I am trying to build and run send4CAP as follows:
git clone https://github.com/Sen4CAP/Sen4CAP.git
cd docker/build/
./docker-run.sh

and then I get the following error

The command '/bin/sh -c yum -y install epel-release && yum -y update && yum -y install boost-devel

Unable to find image 'sen2agri-build:latest' locally
docker: Error response from daemon: pull access denied for sen2agri-build, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

What am I doing wrong?
Thanks in advance for your help
