Rabbit Toolbox
https://github.com/Rauno56/rabbit-validator/I have commands to:
1. validate and test definition files.
2. compare definition files with the server's current configuration or another definition file.
3. deploy the definition file automatically.
The Toolbox is thus ideal for introducing GitOps practices to your RabbitMQ management.
