The colibri board has only 4GB eMMC, when I try to download my docker image to the board it says “no space left on device” - the compressed image on dockerhub is 600MB.

df -H shows i have 2.6GB available but apparently its not enough.

I don’t have anything installed on the board except this image.
is there a way to resolve this? Can I just have the docker image on the SDCARD and how?

Hi @tcapoli,

It is possible to store docker images on an SD card or other external media, and in fact is something we are working on to document however it requires some configuration.

First of all though can you share what docker image you are trying to download? This seems rather large for a single image to need more than 2.6GB. Also can you run “docker images” on the device and see if there are any other container images present? If there are maybe try deleting those.
