Would this work on an older version of a raspberry pi?

[Moosdijk]

Hi!

I came across this awesome project through Andreas Spiess' video and I was wondering if I can use this on an older 2B board.

It would really help me since I don't have to go out and buy a new one.

Thanks!

Only one way to know, give it a go and report :)

I dont know if it will run. As @Paulf007 says, please let us know and I can put a comment in the README for others to see.

In the past is did try installing docker on a Zero W and it just failed. It doesnt have the CPU power or the RAM anyways

When I get the chance this weekend, I'll try it out and let you know.
From what I can quickly google, it would work.

I 've tried on a raspberry pi 1 model B rev. 2 and I got the following errors:

pi@raspberrypi:~ $ docker-compose up -d

@olonsoft it may be that its just docker-compose that is incompatible. There could be a workaround. could you run docker run -d -p 1880:1880 --name mynodered nodered/node-red then see if you can navigate to :1880 in your browser.

docker-compose is by far the easiest way to go however if the above works then what i can do is build a script from the menu for the older devices that achieves the same goal.

This is what I got:

RPi Zero has a different version of the ARM processor, so it cannot run the same code. Processing power and RAM are secondary issues.

[gcgarner]

@olonsoft Thanks for testing the additional instruction but it doesn't look like it will work. It may be related to what @whatsupskip said, probably a CPU version problem

Just installed on a 3B and works fine on that

[olonsoft]

I 've also installed on a 3B and works fine for me too

[gcgarner]

This has been added to the README, closing issue

[olonsoft]

Just an update:
I read here: https://hub.docker.com/r/nodered/node-red

Note: RaspberryPI Zero and 1 users (Arm6 cpu) will need to use the specific tag name to install due to an upstream docker bug in the architecture detection. For example :

docker run -it -p 1880:1880 --name mynodered nodered/node-red:1.0.1-10-minimal-arm32v6
for the minimal node 10 version.

So I tried the above command and I could get nodered run.
But everything is so slow that does not worth the effort.

[gcgarner]

That's interesting. I tried to install docker on a zero about 6 months ago and it wouldn't even install. However it maybe related to a debian 9 issue. TBH i didnt spend too much time.

If you can get it to run great however i have my reservations on running docker on the zero and the A. RAM is one of the concerns and they dont have a lot of it.

I got a new zerow the other day any my plan is to use it as remote GPIO for the nodered running on my Pi 4. Either that or just install native nodered an publish the data via mqtt to my main nodered
