `ghcr.io/goauthentik/%(type)s:%(version)s`. - `AUTHENTIK_OUTPOSTS__DISCOVER` Configure the automatic discovery of integrations. Defaults to `true`. By default, the following is discovered: - Kubernetes in-cluster config - Kubeconfig - Existence of a docker socket ### `AUTHENTIK_AVATARS`[​](https://goauthentik.io/docs/installation/configuration#authentik_avatars "Direct link to authentik_avatars") Configure how authentik should show avatars for users. Following values can be set: Default: `gravatar,initials` - `none`: Disables per-user avatars and just shows a 1x1 pixel transparent picture - `gravatar`: Uses gravatar with the user's email address - `initials`: Generated avatars based on the user's name - Any URL: If you want to use images hosted on another server, you can set any URL. Additionally, these placeholders can be used: - `%(username)s`: The user's username - `%(mail_hash)s`: The email address, md5 hashed - `%(upn)s`: The user's UPN, if set (otherwise an empty string) Starting with authentik 2022.8, you can also use an attribute path like `attributes.something.avatar`, which can be used in combination with the file field to allow users to upload custom avatars for themselves. Starting with authentik 2023.2, multiple modes can be set, and authentik will fallback to the next mode when no avatar could be found. For example, setting this to `gravatar,initials` will attempt to get an avatar from Gravatar, and if the user has not configured on there, it will fallback to a generated avatar. `AUTHENTIK_DEFAULT_USER_CHANGE_NAME`[​](https://goauthentik.io/docs/installation/configuration#authentik_default_user_change_name "Direct link to authentik_default_user_change_name")

CAUTION Using these custom settings is not supported and can prevent your authentik instance from starting. Use with caution.
