I’m having this same issue trying to install 1.1.8 with k8s as well, has anyone figured out what is leading to this?

[btotharye]

Here is the output on my setup, seems like the contiv-netplugin keeps crashing:

[btotharye]

Here is some more information the container logs for that netplugin that is crashing shows this:

Initializing OVS
modprobe: ERROR: could not insert 'openvswitch': Exec format error

[dseevr]

This format error is caused by a version of modprobe that does not support compressed kernel modules... I can't remember what the solution was... I think alpine's modprobe doesn't support them?

[btotharye]

I got mine installing using modprobe openvswitch and now everything is loading correctly dashboard and all
