GitHub Actions

We have a pack of GitHub Actions that let you manage an already running JetStream Server, useful for managing releases or standing up test infrastructure.

Full details and examples are in the jetstream-gh-actions repository, here's an example.

  # First we delete the ORDERS stream and consumer if they already exist

  # Now we create the Stream and Consumers using the same configuration files the 
  # nats CLI utility would use as shown above
