Quickstart

Prerequisites

• Make sure you've completed the Environment Setup first.

Starting the Software

1. Open two terminals and in each terminal, cd into the root directory of the hover-jet git repository.
2. In the each terminal, start a hoverjet container by running jet run
3. In the first terminal, run /jet/run/subscriber_demo_bq_main. You should briefly see some output at the start.
4. In the second terminal, run /jet/run/publisher_demo_bq_main.
5. You should now see messages printing periodically in the first terminal.

Explanation

• The PublisherDemoBQ connects to the pub/sub Broker and periodically publishes a message on the channel named demo_channel_name. The source for the PublisherDemoBQ is here: infrastructure/comms/tests/pub_sub_demo_bqs/publisher_demo_bq.cc
• The SubscriberDemoBQ connects to the pub/sub Broker and subscribes to messages on the channel named demo_channel_name. It periodically reads from this channel and prints the contents of the message received. The source for SubscriberDemoBQ is here: infrastructure/comms/tests/pub_sub_demo_bqs/subscriber_demo_bq.cc
• The message message sent between the two BQs is the DemoMessage, whose schema is defined here: infrastructure/comms/schemas/demo_message.hh. This message contains just a string value and a message header, which it inherits from the base Message class.
