Run as a container #1
Comments
|
kdevops provides support for bringup: a) virtualization b) cloud c) bare metal In your case if you just want to run one container then treating your containers are bare metal would suffice if you are bringing them up yourself. So you just skip bringup and you define your own hosts file. That begs the question if kdevops should manage containers for you, and so then you'd instantiate the containers on a host, so a new bringup option. There is work by @fredlawl to get k8 support on kdevops but is not yet merged: https://github.com/fredlawl/kdevops/commits/k8s-integration So that may be an option. If not, then yet another option might be to leverage something else to bringup containers and instantiate them for us. |

Hannes just posted patches to enable large folios on bdev but using buffer-heads, allow us to easily ramp up to experiment with it. We currently crash on because of a: VM_BUG_ON_FOLIO(folio_test_large(folio), folio) on block_read_full_folio().

I'm trying to build / run kdevops in a container; however, that won't fly as it's trying to run libvirtd which obviously won't work as no systemd is running in that container (and it's questionable whether it should).
Any idea?
