[karl1@element ~]$ sudo vi /etc/modules-load.d/snap.microk8s.conf

Environment

  • Element Enterprise Installer 1.0.0

Resolution

Edit /etc/modules and add in there a new line: br_netfilter . This will load br_netfilter at boot time. sudo microk8s stop to stop MicroK8s services Edit /var/snap/microk8s/current/args/kube-proxy and remove the --proxy-mode completely. sudo modprobe br_netfilter to load the br_netfilter if not already loaded. sudo microk8s start to start MicroK8s services
