Trying to install some GEs in a FIWARE Lab machine, the installations doesn't complete using Centos base image.

I tried the same process on a local virtual machine and i could get successfully installed the docker container.

Triying to install the FIWARE PEP Proxy (building image) using the docker instructions:

sudo docker build -t pep-proxy-image .

I have full connectivity in host machine and also i opened the security rules on open-stack like web dashboard. Also I disabled the Centos firewall

systemctl disable firewalld

I have no problems if I download the image but i cant build on FIWARE Lab
Thanks in advance
