Issues with the lab environment for Config a Jenkins Pipeline

I get an error on the 3rd command: yum install -y --setopt=obsoletes=0 \ docker-ce-17.03.1.ce-1.el7.centos \ docker-ce-selinux-17.03.1.ce-1.el7.centos

it returns an error : 

failure: repodata/repomd.xml from download: [Errno 256] No more mirrors to try.

https://download./repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: download.; Name or service not known"

    try running a yum update -y first to make sure your yum is working.
