Purpose

Captures and balances enterprise-subsidized transactions.

Getting Started

Developing

One Time Setup

# Clone the repository
git clone git@github.com:openedx/enterprise-subsidy.git
cd enterprise-subsidy
make dev.up.build-no-cache
./provision-enterprise-subsidy.sh

Go visit http://localhost:18280/admin/ and login with the standard edx/edx credentials to confirm that provisioning was successful.

Every time you develop something in this repo

# Grab the latest code
git checkout main
git pull

# start the docker containers
make dev.up.build # or docker-compose build --no-cache && make dev.up

# enter the app container shell
make app-shell

# Install/update the dev requirements
make requirements

# Run the tests and quality checks (to verify the status before you make any changes)
make test
# optionally make validate

# Now, back on your host...
# Make a new branch for your changes
git checkout -b <your_github_username>/<short_description>

# Using your favorite editor, edit the code to make your change.
# vim ...

# Run your new tests
make app-shell
pytest ./path/to/new/tests

# Run all the tests and quality checks
make validate

# Commit all your changes
# exit to your host again
git commit ...
git push

# Open a PR and ask for review.

Setting up openedx-events

Ensure you've installed the edx_event_bus_kafka and openedx_events requirements. Entering a shell with make app-shell and then running make requirements should install these for you.

From your host, run make dev.up.with-events, which will start a local kafka container for you. Visit http://localhost:9021/clusters to access the local "Confluent Control Center". Confluent is like a cloud wrapper around vanilla Kafka.

Your devstack.py settings should already be configured to point at this event broker, and to configure enterprise-subsidy as an openedx event consumer and/or produer.

Start by switching over to your enterprise-access repo and make sure it has requirements installed. We have a specific enterprise "ping" event and management command defined to test that your local event bus is well-configured. Open a shell with make app-shell and run:

./manage.py consume_enterprise_ping_events

This will consume ping events from the dev-enterprise-core topic. You may see a Broker: Unknown topic error the first time you run it. When you run your test event production below, that error will resolve (producing the event creates the topic if it does not exist). Leave the consumer running. You should see the enterprise-access-service as a registered consumer in your local confluent control center.

Now, go back to your enterprise-subsidy directory. Make sure requirements are installed, specifically the edx_event_bus_kafka and openedx_events packages. Use make app-shell in this repo and we'll produce a ping event:

./manage.py produce_enterprise_ping_event

If this event was successfully produced, you'll see a log message that says Message delivered to Kafka event bus: topic=dev-events-testing. You should also now see the dev-events-testing topic available in your local confluent control center, and even the test events that are being published to the topic.

Deploying

Merging a pull request will cause a GoCD build pipeline to start automatically. When the build pipeline is completed, the built image will be deployed to our staging environment automatically.

To deploy your change to the production environment, you must manually trigger the production enterprise-subsidy-prod pipeline, which will use the latest commit in the main branch by default.
