request a helm chart, perhaps one for a small setup and one for an ha setup

SUMMARY

Here's my use case: I've got a kubernetes cluster running using xcp-ng, and I want to deploy clusterapi into it to use with deploying new clusters and managing their lifecycle. Apache Cloudstack has a provider that works with clusterapi (and xenserver). So, if I could deploy apache cloudstack into my kubernetes cluster, then I could use its provider... and I suspect, I might use it for a lot more after that.

My environments are all 100% kubernetes, essentially ... so to deploy this out means I'm going to have to build the containers and am looking to not reinvent the wheel, I'm not an apache cloudstack expert after all.

[lknite]

Am I supposed to just install apache cloudstack on the xcp-ng servers themselves? Am I pursuing this all wrong?

[DaanHoogland]

No @lknite you can but you are not supposed to install on a xenserver. If you do so it should be in a virtual machine and not on the dom0 . Your OS for the management server should be one of the supported OSses.

I do think you are going about this wrong though. You should not expect cloudstack to run on top of k8s but vice versa. ACS is supposed to manage you Xens for you and deploy the k8s clusters on them.

[telmich]

I have a question, are there anywhere helm charts for a complete cloudstack-on-kubernetes deployment similar to openstack-helm?

[lknite]

I may have succeeded but upon logging in and trying to configure it I broke everything networking related, so I'm not sure. I was trying to use cloudstack because it supports clusterapi.

When I get back home I'll share what I came up with.

[lknite]

Oh, looks like I built a container and deployed that into my cluster manually... see above. If I had gotten it to work I would have made a helm chart ...

[lknite]

I also thought about deploying cloudstack and using that instead of xenserver, but ended up installing vmware and using that... still open to cloudstack, tricky to get up to speed with it.
