title: Alpha Configuration
---
:::warning
This page contains documentation for alpha features.
We reserve the right to make breaking changes to the features detailed within this page with no notice.
Options described in this page may be changed, removed, renamed or moved without prior warning.
Please beware of this before you use alpha configuration options.
:::
This page details a set of **alpha** configuration options in a new format.
Going forward we are intending to add structured configuration in YAML format to
replace the existing TOML based configuration file and flags.
Below is a reference for the structure of the configuration, with
[AlphaOptions](#alphaoptions) as the root of the configuration.
When using alpha configuration, your config file will look something like below:
```yaml
upstreams:
- id: ...
...: ...
injectRequestHeaders:
- name: ...
...: ...
injectResponseHeaders:
- name: ...
...: ...
```
Please browse the [reference](#configuration-reference) below for the structure
of the new configuration format.
## Using Alpha Configuration
To use the new **alpha** configuration, generate a YAML file based on the format
described in the [reference](#configuration-reference) below.
Provide the path to this file using the `--alpha-config` flag.
:::note
When using the `--alpha-config` flag, some options are no longer available.
See [removed options](#removed-options) below for more information.
:::
### Converting configuration to the new structure
Before adding the new `--alpha-config` option, start OAuth2 Proxy using the
`convert-config-to-alpha` flag to convert existing configuration to the new format.
```bash
oauth2-proxy --convert-config-to-alpha --config ./path/to/existing/config.cfg
```
This will convert any options supported by the new format to YAML and print the
new configuration to `STDOUT`.
Copy this to a new file, remove any options from your existing configuration
noted in [removed options](#removed-options) and then start OAuth2 Proxy using
the new config.
```bash
oauth2-proxy --alpha-config ./path/to/new/config.yaml --config ./path/to/existing/config.cfg
```
## Using ENV variables in the alpha configuration
The alpha package supports the use of environment variables in place of yaml keys, allowing sensitive values to be pulled from somewhere other than the yaml file.
When using environment variables, your yaml will look like this:
```yaml
providers:
- provider: azure
clientSecret: ${CLIENT_SECRET}
...
```
Where CLIENT_SECRET is an environment variable.
More information and available patterns can be found [here](https://github.com/a8m/envsubst#docs)
## Removed options
The following flags/options and their respective environment variables are no
longer available when using alpha configuration:
<!-- Legacy Upstream FlagSet -->
- `flush-interval`/`flush_interval`
- `pass-host-header`/`pass_host_header`
- `proxy-websockets`/`proxy_websockets`
- `ssl-upstream-insecure-skip-verify`/`ssl_upstream_insecure_skip_verify`
- `upstream`/`upstreams`
<!-- Legacy Headers FlagSet -->
- `pass-basic-auth`/`pass_basic_auth`
- `pass-access-token`/`pass_access_token`
- `pass-user-headers`/`pass_user_headers`
- `pass-authorization-header`/`pass_authorization_header`
- `set-basic-auth`/`set_basic_auth`
- `set-xauthrequest`/`set_xauthrequest`
- `set-authorization-header`/`set_authorization_header`
- `prefer-email-to-user`/`prefer_email_to_user`
- `basic-auth-password`/`basic_auth_password`
- `skip-auth-strip-headers`/`skip_auth_strip_headers`
<!-- Legacy provider FlagSet -->
- `client-id`/`client_id`
- `client-secret`/`client_secret`, and `client-secret-file`/`client_secret_file`
- `provider`
- `provider-display-name`/`provider_display_name`
- `provider-ca-file`/`provider_ca_files`
- `login-url`/`login_url`
- `redeem-url`/`redeem_url`
- `profile-url`/`profile_url`
- `resource`
- `validate-url`/`validate_url`
- `scope`
- `prompt`
- `approval-prompt`/`approval_prompt`
- `acr-values`/`acr_values`
- `user-id-claim`/`user_id_claim`
- `allowed-group`/`allowed_groups`
- `allowed-role`/`allowed_roles`
- `jwt-key`/`jwt_key`
- `jwt-key-file`/`jwt_key_file`
- `pubjwk-url`/`pubjwk_url`
and all provider-specific options, i.e. any option whose name includes `oidc`,
`azure`, `bitbucket`, `github`, `gitlab`, `google` or `keycloak`. Attempting to
use any of these options via flags or via config when `--alpha-config` is
set will result in an error.
:::important
You must remove these options before starting OAuth2 Proxy with `--alpha-config`

