If this works you are in business:
$ git clone git@github.com:vmware-ac/uaa.git
$ cd uaa
$ mvn install
Each module has a mvn tomcat:run
target to run individually, or you
could import them as projects into STS (use 2.8.0 or better if you
can). The apps all work together the apps running on the same port
(8080) as /uaa
, /app
and /api
.
First run the uaa server as described above:
$ cd uaa
$ mvn tomcat:run
Then start another terminal and from the project base directory, run:
$ ./login.sh "localhost:8080/uaa"
And hit return twice to accept the default username and password.
This authenticates and obtains an access token from the server using the OAuth2 implicit
grant, similar to the approach intended for a client like VMC. The token is
stored in the file .access_token
.
Now kill the uaa
server and run the api
server (which starts the
uaa
server as well):
$ cd samples/api
$ mvn tomcat:run
And then (from the base directory) execute:
$ ./get.sh http://localhost:8080/api/apps
which should return a JSON array of (pretend) running applications.
With all apps deployed into a running server on port 8080 the tests
will include integration tests (a check is done before each test that
the app is running). You can deploy them in your IDE or using the
command line with mvn tomcat:run
.
For individual modules, or for the whole project, you can also run integration tests from the command line in one go with
$ mvn integration-test
(This might require an initial mvn install
from the parent directory
to get the wars in your local repo first.)
There are actually several projects here, the main uaa
server application and some samples:
-
uaa
is the actual UAA server -
api
(sample) is an OAuth2 resource service which returns a mock list of deployed apps -
app
(sample) is a user application that uses both of the above
In CloudFoundry terms
-
uaa
provides an authentication service plus authorized delegation for back-end services and apps (by issuing OAuth2 access tokens). -
api
isapi.cloudfoundry.com
- it's a service which provides resources which other applications may wish to access on behalf of the resource owner (the end user). -
app
iscode.cloudfoundry.com
orstudio.cloudfoundry.com
- a webapp that needs single sign on and access to theapi
service on behalf of users.
The authentication service is uaa
. It's a plain Spring MVC webapp.
Deploy as normal in Tomcat or your container of choice, or execute
mvn tomcat:run
to run it directly from uaa
directory in the source tree.
When running with maven it listen on port 8080.
It supports the APIs defined in the UAA-APIs document. To summarise:
-
The OAuth2 /authorize and /token endpoints
-
A /login_info endpoint to allow querying for required login prompts
-
A /check_token endpoint, to allow resource servers to obtain information about an access token submitted by an OAuth2 client.
-
SCIM user provisioning endpoint
-
OpenID connect endpoints to support authentication /userinfo and /check_id (todo). Implemented roughly enough to get it working (so /app authenticates here), but not to meet the spec.
Authentication can be performed by command line clients by submitting
credentials directly to the /authorize
endpoint (as described in
UAA-API doc). There is an ImplicitAccessTokenProvider
in Spring
Security OAuth that can do the heavy lifting if your client is Java.
By default uaa
will launch with a context root /uaa
. There is a
Maven profile vcap
to launch with context root /
.
There is a uaa.yml
in the application which provides defaults to the
placeholders in the Spring XML. Wherever you see
${placeholder.name}
in the XML there is an opportunity to override
it either by providing a System property (-D
to JVM) with the same
name, or an environment-specific uaa.yml
under
env['CLOUD_FOUNDRY_CONFIG_PATH']/uaa.yml
. When vcap is deployed the
CLOUD_FOUNDRY_CONFIG_PATH
is defined according to the way it was
installed.
All passwords and client secrets in the config files must be encypted
using BCrypt. In Java you can do it like this (with
spring-securty-crypto
on the classpath):
String password = BCrypt.hashpw("plaintext");
In ruby you can do it like this:
require 'bcrypt'
password = BCrypt::Password.create('plaintext')
The default is to use an in-memory, hash-based user store that is
pre-populated with some test users: e.g. dale
has password
password
and marissa
has password koala
.
To use a RDBMS for user data, activate the Spring profiles jdbc
and
one of hsqldb
or postgresql
. The opposite is !jdbc
which needs
to be specified explicitly if any other profiles are active. The
hsqldb
profile will start up with an in-memory RDBMS by default.
The active profiles can be configured by passing the
spring.profiles.active
parameter to the JVM. For, example to run
with an embedded HSQL database:
mvn -Dspring.profiles.active=jdbc,hsqldb,!legacy tomcat:run
Or to use PostgreSQL instead of HSQL:
mvn -Dspring.profiles.active=jdbc,postgresql,!legacy tomcat:run
To bootstrap a microcloud type environment you need an admin user.
For this there is a database initializer component that inserts an
admin user if it finds an empty database on startup. Override the
default settings (username/password=admin/admin) in uaa.yml
:
bootstrap:
admin:
username: foo
password: $2a$10$yHj...
email: admin@test.com
family_name: Piper
given_name: Peter
(the password has to be bcrypted).
There is a legacy mode where the CF.com cloud controller is used for
the authentication and token generation. To use this, launch the app
with Spring profile legacy
(a Maven profile with the same name is
provided for convenience as well). The opposite is !legacy
which
needs to be specified explicitly if any other profiles are active.
The cloud controller login URL defaults to
http://api.cloudfoundry.com/users/{username}/tokens
- to override it
provide a System property or uaa.yml
entry for
cloud_controller.login_url
.
An example resource server. It hosts a service which returns
a list of mock applications under /apps
.
Run it using mvn tomcat:run
from the api
directory (once all other
tomcat processes have been shutdown). This will deploy the app to a
Tomcat manager on port 8080.
This is a user interface app (primarily aimed at browsers) that uses
OpenId Connect for authentication (i.e. SSO) and OAuth2 for access
grants. It authenticates with the Auth service, and then accesses
resources in the API service. Run it with mvn tomcat:run
from the
app
directory (once all other tomcat processes have been shutdown).
