Will kubeedge run on ARM devices like RaspberryPi?

[Vipin Krishna]

Hi everyone,

I'm Vipin Krishna. I have been trying to install kubeedge on RaspberryPi using this link.

 https://docs.kubeedge.io/en/latest/setup/installer_setup.html

But when i do the make command i'm getting about make file.

I'm using RaspberryPi 3b with Ubuntu mate installed in it. So when checked about i got this link  saying 

https://github.com/kubeedge/kubeedge/issues/883

Later i used gobuild command to build the binary and the binary was made successfully. but when i did keadm join it showed some syntax error. 

Please can any one help.

And also there is one more thing now i'm also installing kubeedge on my laptop(Ubuntu 1.04LTS ) which is considered as my master/cloud side. so when i do keadm init command after successfully cloning from the same link that i used for edge i am gettin this error.

Any tips would be helpful.

Thanks in advance.

Can anyone reply

[Hock Chye Teoh]

Hi Vipin,

I am also trying to run kubeedge on RaspberryPi. However, I am using Raspberry Pi 4.

What I did was recompile kubeedge/edge on the RaspberryPi, using "go" version go1.12.14.

My setup is:

1. Running cloudcore on Google Cloud Platform. Referring to https://kubeedge.readthedocs.io/en/latest/setup/installer_setup.html 

2. Running edgecore on Raspberry Pi 4. Also following https://github.com/kubeedge/kubeedge/issues/883 and https://docs.kubeedge.io/en/latest/setup/setup.html.

I got as far as this and now figuring out how to make use of this further.

What I intend to do:

1. Raspberry Pi 4 attached to:

i) dual camera

- To detect drowsiness and trigger alarm by sending sound to the local speaker

ii) speaker

2. Control from the cloud to activate or deactivate the drowsiness routine check

Hope this helps.

Hi Hock Chye Teoh

So what you are saying is Kubeedge can be installed on RaspberryPi or Cannot be installed on RaspberryPi? 

Because i didnt clearly understand.

Sorry to bother you.

[Teoh Hock Chye]

Hi Vipin,

Kubeedge can be install on Raspberry Pi. Not using the kdeam install method. U need to install kubernetes first then compile kubeedge for edge on Raspberry Pi (I am assuming u r installing edge on the Raspberry Pi).

Hi Teoh Hock Chye

I would like to discuss about this

 

[Vipin Krishna]

Yes i am trying to install edge part on kubeedge on RaspberryPi  

So, i first need to install kubernetes on RaspberryPi right?

After installing kubernetes i need to compile the edge of kubeedge right?

How do i compile that? Can you give a brief description?

Or is there any means i could discuss this with you?

Yes. Make sure to install the right "go" version on your RaspberryPi first. Mine uses version go1.12.14.

Follow guide on this link. https://docs.kubeedge.io/en/latest/setup/setup.html#setup-edge-side

For me, I just use this step.

1. cd $GOPATH/src/github.com/kubeedge/kubeedge

2. make all WHAT=edgecore 

Also, if u need mosquitto installed. Please do that as well. My setup requires mqtt.

This forum sends me email notifications and its a good place for discussion as others can also refer to this. I will take a look at it when I am free from my tasks. On the other hand, I am not too sure if I am helpful cause I haven't fully setup the entire thing yet. Maybe other much more experience experts can shed better light after seeing our discussion.

I am now at the part where I have to prepare pods. At the moment, its just cloud talking to edge.

But if u have other side questions, u can pm me. (I am new to this forum features too so we shall have to explore it)

But when i do this... i am make file error. The go version i'm using is go1.12.5

Yea i am hoping. 

I'm not using mosquitto or mqtt now i just want to create a raspberrypi cluster using kubernetes and kubeedge's edge should be running on RaspberryPi.

Can you provide a screenshot of the error or cut & paste the error here? Let's see if we can figure out what is missing. Hopefully, Raspberry Pi 3 & Raspberry Pi 4 don't have that much differences of libraries.

[Vipin Krishna]

These are the makefile error i am getting 

Makefile:10: recipe for target 'verify' failed

make: *** [verify] Error 127

Hi Vipin,

I didn't follow the whole thread, but installing on raspberrypi is pretty straightforward, my suggestion is just follow the standard setup steps for now, it's very simple. I am in a hackathon down here and we've installed on multiple pi devices with no problem.  

I am not sure about the state of the installer, it's probably good to avoid it for now.

NO you do not need to install k8s on the pi device just follow the link :  https://docs.kubeedge.io/en/latest/setup/setup.html#run-kubeedge

Start from ‘Deploy the edge node’

I am sorry it is such a mess, getting the installation better is the focus for us in the next two months. 

Sean

[Hock Chye Teoh]

This error is due to "go" is not in your PATH environment variable.

You can run this:

export PATH=$PATH:<"go" absolute path>

To test if it is working properly. Run this: which go

It should show u the go absolute path

After that you can repeat the make step again.

[Vipin Krishna]

Hi Hock Chye Teoh
My which go and GOPATH are same still i'm getting error. I have installed Raspbian Buster lite OS in one Pi and ubuntu mate in another both are showing the same error.

[Vipin Krishna]

When i followed the deploy the edge and did the make command this is the error i am getting.

[Hock Chye Teoh]

Are u using the arm version? I think you got the wrong binaries. For Raspbian, if not mistaken it is using arm version.

[Hock Chye Teoh]

https://github.com/kubeedge/kubeedge/releases -kubeedge-v1.1.0-linux-arm.tar.gz (this is the binary that runs on Raspbian)
