installation

Installation

1. Add :ueberauth_keycloak_strategy to your list of dependencies in mix.exs:

    def deps do
      [{:ueberauth_keycloak_strategy, "~> 0.2"}]
    end

2. Add the strategy to your applications:

    def application do
      [applications: [:ueberauth_keycloak_strategy]]
    end

3. Add Keycloak to your Überauth configuration:

    config :ueberauth, Ueberauth,
      providers: [
        keycloak: {Ueberauth.Strategy.Keycloak, [default_scope: "read_user"]}
      ]

4. Update your provider configuration:

    config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
      client_id: System.get_env("KEYCLOAK_CLIENT_ID"),
      client_secret: System.get_env("KEYCLOAK_CLIENT_SECRET"),
      redirect_uri: System.get_env("KEYCLOAK_REDIRECT_URI")

5. Optionally configure the endpoint URL's so they reflect the correct host and realm:

    config :ueberauth, Ueberauth.Strategy.Keycloak.OAuth,
      # ... existing config
   
      # adapt host and realm in these URL's
      authorize_url: "<http://localhost:8080>/realms/<my-realm>/protocol/openid-connect/auth",
      token_url: "<http://localhost:8080>/realms/<my-realm>/protocol/openid-connect/token",
      userinfo_url: "<http://localhost:8080>/realms/<my-realm>/protocol/openid-connect/userinfo"

6. Include the Überauth plug in your controller:

    defmodule MyApp.AuthController do
      use MyApp.Web, :controller
   
      pipeline :browser do
        plug Ueberauth
        ...
       end
    end

7. Create the request and callback routes if you haven't already:

    scope "/auth", MyApp do
      pipe_through :browser
   
      get "/:provider", AuthController, :request
      get "/:provider/callback", AuthController, :callback
    end

8. You controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application on how to integrate other strategies. Adding Keycloak should be similar to Github.

calling

Calling

Depending on the configured url you can initial the request through:

/auth/keycloak

Or with options:

/auth/keycloak?scope=profile

config :ueberauth, Ueberauth,
  providers: [
    keycloak: {
      Ueberauth.Strategy.Keycloak, [
        default_scope: "profile"
      ]
    }
  ]
