RabbitMQ Deployment via OpenStack-Helm Script Encounters Failure

[Shivam Shukla]

[Issue]

The deployment script for OpenStack components such as RabbitMQ, Keystone etc. is failing.

[Issue Detail]

I executed the RabbitMQ deployment script from the OpenStack-Helm master branch, but the deployment failed with the following error:

<rabbitmq deployment script>
https://github.com/openstack/openstack-helm/blob/master/tools/deployment/component/common/rabbitmq.sh

<Error Message>

<rabbitmq pod logs>

Upon executing the deployment script, it creates the RabbitMQ pod “rabbitmq-cluster-wait-phbm7”. Although the pod is in a running state, the logs for this pod display the following message:

Similarly, the deployments for Keystone and several other components are also failing. What could be the possible reasons for these deployment failures?
