Initial startup

1. Start main Goteo's Docker-compose stack, so it's network is available for OAuth Docker service
2. Add these lines to your .env.local / .env.prod file (one connection to the OAuth DB, and another to Goteo DB):

GOTEO_DATABASE_URL=mysql://goteo:goteo@mariadb:3306/goteo?serverVersion=mariadb-10.2.43
OAUTH_DATABASE_URL=mysql://goteo:goteo@mariadb_oauth:3306/goteo_oauth?serverVersion=mariadb-10.2.43

3. Start Docker services: docker-compose up

Following startups

Run: docker-compose up

Access OAuth service:

Visit in your browser: http://localhost:52000 (52000 is the port specified in the Docker service for the OAuth2 server)

Requirements for ALL environments:

• PHP 8 is required
• Composer
• Node & NPM (tested in Node v14.17.0 and NPM 6.14.13 / 8.3.1)

Steps to create a pair of private/public keys and an encryption password:

These steps are meant to be executed inside the docker container.

You can access using docker-compose exec php-fpm /bin/bash

[⚠ WARNING: Probably not working with passphrase ⚠]

1. Generate private key: openssl genrsa -out private.key 2048

2. [Optional] Add passphrase to private key: openssl genrsa -aes128 -passout pass:_passphrase_ -out private.key 2048

3. Generate public key:

   • If you didn't use a passphrase: openssl rsa -in private.key -pubout -out public.key
   • [Optional] If you used a passphrase: openssl rsa -in private.key -passin pass:_passphrase_ -pubout -out public.key

4. Generate encryption key: php -r 'echo base64_encode(random_bytes(32)), PHP_EOL;'

5. Change file permissions of both keys: docker-compose run php-fpm chmod 644 public.key private.key

After above steps (generation of keys), edit the environment file (.env.local or .env.prod):

OAUTH2_PRIVATE_KEY_PATH=/absolute/path/private.key
OAUTH2_PRIVATE_KEY_PASSPHRASE=      # OPTIONAL, only if you used passphrase
OAUTH2_ENCRYPTION_KEY=EXAMPLE-ENCRYPTION-KEY
OAUTH2_PUBLIC_KEY_PATH=/absolute/path/public.key

IMPORTANT!

You need to create the OAuth2 client ID / secret pair, binding them to the GRANT TYPE you need (client credentials or password). Otherwise, it won't work.

Testing OAuth2 "client_credentials" grant (Postman):

Run all these commands under the Docker service. E.g.: docker exec goteo-oauth_php-fpm_1 composer install

1. Create an OAuth2 client: bin/console league:oauth2-server:create-client OAUTH2-CLIENT_CREDENTIALS --grant-type client_credentials. This will generate:
   1. Client ID
   2. Client secret
2. Open Postman and configure a request with the following authorization options:
   • Type: OAuth 2.0
   • Token name: Any name
   • Grant type: Use "Client Credentials"
   • Access Token URL: "http://127.0.0.1:52000/token"
   • Client ID: The one you've just obtained in step 1
   • Client secret: The one you've just obtained in step 1
   • Scope: Use "TEST", or any that's in config/packages/league_oauth2_server.yaml at the league_oauth2_server.scopes.available entry
   • Client Authentication: "Send as Basic Auth header"
3. Finally, click on "Get New Access Token" which should return an "Authentication complete" message, and then redirect you to a popup with the access token details.

Test OAuth2 "password_credentials" grant (Postman):

This grant type, allows us to generate an OAuth2 access token bound to a user (email and password must be provided in the same call).

Create a new OAuth2 client: bin/console league:oauth2-server:create-client OAUTH2-PASSWORD --grant-type password

At step 2, do the following:

• Grant type: "Password Credentials"
• Username: the user's email
• Password : Type the user's password

Test OAuth2 "authorization_code" grant (Postman):

Create an OAuth2 client like this: bin/console league:oauth2-server:create-client OAUTH2-AUTHORIZATION_CODE --grant-type authorization_code --redirect-uri http://127.0.0.1:52000/callback --allow-plain-text-pkce.

At step 2, do the following:

• Grant type: "Authorization Code"
• Callback URL: The one in the --redirect-uri parameter from the generated client => http://127.0.0.1:52000/callback
• Auth URL: http://127.0.0.1:52000/authorize
• State: Any string
