Environment	Using the Environment Variable Configuration Method.	Authelia has a layered configuration model. This section describes how to implement the environment configuration.	2022-06-15T17:51:47+10:00	false		configuration parent methods	101300	true

Environment variables are applied after the configuration file meaning anything specified as part of the environment overrides the configuration files.

Please Note: It is not possible to configure several sections at this time, these include but may not be limited to the rules section in access control, the clients section in the OpenID Connect identity provider, the cookies section of in session, and the authz section in the server endpoints.

Prefix

The environment variables must be prefixed with AUTHELIA_. All environment variables that start with this prefix must be for configuration. Any supplied environment variables that have this prefix and are not meant for configuration will likely result in an error or even worse misconfiguration.

Kubernetes

Please see the Kubernetes Integration: Enable Service Links documentation for specific requirements for using Authelia with Kubernetes.

Mapping

Configuration options are mapped by their name. Levels of indentation / subkeys are replaced by underscores.

For example this YAML configuration:

log:
  level: info
server:
  buffers:
    read: 4096

Can be replaced by this environment variable configuration:

AUTHELIA_LOG_LEVEL=info
AUTHELIA_SERVER_BUFFERS_READ=4096
