Hi, has anyone successfully run docker on Rock3a?

Hi, has anyone successfully run docker on Rock3a?
When I install docker on rock3a, it says that installation is not successful, because cgroup, and some other features that I don’t remember are not supported. I am using official OS whose kernel version is 4.19.
Is this because the kernel is too old, or because the rock-chip’s modification to the kernel is too buggy?
Thanks for replying.

I’ve fixed this issue by this pull request: https://github.com/radxa/kernel/pull/11, which has got merged on 21 March. You should check your kernel build date by command uname -a

why not???,maybe you need new Linux OS

Hi, my uname -a output is:

Linux rock-3a 4.19.193-51-rockchip-gb2c01b3d79f2 #rockchip SMP Tue Jul 19 14:07:
56 UTC 2022 aarch64 GNU/Linux

It is build after Mar.21.

But when I install docker.io, it still shows error:

It says that my kernel does not support balabala features.
Where does the problem lie?
[/quote]

These kernel related logs are just warnings. But there is no useful info to locate the real root cause. Your kernel should be ok.

Finally I have found where the reason lies: docker uses iptables, but it can’t be compatible with iptables-nft, and it is only compatible with iptables-legacy.
