Configuration

This page details all the authentik configuration options that you can set via environment variables.

About authentik configurations​

info

The double-underscores are intentional, as all these settings are translated to YAML internally, and a double-underscore indicates the next level (a subsetting).

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://<name> Loads the value from the environment variable <name>. Fallback can be optionally set like env://<name>?<default>
  • file://<name> Loads the value from the file <name>. Fallback can be optionally set like file://<name>?<default>

Set your environment variables​

If you are using Docker Compose, edit your .env file to append any keys that you want to add, and then run the following command to apply them:

docker compose up -d

Verify your configuration 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

authentik Settings​

AUTHENTIK_SECRET_KEY​

Secret key used for cookie signing. Changing this will invalidate active sessions.

caution

Prior to 2023.6.0 the secret key was also used for unique user IDs. When running a pre-2023.6.0 version of authentik the key should not be changed after the first install.

AUTHENTIK_LOG_LEVEL​

Log level for the server and worker containers. Possible values: debug, info, warning, error.

Starting with 2021.12.3, you can also set the log level to trace. This has no effect 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.

Defaults to info.

Which domain the session cookie should be set to. By default, the cookie is set to the domain authentik is accessed under.

AUTHENTIK_EVENTS__CONTEXT_PROCESSORS__GEOIP​

    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.

caution

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