apb build fails

[glamperi]

This lab is great, until I get to the 'apb build' step. It does not specify where to run the apb commands, I ran them from the workstation set up for the lab. I ssh'd into workstation-43f9, and then I had to login as root to start the docker daemon for the build. When the build command is run, I get this:

apb build
Finished writing dockerfile.
Building APB using tag: [mysql-digital-ocean-apb]
Exception occurred! The command '/bin/sh -c yum-config-manager --disable rhel-7-server-htb-rpms && yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && yum -y update && yum -y install python git python-pip python-requests python-setuptools python-wheel && yum clean all' returned a non-zero code: 1

Any ideas?
