Hi Tony,

Sorry for the late response for your thread.

For you HTTPS issue, we (Catalyst Cloud) are using Magnum with HTTPS and it works.

For the 2nd issue, I think we were misunderstanding the nodes disk capacity. I was assuming you're talking about the k8s nodes, but seems you're talking about the physical compute host. I still don't think it's a Magnum issue because a k8s master/worker nodes are just normal Nova instances and managed by Heat. So I would suggest you use a simple HOT to test it, you can use this https://gist.github.com/openstacker/26e31c9715d52cc502397b65d3cebab6

Most of the cloud providers or organizations who have adopted Magnum are using Ceph as far as I know, just FYI.

Hi all, hope you are all keeping safe and well. I am looking for information on the following two issues that I have which surrounds Magnum project:

1. Magnum does not support Openstack API with HTTPS
2. Magnum forces compute nodes to consume disk capacity for instance data

My environment: Openstack Train deployed using Kayobe (Kolla-ansible). 

With regards to the HTTPS issue, Magnum stops working after enabling HTTPS because the certificate / CA certificate is not trusted by Magnum. The certificate which I am using is one that was purchased from GoDaddy and is trusted in web browsers (and is valid), just not trusted by the Magnum component. 

Regarding compute node disk consumption issue - I'm at a loss with regards to this and so I'm looking for more information about why this is being done and is there any way that I could avoid it?  I have storage provided by a Cinder integration and so the consumption of compute node disk for instance data I need to avoid. 

Any information the community could provide to me with regards to the above would be much appreciated. I would very much like to use the Magnum project in this deployment for Kubernetes deployment within projects. 

Thanks in advance, 

Regards,

Tony