### LoginURLParameter
(**Appears on:** [Provider](#provider))
LoginURLParameter is the configuration for a single query parameter that
can be passed through from the `/oauth2/start` endpoint to the IdP login
URL. The "default" option specifies the default value or values (if any)
that will be passed to the IdP for this parameter, and "allow" is a list
of options for ways in which this parameter can be set or overridden via
the query string to `/oauth2/start`.
If _only_ a default is specified and no "allow" then the parameter is
effectively fixed - the default value will always be used and anything
passed to the start URL will be ignored. If _only_ "allow" is specified
but no default then the parameter will only be passed on to the IdP if
the caller provides it, and no value will be sent otherwise.
Examples:
# A parameter whose value is fixed
```
name: organization
default:
- myorg
```
A parameter that is not passed by default, but may be set to one of a
fixed set of values
```
name: prompt
allow:
- value: login
- value: consent
- value: select_account
```
A parameter that is passed by default but may be overridden by one of
a fixed set of values
```
name: prompt
default: ["login"]
allow:
- value: consent
- value: select_account
```
A parameter that may be overridden, but only by values that match a
regular expression. For example to restrict `login_hint` to email
addresses in your organization's domain:
```
name: login_hint
allow:
- pattern: '^[^@]*@example\.com$'
# this allows at most one "@" sign, and requires "example.com" domain.
```
Note that the YAML rules around exactly which characters are allowed
and/or require escaping in different types of string literals are
convoluted. For regular expressions the single quoted form is simplest
as backslash is not considered to be an escape character. Alternatively
use the "chomped block" format `|-`:
```
- pattern: |-
^[^@]*@example\.com$
```
The hyphen is important, a `|` block would have a trailing newline
character.
| Field | Type | Description |
| ----- | ---- | ----------- |
| `name` | _string_ | Name specifies the name of the query parameter. |
| `default` | _[]string_ | _(Optional)_ Default specifies a default value or values that will be<br/>passed to the IdP if not overridden. |
| `allow` | _[[]URLParameterRule](#urlparameterrule)_ | _(Optional)_ Allow specifies rules about how the default (if any) may be<br/>overridden via the query string to `/oauth2/start`. Only<br/>values that match one or more of the allow rules will be<br/>forwarded to the IdP. |

(**Appears on:** [Provider](#provider))
| Field | Type | Description |
| ----- | ---- | ----------- |
| `allowedTenants` | _[]string_ | AllowedTenants is a list of allowed tenants.

Or if the upstream were `file:///app`, a request for<br/>`/baz/info.html` would return the contents of the file `/app/foo/info.html`. |
| `uri` | _string_ | The URI of the upstream server. This may be an HTTP(S) server of a File<br/>based URL. It may include a path, in which case all requests will be served<br/>under that path.<br/>Eg:<br/>- http://localhost:8080<br/>- https://service.localhost<br/>- https://service.localhost/path<br/>- file://host/path<br/>If the URI's path is "/base" and the incoming request was for "/dir",<br/>the upstream request will be for "/base/dir". |
| `insecureSkipTLSVerify` | _bool_ | InsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.<br/>This option is insecure and will allow potential Man-In-The-Middle attacks<br/>between OAuth2 Proxy and the upstream server.<br/>Defaults to false. |
| `static` | _bool_ | Static will make all requests to this upstream have a static response.<br/>The response will have a body of "Authenticated" and a response code<br/>matching StaticCode.<br/>If StaticCode is not set, the response will return a 200 response. |
