OPENWRT homeautomation openhab and home assistant

I am struggling to install several containers on my openwrt router.
I have installed a 64GB USB2.0 thumbdrive.
My overlay is correctly functioning.

Now I want to install several containers,
openhab
home assistant
adblock

I would like to run the two home automation systems in parallel to see which one I like the most.
I have heard good things about both.
but how to create several containers, and please see below, I can’t even set up the first one

Can someone please look at the message and tell me what is going wrong?

root@OpenWrt:~# ln -s /tmp/lib/docker /overlay
ln: /overlay/docker: File exists

thank you, I appreciate it

There is a reason why a supported platform matrix exists for docker’s official releases:
platform matrix https://docs.docker.com/engine/install/#supported-platforms

The kernels and os-packages of the listed systems are known to work perfectly with docker-ce build by Docker Inc. There is no official docker-ce for OpenWRT.

I would strongly suggest asking the maintainer of the OpenWRT dockerd package, and/or ask the OpenWRT community. It is more likely that they will know the problem and the solution to solve it.

that’s a good suggestion, thank you.
But I have seen openwrt questions being asked and answered here before.
Maybe I get lucky for once in my life?
