I am not a RabbitMQ expert and could be wrong but I believe you want to mainly get /var/lib/rabbitmq/definitions.file.json then stop the daemon, do the backup then start it again?
You could try creating one by following the structure in the examples for other services. I have never done this myself so just an idea.
I also could not find any examples of a blueprint. Maybe K10 support will have one.
Hello @LucaDM
Thank you for using our K10 community.
Blueprint's templates can be found at https://github.com/kanisterio/kanister/tree/master/examples.
There is no blueprint for RabbitMQ at the moment, you could try building your own blueprint using other blueprint templates as a base, adding the steps you need to make the backup, i.e. scale down deployment, backup PVC and scale up, or any other actions needed in your case.
Also you can try a request via Github issue to get some guidance if you need some help with your blueprint.
Hope it helps
