i’m tryng to run a docker version of cartodb on my raspberrypi3
with this command
docker run -d -p 3000:3000 -p 8080:8080 -p 8181:8181 sverhoeven/cartodb

all downloads are ok
but i recieve this error:

This is what I’d expect to see when trying to run a binary that doesn’t match the architecture of my current CPU.

Docker isn’t virtualization, so if you are running an arm version of docker, you’ll have to run images that have arm binaries inside them.

Cheers!

It’s totally doable.

There are a few arm binaries on the docker hub. You can search for ‘arm’ or ‘raspbian’ and get a bunch of results.

I have used some of the hypriot images while playing with docker on my pi: https://hub.docker.com/u/hypriot/

Basically, if you have a Dockerfile, you can change the FROM to be a base image that matches your architecture. I remember porting a FROM ubuntu image to a raspbian base image a long time ago. since raspbian and ubuntu are both debian descendants, it wasn’t too hard.

6

So the problem is not in the docker sverhoeven/cartodb

so i need to “port” that docker in arm version so i can run on raspberrypi3?

Can you give me some link to learn how to change that docker to work on rpi3?

There isn’t really a specific tutorial for it. It’s on par with “porting” an image FROM ubuntu to FROM debian– they are different base images, so you might need to change some of the other instructions. Another more extreme example would be “porting” a FROM centos image to a FROM debian image. In that case, the debian image won’t have yum installed, so you’d have to figure out the equivalent apt-get package names, etc.

It really isn’t much different to “port” an image to a base image that just happens to be built for another architecture. Open up the Dockerfile, change the base image, and try the docker build command. tweak and fix until it works.

As Suggested to me from Govinda Fichtner on Gitter
i’ve wget the github of cartodb-docker in my pi@raspberrypi:~/Desktop/cartodb/docker-cartodb

Then i edited the Dockerfile
changing FROM ubuntu:14.04 into FROM resin/rpi-raspbian:jessie

then i try:
pi@raspberrypi:~/Desktop/cartodb/docker-cartodb $ docker build -t=“sverhoeven/cartodb” ./

but:

You’ll probably need to apt-get install that package. The raspbian image probably doesn’t have it installed already, while the ubuntu image probably does.

Thx

no i’m
sudo apt-get install locales from pi

but i can add at the end on Dockerfile if it will work?

I don’t know enough about raspbian to say for sure what is going awry. Treat it like you were running it not inside a docker build and diagnose it that way.

now i’ve installed ubuntu mate 16.04 for rpi

this is docker info:
