We're running microk8s on Red Hat 9 and saw the same problem during our patching for this cycle. The suggested fix of adding nf_conntrack
to modules.conf
has also corrected the issue on our end. Is there a long term fix coming for this issue?
Thanks!
We're running microk8s on Ubuntu 22.04 and saw this problem in different environments. The suggested fix of adding nf_conntrack
to modules.conf
has fixed our issue. We would appreciate a long-term fix.
Seeing this also with 1.29.4 (snap) on Ubuntu 22.04, single node cluster with Calico (and multus, if relevant). The modules.conf worked for me as well, but I have no idea what changed or why it didn't require this before.
We are experiencing the same issue with Microk8s 1.29.4 running on AWS EC2 with Ubuntu 22.04. The current workaround is to forcefully load the module however it's not clear what has changed since before and why we have to do this manually.
echo nf_conntrack | sudo tee /etc/modules-load.d/nf_conntrack.conf
I suddenly got the same issue on Ubuntu 24.04. The fix solved the issue for me also.

Summary
I added a node as a worker to a small cluster that had GPU enabled. It works fine initially, but on rebooting the node the
microk8s.daemon-kubelite.service
fails to start as it is unable to open/proc/sys/net/netfilter/nf_conntrack_max
:Adding
nf_conntrack
to the end of/etc/modules-load.d/modules.conf
in the worker node VM works around the issue.Nodes are all running Ubuntu Server 22.04.4 and microk8s v1.28.7 from snap. They run as VMs in a Proxmox cluster.
What Should Happen Instead?
Node should come up into Ready status after it is rebooted

Please contact me directly if this is required.
Can you suggest a fix?
Ensure the nf_conntrack module is loaded on worker nodes as it is on full nodes.
