Kubernetes support: To work by default, ship a symlink in /usr/libexec #1193
Comments
The symlink for the directory in /usr/libexec has to be created like a file or otherwise it will land inside the existing directory (which shouldn't have existed). Fix the symlink creation. A better solution would be flatcar/Flatcar#1193 but that's for future releases.
with this we might be able to get rid of https://github.com/flatcar/mantle/blob/fbb5dee5e8e610cec56e7040c74bf2c6c1e3096a/kola/tests/kubeadm/templates.go#L365 |
@pothos How would I use your workaround for my setup (now)? I need to move |
You can ship the symlink with a systemd-sysext folder (or .raw image) like done here https://github.com/flatcar/sysext-bakery/blob/main/create_kubernetes_sysext.sh#L85 |
@pothos is there a way without using systemd-sysext? I didn't want to go down that rabbithole 🐇 🕳️ right now |
This is how you can configure an own path in Kubernetes |
Ok, doing something like that. Just figured I could maybe do this easier. Thank you! |
Current situation
Kubernetes tries to write files to
/usr/libexec/kubernetes/kubelet-plugins/volume/exec/
which fails on Flatcar.Workarounds were bind mounts or a sysext with a symlink.
Impact
Does not work by default.
Ideal future situation
/usr/libexec/kubernetes/kubelet-plugins/volume/exec
is a symlink to/var/kubernetes/kubelet-plugins/volume/exec
in the generic image. A tmpfile rule creates the symlink during image build time and also the target at runtime.The text was updated successfully, but these errors were encountered:
