# Configuration
|
|
Authelia has several methods of configuration available to it. The order of precedence is as follows:
|
|
|
|
1. [Secrets](./secrets.md)
|
|
2. [Environment Variables](#environment)
|
|
3. [Files](#files) (in order of them being specified)
|
|
|
|
This order of precedence puts higher weight on things higher in the list. This means anything specified in the
|
|
[files](#files) is overridden by [environment variables](#environment) if specified, and anything specified by
|
|
[environment variables](#environment) is overridden by [secrets](./secrets.md) if specified.
|
|
|
|
## Files
|
|
When running **Authelia**, you can specify your configuration by passing the file path as shown below.
|
|
|
|
```console
|
|
$ authelia --config config.custom.yml
|
|
```
|
|
|
|
You can have multiple configuration files which will be merged in the order specified. If duplicate keys are specified
|
|
the last one to be specified is the one that takes precedence. Example:
|
|
|
|
```console
|
|
$ authelia --config config.yml --config config-acl.yml --config config-other.yml
|
|
$ authelia --config config.yml,config-acl.yml,config-other.yml
|
|
```
|
|
|
|
Authelia's configuration files use the YAML format. A template with all possible options can be found at the root of the
|
|
repository [here](https://github.com/authelia/authelia/blob/master/config.template.yml).
|
|
|
|
## Environment
|
|
You may also provide the configuration by using environment variables. Environment variables are applied after the
|
|
configuration file meaning anything specified as part of the environment overrides the configuration files. The
|
|
environment variables must be prefixed with `AUTHELIA_`.
|
|
|
|
_**Please Note:** It is not possible to configure_ the _access control rules section or OpenID Connect identity provider
|
|
section using environment variables at this time._
|
|
|
|
_**Please Note:** There are compatability issues with Kubernetes and this particular configuration option. You must
|
|
ensure you have the `enableServiceLinks: false` setting in your pod spec. You can read more about this in the
|
|
[migration documentation](./migration.md#kubernetes-4300)._
|
|
|
|
Underscores replace indented configuration sections or subkeys. For example the following environment variables replace
|
|
the configuration snippet that follows it:
|
|
|
|
```
|
|
AUTHELIA_LOG_LEVEL=info
|
|
AUTHELIA_SERVER_READ_BUFFER_SIZE=4096
|
|
```
|
|
|
|
```yaml
|
|
log:
|
|
level: info
|
|
server:
|
|
read_buffer_size: 4096
|
|
```
|
|
|
|
# Documentation
|
|
|
|
We document the configuration in two ways:
|
|
|
|
1. The configuration yaml default has comments documenting it. All documentation lines start with `##`. Lines starting
|
|
with a single `#` are yaml configuration options which are commented to disable them or as examples.
|
|
|
|
2. This documentation site. Generally each section of the configuration is in its own section of the documentation
|
|
site. Each configuration option is listed in its relevant section as a heading, under that heading generally are two
|
|
or three colored labels.
|
|
- The `type` label is purple and indicates the yaml value type of the variable. It optionally includes some
|
|
additional information in parentheses.
|
|
- The `default` label is blue and indicates the default value if you don't define the option at all. This is not the
|
|
same value as you will see in the examples in all instances, it is the value set when blank or undefined.
|
|
- The `required` label changes color. When required it will be red, when not required it will be green, when the
|
|
required state depends on another configuration value it is yellow.
|
|
|
|
# Validation
|
|
|
|
Authelia validates the configuration when it starts. This process checks multiple factors including configuration keys
|
|
that don't exist, configuration keys that have changed, the values of the keys are valid, and that a configuration
|
|
key isn't supplied at the same time as a secret for the same configuration option.
|
|
|
|
You may also optionally validate your configuration against this validation process manually by using the validate-config
|
|
option with the Authelia binary as shown below. Keep in mind if you're using [secrets](./secrets.md) you will have to
|
|
manually provide these if you don't want to get certain validation errors (specifically requesting you provide one of
|
|
the secret values). You can choose to ignore them if you know what you're doing. This command is useful prior to
|
|
upgrading to prevent configuration changes from impacting downtime in an upgrade. This process does not validate
|
|
integrations, it only checks that your configuration syntax is valid.
|
|
|
|
```console
|
|
$ authelia validate-config configuration.yml
|
|
```
|
|
|
|
# Duration Notation Format
|
|
|
|
We have implemented a string based notation for configuration options that take a duration. This section describes its
|
|
usage. You can use this implementation in: session for expiration, inactivity, and remember_me_duration; and regulation
|
|
for ban_time, and find_time. This notation also supports just providing the number of seconds instead.
|
|
|
|
The notation is comprised of a number which must be positive and not have leading zeros, followed by a letter
|
|
denoting the unit of time measurement. The table below describes the units of time and the associated letter.
|
|
|
|
|Unit |Associated Letter|

# TLS Configuration
|
|
|
|
Various sections of the configuration use a uniform configuration section called TLS. Notably LDAP and SMTP.
|
|
This section documents the usage.
|
|
|
|
## Server Name
|
|
<div markdown="1">
|
|
type: string
|
|
{: .label .label-config .label-purple }
|
|
default: ""
|
|
{: .label .label-config .label-blue }
|
|
required: no
|
|
{: .label .label-config .label-green }
|
|
</div>
|
|
|
|
The key `server_name` overrides the name checked against the certificate in the verification process. Useful if you
|
|
require to use a direct IP address for the address of the backend service but want to verify a specific SNI.
|
|
|
|
## Skip Verify
|
|
<div markdown="1">
|
|
type: boolean
|
|
{: .label .label-config .label-purple }
|
|
default: false
|
|
{: .label .label-config .label-blue }
|
|
required: no
|
|
{: .label .label-config .label-green }
|
|
</div>
|
|
|
|
The key `skip_verify` completely negates validating the certificate of the backend service. This is not recommended,
|
|
instead you should tweak the `server_name` option, and the global option [certificates directory](./miscellaneous.md#certificates_directory).
|
|
|
|
## Minimum Version
|
|
<div markdown="1">
|
|
type: string
|
|
{: .label .label-config .label-purple }
|
|
default: TLS1.2
|
|
{: .label .label-config .label-blue }
|
|
required: no
|
|
{: .label .label-config .label-green }
|
|
</div>
|
|
|
|
The key `minimum_version` controls the minimum TLS version Authelia will use when opening TLS connections.
|
|
The possible values are `TLS1.3`, `TLS1.2`, `TLS1.1`, `TLS1.0`. Anything other than `TLS1.3` or `TLS1.2`
|
|
are very old and deprecated. You should avoid using these and upgrade your backend service instead of decreasing
|
|
this value.
