As the documentation is now marked as obsolete, what is the correct way to install Docker on a recent Armbian Buster?

Welcome to Armbian 20.08.17 Buster with Linux 5.8.17-rockchip64

 

I think at one time, it was available in armbian-config, but I may be wrong.. And I'm trying that on an unsupported board (OrangePi4).

Here is what I have done:

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt update
sudo apt-get install docker-ce docker-ce-cli containerd.io
sudo docker run hello-world

Thanks.

[Werner]

I think I marked that point as outdated as it has not been revisited for a long time but also have no experience with docker whatsoever to change it.

So of anyone wants to change that please go ahead:https://github.com/armbian/documentation/edit/master/docs/User-Guide_Advanced-Features.md

[gounthar]

Done, thanks.

[lanefu]

the distro natively packaged versions are new enough for my use these days.. I just do apt install docker.io

[gounthar]

Thanks for the tip.

I will try it on another machine with a fresh install, as I get :

apt install docker.io

Hi. I am attempting to install  docker and I've hit a snag in the installation. I followed the instructions here: https://docs.docker.com/engine/install/ubuntu/

 

For some reason the docker service did not start. Here is the error from installation and the systemctl status:

I'm afraid the official documentation for Armbian is there: https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-run-docker

I have the same issue than ajkelsey with installation of Docker on an Orange Pi zero2 under Armbian_23.02.3_Orangepizero2_bullseye_legacy_4.9.318.

 

I tried the two methods described in the official documentation (https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-run-docker), but the docker service refuses to load.

 

Is there anything I'm missing? I was planning to try it on a fresh Armbian installation. I did not try to install Docker on Jammy and Bookworm because wifi does not work properly with these systems (available at https://www.armbian.com/orange-pi-zero-2/)

Docker needs some kernel stuff that has been introduced after 4.9.y was released. So the only way is to run a more recent kernel which probably does not support all hw features the board has to offer.

[Alligator427]

Thanks, Werner!

The official Armbian documentation states that the version should be 20.08.17 or newer, with Kernel 3.10 or higher.

I thought I was in the clear with Armbian_23.02.3_Orangepizero2_bullseye_legacy_4.9.318.

https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-run-docker

Perhaps this requirement applies to an older version of Docker. I'm considering trying a 1-2-year-old version of Docker to see if it works. Not sure if it makes sense.

 

I've attempted to install three different versions of Bullseye (edge and current) with a kernel >4.9 (5.15.x or 6.2), but none of them boot up on the Orange Pi Zero 2. Unfortunately, The only versions that boot up have kernel 4.9.

[Werner]

docs are most likely behind due to lack of maintenance (feel free to contribute!).

Docker wants cgroupsv2 which have been introduced in kernel 4.15.y

4.9.y is vendor kernel which might work better but is outdated and unmaintained:https://docs.armbian.com/User-Guide_FAQ/#why-does-hardware-feature-xy-work-in-old-kernel-but-not-in-more-recent-one

[ALIGMSTEN]

The only solution for legacy images is to downgrade to cgroups v1 with kernel parameter 

 

You add this in armbianEnv.txt

 

extraargs=systemd.unified_cgroup_hierarchy=0

 

 

To use cgroup v2, you need to have kernel 4.15 or later https://github.com/opencontainers/runc/blob/v1.0.0-rc95/docs/cgroup-v2.md#host-requirements.

 

Other requirements you might need to set iptables debian os

 

The docker installer uses iptables for nat. Unfortunately Debian uses nftables. 
You can convert the entries over to nftables or just setup Debian to use the legacy iptables.

sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy

 

 

As for non booting zero2 images please check latest, builds are working fine for me at this point, although I will check, (limited time atm, also 'not sure about mirrors synching').

[Alligator427]

Wow! Thanks ALIGMSTEN! This solve the issue completely. The last docker version is now working on Armbian bullseye kernel 4.9 on Orange pi zero2.

Thanks for your help and for what you are doing!

Here is the detailed procedure for the people that may experience the same issue.

 

-Fresh install of Armbian_23.02.3_Orangepizero2_bullseye_legacy_4.9.318.img.xz

http://xogium.performanceservers.nl/archive/orangepizero2/archive/Armbian_23.02.3_Orangepizero2_bullseye_legacy_4.9.318.img.xz

 

sudo apt-get update

sudo apt-get upgrade

 

-add the following to /boot/armbianEnv.txt

extraargs=systemd.unified_cgroup_hierarchy=0

 

-return to prompt

sudo update-alternatives --set iptables /usr/sbin/iptables-legacy

sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy

 

-reboot

 

-install docker according to https://docs.docker.com/engine/install/debian/ (below)

sudo apt-get update

sudo apt-get install ca-certificates curl gnupg

sudo install -m 0755 -d /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

 

-Then

echo \

  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \

  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \

  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

 

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

sudo reboot

 

-Test docker with

sudo docker run hello-world
