5.5.3 modules missing

[stucki]

I am trying to run Docker on Ubuntu 20.04 using this kernel. It seems to fail because iptables support is missing in the kernel:

root@mycloudex2:# /usr/bin/dockerd -D 
...
failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: modprobe: FATAL: Module ip_tables not found in directory /lib/modules/5.5.3-mvebu-tld-1-dirty
iptables v1.8.4 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

However, I according to that it was included as a module according to https://github.com/vzhilov/WDMC-Ex2-Ultra/blob/master/2.Kernel/kernel.config this was included as a module. So the problem is just that these files are currently missing...

Would you be willing to share these files? (I can build them on my own but I guess other users may need them too...)

Many thanks for your work! Amazing what can be done with these devices...

you have to install the modules built during the kernel build: see #4
