# UAA Extras

This application recreates the invite functionality that previously existed in UAA by using the /invite_users API endpoint.

## Installing the App

### Step One: Determine the URL for your instance of UAA Extras

You'll need to know where the app is going to be hosted, so you can tell UAA about it in the next step.

For example, if you'll be deploying into Cloudfoundry on BOSH-lite your url would probably be

### Step Two: Create a client in UAA for this app

This application uses oauth to perform actions on your behalf in UAA. To add a new oauth client in UAA, run the following command:

```shell
uaac client add uaa_extras_app \
--name "UAA Extras" \
--scope "scim.invite,password.write,cloud_controller.read" \
--authorized_grant_types "client_credentials,authorization_code" \
--authorities "scim.read,uaa.admin,password.write" \
--redirect_uri [url-from-step-one]/oauth/login \
-s [your-client-secret]
```

Remember the client-secret, you'll need it in step four.

If you are doing this within an already existing cloudfoundry deployment, you might want to create the user by editing your cf deployment with an opsfile like

### Step Three: Create redis service instance

Either create a locally running version of Redis, or create a service instance in Cloud Foundry if the app will be deployed there.

To create a service:

```shell
cf create-service redis32 standard-ha redis-accounts
```

### Step Four: Configure the app

The configuration is entirely read from environment variables. Edit the manifest.yml files and update your settings as neccessary. Download a copy of and place into `uaaextras/static`

### Step Five: Launch the app

#### Running in Cloud Foundry

This app was designed to deploy in Cloud Foundry:

```shell
cf push
```

## Local Development

Common development tasks are automated via the `dev` script.

### Development quickstart

1. Ensure you have pyenv and tox installed in isolated environments (e.g. install them with pipx)
2. Run `./dev venv` to bootstrap your virtualenvironment
3. Run tests with `./dev test`

Run tests with `./dev test`

### Dependency management

This project uses `pip-tools` for dependency management.

Abstract requirements live in pip-tools/requirements.in and pip-tools/requirements-dev.in.
Concrete requirements live in requirements.txt and requirements-dev.txt.

To add new requirements or pin versions, edit pip-tools/requirements.in and/or pip-tools/requirements-dev.in
then run `./dev update-requirements`

To bump versions, run `./dev upgrade-requirements`

After changing dependencies, you probably want to run `./dev clean`, which will recreate your virtuanenvironment
and clear your tox cache.

### Troubleshooting

If you run into an issue with `psycopg2` and you're working on a Mac running
Catalina or higher, make sure you've done the following:

- `brew install postgresql@12` and add the location to your path
- `brew install openssl@1.1` and add the location to your path

Note that `psycopg2` currently doesn't support PostgreSQL 13.x
(), and PostgreSQL 13.x
isn't available in AWS GovCloud yet, either.

Then export two environment variables in your current shell session:

- `export LDFLAGS="-L/usr/local/opt/openssl/lib"`
- `export CPPFLAGS="-I/usr/local/opt/openssl/include"`

To get a local server up, run the following command. Make sure you
properly setup the environment variables mentioned above in the
documentation.

```shell
./debug.py
```

### Configuring UAA Invites to leverage cloud.gov IdP

Because of the redirect that occurs for setting up cloud.gov multi-factor
authentication, the `IDP_PROVIDER_URL` must match what is coming from the UAA
login screen under `cloud.gov`.

![cloud.gov login button](./docs/cloud-gov-idp-screenshot.png)

#### A bit on the `/first-login` route

The `/first-login` route is used to redirect users with an origin of `cloud.gov`
to the cloud.gov IdP provider. This route is used to set the user's origin to
`cloud.gov` and the `externalId` to their `userName`. On a successful update of
the user, `cg-uaa-extras` will redirect to the `IDP_PROVIDER_URL` to complete
the user's authentication and TOTP token creation. This is why the URL from the
screenshot above is necessary for the `IDP_PROVIDER_URL`.

### Running tests

Tests are run using `tox` and `flake8`.

```shell
pip install tox
```

To run the tests, simply run `tox` from the root of the repository. If you run
into the same `psycopg2` setup issue as noted above in local development, make
sure you've followed the same steps and add the following line to each env
setting in the `tox.ini` file:

`setenv = LDFLAGS = "-L/usr/local/opt/openssl/lib"`

## Deployment

This repository leverages [Concourse](https://concourse-ci.org). The configuration
files all reside in the `ci/` directory. All pull requests should have `staging`
as a base branch which will automatically trigger a deployment for the staging
job. Once development is stable on `staging`, create a new pull request
promoting all the changes on `staging` to `master` to deploy the application in
the production environment.
