feat: Support Flatcar OS and custom NTP servers #44

MAGNUM-2

by doing this, we're fully committing to Flatcar and not running anything on Ubuntu.

I think the cleaner thing is that we should create a variable called operatingSystem in the ClusterClass, and then in there, it can be an enum of either ubuntu or flatcar, by default it will be set to ubuntu.

And then, we should create a patch, conditional on operatingSystem being equal to flatcar to make all the changes that are needed for Flatcar, that way we can support both.

Then, we will have to update the driver to detect os_distro and use the appropriate model. Also, I think that means we'll also need to update the image builder script to allow building flatcar images and publish them too.

good progress, let's make sure to switch to patches on the ClusterClass as mentioned

Also, let's update title to be feat since this is a feature addition.

All patches are rendered exactly but now I am facing kcp unavailable issue. Seems kubernetes-sigs/image-builder#939 (comment) is not working. Btw, I need to dig more by jump into the machine. But key auth is not working with flatcar image. Created an issue to the upstream.

I close this kubernetes-sigs/image-builder#1018 and land openstack provider specific override in this driver.

+        # https://github.com/flatcar/Flatcar/issues/823
+        "ansible_user_vars": "oem_id=openstack",


nice catch here.

There is a lot of hacks around this because we're using an ISO image, @okozachenko1203 is going to contribute to image-builder an openstack image so that it uses OpenStack to deploy and publish directly to Glance.

Once we have that in place, we should switch the image builder to use that instead. It'll drive down the dependencies and we can remove this after.

this feels like it should live inside image-builder, so I think as a separate PR we should fix this?

The PATH modifying part should not be needed anymore since kubernetes-sigs/image-builder@f4864de, but I think dependence on coreos-metadata.service is platform-specific, so I don't think image-builder is a good place to put this.

Hello, Flatcar is now supported by CAPO - did you give a try with Magnum recently ? @mnaser I see you're in the #cluster-api-openstack Slack channel, do not hesitate to ping me if you need a hand on this topic. :)

mnaser · 2023-05-30T13:45:54Z

I think perhaps maybe if there's some documentation on building images and how clusters are defined for a flatcar system.. that would be helpful

tormath1 · 2023-05-30T17:40:10Z

@mnaser there is this documentation on the CAPO handbook: https://cluster-api-openstack.sigs.k8s.io/clusteropenstack/configuration.html#ignition-based-images to build and use Flatcar images (and as you know there is this issue: kubernetes-sigs/cluster-api-provider-openstack#1502)

Mazorius · 2023-07-07T09:49:35Z

I am waiting for the NTP fix as on autoscaling it is not possible to always change the internal NTP server.

Can the NTP fix be extracted so it can be merged @okozachenko1203 ?

mnaser · 2023-10-13T14:21:57Z

@Mazorius you shouldn't have any ntp issues with the latest images as you'll be getting the NTP server from DHCP, and the Flatcar part has been merged so I'm closing thsi
