Automatic restart when changing definitions.json

[hfskappel]

Hi,
I use a configmap and a volumeMount to import a definitions.json to my RabbitMQ instance. This is done via ArgoCD. Is there any good way to make the pod restart the rabbitmq pod / reload the new config when the configMap is changed?

ArgoCD could either:

• perform kubectl rollout restart statefulset ... after generating the new JSON file
• or execute a command to import the definitions

Alternatively, you can use imports over HTTP and modify RabbitmqCluster resource definition with the updated file (eg the JSON filename could contain a version/timestamp that you'd update when it changes). Changes to RabbitmqCluster resource trigger a restart automatically.

You can also consider using https://github.com/rabbitmq/messaging-topology-operator.
