Insights RBAC's goal is to provide an open source solution for storing roles, permissions and groups.
Full documentation is available through readthedocs. More info is available through platformdocs.
This is a Python project developed using Python 3.9. Make sure you have at least this version installed.
Additionally, the development environment installation requires the postgresql-devel package installed for your distribution before running properly.
To get started developing against Insights-rbac first clone a local copy of the git repository. :
git clone https://github.com/RedHatInsights/insights-rbac.gitDeveloping inside a virtual environment is recommended. A Pipfile is provided. Pipenv is recommended for combining virtual environment (virtualenv) and dependency management (pip). To install pipenv, use pip :
pip3 install pipenvThen project dependencies and a virtual environment can be created using :
pipenv install --devTo activate the virtual environment run :
pipenv shellPlease refer to Working with Openshift.
If deploying with Openshift seems overly complex you can try an alternate local environment where you will need to install and setup some of the dependencies and configuration.
This project is developed using the Django web framework. Many configuration settings can be read in from a .env file. An example file .env.example is provided in the repository. To use the defaults simply :
cp .env.example .envModify as you see fit.
PostgreSQL is used as the database backend for Insights-rbac. A docker-compose file is provided for creating a local database container. If modifications were made to the .env file the docker-compose file will need to be modified to ensure matching database credentials. Several commands are available for interacting with the database. :
# This will launch a Postgres container
make start-db
# This will run Django's migrations against the database
make run-migrations
# This will stop and remove a currently running database and run the above commands
make reinitdbAssuming the default .env file values are used, to access the database directly using psql run :
psql postgres -U postgres -h localhost -p 15432There is a known limitation with docker-compose and Linux environments with SELinux enabled. You may see the following error during the postgres container deployment:
"mkdir: cannot create directory '/var/lib/pgsql/data/userdata': Permission denied" can be resolved by granting ./pg_data ownership permissions to uid:26 (postgres user in centos/postgresql-96-centos7)If a docker container running Postgres is not feasible, it is possible to run Postgres locally as documented in the Postgres tutorial. The default port for local Postgres installations is 5432. Make sure to modify the .env file accordingly. To initialize the database run :
make run-migrationsYou may also run migrations explicitly, and in parallel, by specifying TENANT_PARALLEL_MIGRATION_MAX_PROCESSES (the number of concurrent processes to run migrations) and/or TENANT_PARALLEL_MIGRATION_CHUNKS (the number of migrations for each process to run at a time). Both of these values default to 2. Be mindful of the fact that bumping these values will consume more database connections:
TENANT_PARALLEL_MIGRATION_MAX_PROCESSES=4 TENANT_PARALLEL_MIGRATION_CHUNKS=2 ./rbac/manage.py migrate
Default roles and groups are automatically seeded when the application starts by default unless either of the following environment variables are set to 'False' respectively: :
PERMISSION_SEEDING_ENABLED
ROLE_SEEDING_ENABLED
GROUP_SEEDING_ENABLEDLocally these are sourced from /rbac/management/role/definitions/*.json, while the config maps in deployed instances are source from our RBAC config repo. If any changes to default roles/groups are required, they should be make there.
You can also execute the following Django command to run seeds manually. It's recommended that you disable db signals while running seeds with ACCESS_CACHE_CONNECT_SIGNALS=False. Caching will be busted after seeding for each tenant has processed. You may also specify the number of concurrent threads in which seeds should be run, by setting MAX_SEED_THREADS either in the process, or the app environment. The default value is 2. Be mindful of the fact that bumping this value will consume more database connections: :
ACCESS_CACHE_CONNECT_SIGNALS=False MAX_SEED_THREADS=2 ./rbac/manage.py seeds [--roles|--groups|--permissions]To run a local dev Django server you can use :
make serveTo run the local dev Django on a specific port use:
make PORT=8111 serveYou can make requests to RBAC locally to mimic traffic coming from the gateway, or locally within the same cluster from another internal service.
By default, with the DEVELOPMENT variable set to True, the dev_middleware.py will be used. This will ensure that a mock identity header will be set on all requests for you. You can modify this header to add new users to your tenant by changing the username, create new tenants by changing the account_number, and toggling between admin/non-admins by flipping is_org_admin from True to False.
This will allow you to simulate a JWT or basic-auth request from the gateway.
RBAC also allows for service-to-service requests. These requests require a PSK, and some additional headers in order to authorize the request as an "admin". To test this locally, do the following:
First disable the local setting of the identity header in dev_middleware.py by [commenting this line out](
insights-rbac/rbac/rbac/dev_middleware.py
Line 72 in b207668
Next, start the server with: :
make serve SERVICE_PSKS='{"catalog": {"secret": "abc123"}}'Verify that you cannot access any endpoints requiring auth: :
curl http://localhost:8000/api/rbac/v1/roles/ -vVerify that if you pass in the correct headers/values, you can access the endpoint: :
curl http://localhost:8000/api/rbac/v1/roles/ -v -H 'x-rh-rbac-psk: abc123' -H 'x-rh-rbac-account: 10001' -H 'x-rh-rbac-client-id: catalog'Change the 'x-rh-rbac-client-id', 'x-rh-rbac-psk' and 'x-rh-rbac-account' header values to see that you should get back a 401 (or 400 with an account that doesn't exist).
You can also send a request with the identity header explicitly in the curl command along with the service-to-service headers to verify that the identity header will take precedence.
Insights-rbac uses tox to standardize the environment used when running tests. Essentially, tox manages its own virtual environment and a copy of required dependencies to run tests. To ensure a clean tox environment run :
tox -rThis will rebuild the tox virtual env and then run all tests.
To run unit tests specifically:
tox -e py39To lint the code base :
tox -e lintFor all requests to the Insights RBAC API, it is assumed and required that principal information for the request be sent in a header named: x-rh-identity. The information in this header is used to determine the tenant, principal and other account-level information for the request.
Consumers of this API through cloud.redhat.com should not be concerned with adding this header, as it will be overwritten by the gateway. All traffic to the Insights RBAC API comes through Akamai and the Insights 3scale Gateway. The gateway is responsible for adding the x-rh-identity header to all authenticated requests.
Any internal, service-to-service requests which do not go through the gateway will need to have this header added to each request.
This header requirement is not reflected in the openapi.json spec, as it would cause spec-based API clients to require the header, which would be superfluously added to all requests on cloud.redhat.com.
This repository uses pre-commit to check and enforce code style. It uses Black to reformat the Python code and Flake8 to check it afterwards. Other formats and text files are linted as well.
Install pre-commit hooks to your local repository by running:
$ pre-commit install
After that, all your committed files will be linted. If the checks don’t succeed, the commit will be rejected. Please make sure all checks pass before submitting a pull request. Thanks!
Default roles can be found in the RBAC config repo.
