Hello,
We are implementing the auto-healing workflow captured here - https://github.com/openstack/heat-templates/tree/master/hot/autohealing
We are deploying a Heat auto-scaling group that scales a template that contains the needed services and the Nova resource. The template contains a Zaqar queue, Mistral trigger and Mistral workflow. We are also using a scaling policy to scale up and down the template resources.
This is working fine, but we are experiencing an issue with scaling up the auto-scaling group via 'openstack stack resource signal <stack> <scaling_policy>. If the Heat stack is update with a larger value, the resources are added correctly. It is only when using the scaling policy. Logs show a forbidden error when attempting to create the Zaqer Mistral trigger. Any ideas?
