Hello everyone!

 

Is there anyone who tried to run Docker on armbian?

 

Ok, let's start from the beginning: I am from the Hypriot Team (we made Docker available on ARM) and recently saw some guys successfully playing with Docker on armbian. Meanwhile, we know, that our Docker runs at least on the Cubietrack and Lamobo R1/BananaPi R1 on top of armbian!

 

This is awesome because, you know, IoT is coming, and Docker on ARM helps get a grip on many challenges induced by IoT. However, we were only able to support Docker on Raspberry Pis so far...  Imagine if Docker would run on more than just a few ARM boards! Armbian seems an awesome platform to extend the family of Docker compatible boards.

 

So, I wonder if there is anyone who tried to run Docker on armbian?

 

If you are now curious about this topic and wanna get started, please see this blog post of how to install Docker on ARM within no time: http://blog.hypriot.com/post/family_arm_hardware_for_docker_more_children/

 

Looking forward to get in touch with you guys!

I have a Banana Pi M1+ running Debian jessie stable and am willing to give some time to install and test Docker for you if nobody else has volunteered with this hardware.

@MathiasRenner:

 

The deb-package you're refering is working fine on a BananaPi and Igor's image (self compiled). Don't know which additional information you need:

Yes, it's a huge improvement to see a cooperation between both projects!

@Skygod: I don't know how different M1+ is from M2, of which Hosteiner mentioned it works fine. If there is a difference, it would be cool to see it it works on the M1+ as well!

 

@Holsteiner: The Docker version in this image is probably by far not latest, but will probably work fine, which is good to see!

 

Performance of Docker? Like charm :-) See this is docker daemon without any containers:

$ ps -p 1277 -o %cpu,%mem,cmd
%CPU %MEM CMD
 1.1  2.8 /usr/bin/docker daemon -H fd:// --storage-driver=overlay -D

Let's start 20 webservers (https://hub.docker.com/r/hypriot/rpi-busybox-httpd/), i.e. starting 20 containers, and check again:

%CPU %MEM CMD
 6.5  3.4 /usr/bin/docker daemon -H fd:// --storage-driver=overlay -D

Note, that this is just the Docker daemon as "container manager" instance!

 

For each container, Docker starts 4 processes. Please do not ask me why. Let's rather have a look at CPU and RAM:

With 20 webservers running, CPU usage in total and average is about 4%. Before starting these 20 containers, it was a bit more than 2% in average.

RAM usage is 162 MB. Before starting the 20 containers, it was 46 MB.

 

So in general, only the Docker daemon is put on top. For containers, Docker's footprint is about the same as if you run apps natively. For this test, I used HypriotOS (http://blog.hypriot.com/) on a Raspberry Pi 2 B.

You also can define how much CPU and RAM a container is allowed to have at max, and also in relation to other containers. Docker offers many options to make sure you are in control about available resources.

 

And, BTW, with some tweaking, it's possible to start 2500 containers on a single Raspberry Pi with Docker :-) -> https://blog.docker.com/2015/10/raspberry-pi-dockercon-challenge-winner/

 

@September: I can see that several containers are running, which shows that Docker works well, awesome! Thanks for your feedback! Yeah, we are not sure yet how much work it is, but we at least try to get together...

Two very different beasts. (M1+ is more similar to the R1)

 

I can't test at the moment as my SD image is running with a kernel that is not supported.

ok :)

Thank you for the porting and the instructions.

I'm testing it on an Olimex A20-OLinuXIno-LIME2 (https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2/open-source-hardware) with armibian (jessie).

 

The installation worked. Just a remark, on running `apt-get -y install cgroupfs-mount` it removed the `console-common` package. Is this intended?

I can't install on a Orange Pi One, I try your Getting started guide from Hypriot and the guide from Docker to common Linux OS. I have many other Docker running on top of ARM boards: ODROID-C1 and ODROID-U3 and also an Android Stick TV UG802 with RK3066 processor using Picuntu.

Two thoughts:

 

1) Create a normal user (instead of user root) to run your docker container. Don't forget to add the newly created user to group 'docker'

2) Use the correct container images (armhf!), search a suitable image with command:

user@bananapi:~$ docker search armhf

Same issue as @op1tjaap:

See 'docker run --help'.

The Docker guys are waiting for a patch that affects the 4.5 kernel:

 

For some reason overlayfs on ext4 treated by kernel as "encrypted" volume in new kernels.

 

 

Going back to a 4.4x kernel makes Docker happy again. Loonix sucks donkey balls.

It's working with this patch - added:

That was quick, thank you Igor :)

 
The more I give the 4.x kernel a real-use try the faster I go back to 3.x. Btw Igor, I read in another thread that you run the forum on
single-board, which kernel are you using?
 
Given that the Cubietruck sucks as a media server, I'm thinking of turning it into a web/app/storage server. Kernel 4.x would make sense but
most things are still a cat-and-mouse chase. What would you suggest if you've had a Cubietruck?

Armbian Docker support is coming officially with next version and it would be pity if it is broken ;) Not long time ago I fixed all 3.10+ kernels which could run docker. Config has been tested almost on all.

 

Web server still uses legacy kernel 3.4.106, built one year ago ... since it's working without any problem I leave it as is. I plan to upgrade to some better hardware to get more responsiveness and with mainline kernel. It will be one of those single boards. For moderate usage Cubietruck should be just fine.

Hello,

 

I've been trying to get Docker to work with Armbian on Odroid xu4. Installation works but docker daemon wont start as it seems there are some modules missing from the kernel. Trying to start the daemon manually prints following output:

WARN[0001] Your kernel does not support cgroup memory limit 
WARN[0001] Unable to find blkio cgroup in mounts        
WARN[0001] Unable to find cpuset cgroup in mounts       
WARN[0001] mountpoint for pids not found                
FATA[0001] Error starting daemon: Devices cgroup isn't mounted 

This is with the latest Jessie server image: http://mirror.igorpecovnik.com/Armbian_5.14_Odroidxu4_Debian_jessie_3.10.102.7z

 

Any help appreciated!

I guess we forgot/failed to merge configuration. There is no other way than recompile kernel with proper configuration - to enable what's missing. I own one XU4 and that one is serving this forum so can't do the testing but will try to prepare a kernel update ASAP.

Good to see docker comming officially to armbian. Please does it run on the beelink x2, beelink m18 or the mxq pro or any of the tv boxes . Please could they be supported

Beelink x2 legacy kernel, which is currently the only working one), is too old for Docker but it will be possible with Vanilla kernels when they wlll be ready for H3 chipset.

 

On S905 based boxes which runs Odroid C2 kernel should alteady work.

oh ok thanks @lgor for the answer , i had thought as much for the S905 boxes but i have not got them yet. i was particularly happy at the coming of S905s to armbian, cos most of the heavy lifting have been done at odroids. 

please could you confirm if kodi could run too.. xeosal has adapted hw accelerated and 4k kodi to odroid C2.   http://forum.odroid.com/viewtopic.php?f=136&t=19433

KODI is not our field of interest so I can't confirm or deny ... but I read somewhere that Openelec is coming to those boxes, official or not. Don't know.
