Hi @chukka - since {{- if .Values.rabbitmq.enabled }} was removed we can no longer use the jfrog-platform helm chart to deploy artifactory (without any other jfrog application).

The migration hook will run even though we don't have rabbitMQ running and then fail, halting the deployment. Can the conditional be re-added or is there another solution so that we don't have to deploy rabbitmq?

[misse]

We're currently using this workaround successfully.

 rabbitmq:
    enabled: false
    migration:
      enabled: false
    rabbitmqUpgradeReady:
