What is the best way to install python-pip and docker-compose?

I have installed RHEL 7.4 and docker at the moment. I want to install docker-compose, but i could not find it in the repo. tried to install python-pip and did not find either.
I did some google search and looks like i need to register EPEL as repo, but my colleague said that is fedora repo and maybe not match what my RHEL 7.4 some stage.
Is centos version of docker-compose is better or i have to install from python source?
then using pip to install compose.

which way is better?

thanks in advance,

Kevin
