# dex - A federated OpenID Connect provider
|
|
|
|
|
|
|
|
__This is an experimental version of dex that is likely to change in
|
|
incompatible ways.__
|
|
|
|
dex is an OAuth2 server that presents clients with a low overhead framework for
|
|
identifying users while leveraging existing identity services such as Google
|
|
Accounts, FreeIPA, GitHub, etc, for actual authentication. dex sits between your
|
|
applications and an identity service, providing a backend agnostic flavor of
|
|
OAuth2 called [OpenID Connect](https://openid.net/connect/), a spec will allows
|
|
dex to support:
|
|
|
|
* Short-lived, signed tokens with predefined fields (such as email) issued on
|
|
behalf of users.
|
|
* Well known discovery of OAuth2 endpoints.
|
|
* OAuth2 mechanisms such as refresh tokens and revocation for long term access.
|
|
* Automatic signing key rotation.
|
|
|
|
Any system which can query dex can cryptographically verify a users identity
|
|
based on these tokens, allowing authentication events to be passed between
|
|
backend services.
|
|
|
|
One such application that consumes OpenID Connect tokens is the [Kubernetes](
|
|
http://kubernetes.io/) API server, allowing dex to provide identity for any
|
|
Kubernetes clusters.
|
|
|
|
## Getting started
|
|
|
|
dex requires a Go installation and a GOPATH configured. Clone it down the
|
|
correct place, and simply type `make` to compile dex.
|
|
|
|
```
|
|
git clone https://github.com/coreos/dex.git $GOPATH/src/github.com/coreos/dex
|
|
cd $GOPATH/src/github.com/coreos/dex
|
|
git checkout dev
|
|
make
|
|
```
|
|
|
|
dex is a single, scalable binary that pulls all configuration from a config
|
|
file (no command line flags at the moment). Use one of the config files defined
|
|
in the `examples` folder to start up dex with an in-memory data store.
|
|
|
|
```
|
|
./bin/dex serve examples/config-dev.yaml
|
|
```
|
|
|
|
dex allows OAuth2 clients to be defined statically through the config file. In
|
|
another window, run the `example-app` (an OAuth2 client). By default this is
|
|
configured to use the client ID and secret defined in the config file.
|
|
|
|
```
|
|
./bin/example-app
|
|
```
|
|
|
|
Then to interact with dex, like any other OAuth2 provider, you must first visit
|
|
a client app, then be prompted to login through dex. This can be achieved using
|
|
the following steps:
|
|
|
|
NOTE: The UIs are extremely bare bones at the moment.
|
|
|
|
1. Navigate to http://localhost:5555/ in your browser.
|
|
2. Hit "login" on the example app to be redirected to dex.
|
|
3. Choose the "mock" option to login as a predefined user.
|
|
4. Approve the example app's request.
|
|
5. See the resulting token the example app claims from dex.
