# Configuration Introduction
|
|
|
|
How the Magic Happens
|
|
{: .subtitle }
|
|
|
|
|
|
|
|
Configuration in Traefik can refer to two different things:
|
|
|
|
- The fully dynamic routing configuration (referred to as the _routing configuration_, formerly known as the _dynamic configuration_)
|
|
- The startup configuration (referred to as the _install configuration_, formerly known as the _static configuration_)
|
|
|
|
Elements in the install configuration_ set up connections to [providers](../providers/overview.md) and define the [entrypoints](../routing/entrypoints.md) Traefik will listen to (these elements don't change often).
|
|
|
|
The _dynamic configuration_ contains everything that defines how the requests are handled by your system.
|
|
This configuration can change and is seamlessly hot-reloaded, without any request interruption or connection loss.
|
|
|
|
!!! warning "Incompatible Configuration"
|
|
Please be aware that the old configurations for Traefik v1.x are NOT compatible with the v2.x config as of now.
|
|
If you are running v2, please ensure you are using a v2 configuration.
|
|
|
|
## The Dynamic Configuration
|
|
|
|
Traefik gets its _dynamic configuration_ from [providers](../providers/overview.md): whether an orchestrator, a service registry, or a plain old configuration file.
|
|
|
|
Since this configuration is specific to your infrastructure choices, we invite you to refer to the [dedicated section of this documentation](../routing/overview.md).
|
|
|
|
!!! info ""
|
|
|
|
In the [Quick Start example](../getting-started/quick-start.md), the routing configuration comes from docker in the form of labels attached to your containers.
|
|
|
|
!!! info "HTTPS Certificates also belong to the routing configuration."
|
|
|
|
You can add / update / remove them without restarting your Traefik instance.
|
|
|
|
## The Static Configuration
|
|
|
|
There are three different, **mutually exclusive** (i.e. you can use only one at the same time), ways to define static configuration options in Traefik:
|
|
|
|
1. In a configuration file
|
|
1. In the command-line arguments
|
|
1. As environment variables
|
|
|
|
These ways are evaluated in the order listed above.
|
|
|
|
If no value was provided for a given option, a default value applies.
|
|
Moreover, if an option has sub-options, and any of these sub-options is not specified, a default value will apply as well.
|
|
|
|
For example, the `--providers.docker` option is enough by itself to enable the docker provider, even though sub-options like `--providers.docker.endpoint` exist.
|
|
Once positioned, this option sets (and resets) all the default values of the sub-options of `--providers.docker`.
|
|
|
|
### Configuration File
|
|
|
|
At startup, Traefik searches for static configuration in a file named `traefik.yml` (or `traefik.yaml` or `traefik.toml`) in:
|
|
|
|
- `/etc/traefik/`
|
|
- `$XDG_CONFIG_HOME/`
|
|
- `$HOME/.config/`
|
|
- `.` (_the working directory_).
|
|
|
|
You can override this using the `configFile` argument.
|
|
|
|
```bash
|
|
traefik --configFile=foo/bar/myconfigfile.yml
|
|
```
|
|
|
|
### Arguments
|
|
|
|
To get the list of all available arguments:
|
|
|
|
```bash
|
|
traefik --help
|
|
|
|
# or
|
|
|
|
docker run traefik[:version] --help
|
|
# ex: docker run traefik:v3.5 --help
|
|
```
|
|
|
|
Check the [CLI reference](../reference/install-configuration/configuration-options.md "Link to CLI reference overview") for an overview about all available arguments.
|
|
|
|
### Environment Variables
|
|
|
|
All available environment variables can be found in the [static configuration environment overview](../reference/install-configuration/configuration-options.md).
|
|
|
|
## Available Configuration Options
|
|
|
|
All the configuration options are documented in their related section.
|
|
|
|
You can browse the available features in the menu, the [providers](../providers/overview.md), or the [routing section](../routing/overview.md) to see them in action.
