Error during CKAN build process with docker compose:

Pulling datapusher (clementmouchet/datapusher:)...

What steps can be taken to reproduce the issue?

sudo docker-compose up -d --build

Here is a known image that has this problem:
https://hub.docker.com/r/clementmouchet/datapusher

Using Python version 2.7.8.

FWIW: I've build this a year ago
https://hub.docker.com/r/vanuan/ckan-datapusher/dockerfile

[Vanuan]

A, wait. I don't see why you would need it: https://hub.docker.com/r/clementmouchet/datapusher/dockerfile

Just don't use an image, put the Dockerfile locally.

Change this line to build specification by copying the dockerfile locally:

ckan/contrib/docker/docker-compose.yml

Line 47 in 6660a9f

image: clementmouchet/datapusher

any reason why we use datapusher from clementmouchet instead from ckan itself?
