# BasicAuth
|
|
|
|
Adding Basic Authentication
|
|
{: .subtitle }
|
|
|
|
|
|
|
|
The BasicAuth middleware is a quick way to restrict access to your services to known users.
|
|
|
|
## Configuration Examples
|
|
|
|
```yaml tab="Docker"
|
|
# Declaring the user list
|
|
#
|
|
# Note: all dollar signs in the hash need to be doubled for escaping.
|
|
# To create user:password pair, it's possible to use this command:
|
|
# echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g
|

|
## Configuration Options
|
|
|
|
### General
|
|
|
|
Passwords must be encoded using MD5, SHA1, or BCrypt.
|
|
|
|
!!! tip
|
|
|
|
Use `htpasswd` to generate the passwords.
|
|
|
|
### `users`
|
|
|
|
The `users` option is an array of authorized users. Each user will be declared using the `name:encoded-password` format.
|
|
|
|
!!! note ""
|
|
|
|
- If both `users` and `usersFile` are provided, the two are merged. The contents of `usersFile` have precedence over the values in `users`.
|
|
- For security reasons, the field `users` doesn't exist for Kubernetes IngressRoute, and one should use the `secret` field instead.
|
|
|
|
```yaml tab="Docker"
|
|
# Declaring the user list

|
#
|
|
# Note: all dollar signs in the hash need to be doubled for escaping.

# To create a user:password pair, the following command can be used:
|
|
# echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g

|
|
|
|
### `usersFile`
|
|
|
|
The `usersFile` option is the path to an external file that contains the authorized users for the middleware.
|
|
|
|
The file content is a list of `name:encoded-password`.
|
|
|
|
!!! note ""
|
|
|
|
- If both `users` and `usersFile` are provided, the two are merged. The contents of `usersFile` have precedence over the values in `users`.
|
|
- Because it does not make much sense to refer to a file path on Kubernetes, the `usersFile` field doesn't exist for Kubernetes IngressRoute, and one should use the `secret` field instead.

|

```
|
|
|
|
### `realm`
|
|
|
|
You can customize the realm for the authentication with the `realm` option. The default value is `traefik`.
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.test-auth.basicauth.realm=MyRealm"

```
|
|
|
|
### `headerField`
|
|
|
|
You can define a header field to store the authenticated user using the `headerField`option.
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.my-auth.basicauth.headerField=X-WebAuth-User"
|
|
```
|
|
|
|
```yaml tab="Kubernetes"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: my-auth
|
|
spec:
|
|
basicAuth:
|
|
# ...
|
|
headerField: X-WebAuth-User
|
|
```
|
|
|
|
```json tab="Consul Catalog"
|
|
- "traefik.http.middlewares.my-auth.basicauth.headerField=X-WebAuth-User"
|
|
```
|
|
|
|
```json tab="Marathon"
|
|
"labels": {
|
|
"traefik.http.middlewares.my-auth.basicauth.headerField": "X-WebAuth-User"
|
|
}
|
|
```
|
|
|
|
```toml tab="File (TOML)"
|
|
[http.middlewares.my-auth.basicAuth]
|
|
# ...
|
|
headerField = "X-WebAuth-User"
|

```
|
|
|

headerField: "X-WebAuth-User"
|
|
```
|
|
|
|
### `removeHeader`
|
|
|
|
Set the `removeHeader` option to `true` to remove the authorization header before forwarding the request to your service. (Default value is `false`.)
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.test-auth.basicauth.removeheader=true"
|
|
