I own an orange pi pc and use LibreELEC with it. Is it possible to make the Docker-Addon working?

The advantage would be like:

I tried to compile the Docker-Addon but it says:

user@lenovo:~/LibreELEC_OPI$ PROJECT=H3 ARCH=arm scripts/create_addon docker
*** ERROR: service.system.docker: 'H3' not supported ***


Is it possible to compile the addon for orange pi LibreELEC? And how?

No, not possible. You need more recent kernel ... but there KODI does not work yet. It will soon: https://twitter.com/bootlincom/status/1005509009640706048
