Deploying k0s to alpine
There's a couple of extra things that need to be done before you can run the k0s installer on an alpine host:
Start by enabling cgroups v2 and reboot:
#enable cgroups2
echo "rc_cgroup_mode=\"unified\"" >> /etc/rc.conf
reboot
Now start the cgroups service and add it to the startup scripts:
rc-service cgroups start
rc-update add cgroups
Now finally we need to ensure that k0s can access the node's "machine ID":
apk add dbus
rc-service dbus start
rc-update add dbus
That's it! That's the minimum needed to have k0s deployed to an alpine host.
