Can't run the launcher to install Discourse on CentOS 7

In case anyone finds it handy in future:

How to set up Discourse on a server with existing Apache sites

Install Docker

I used the CentOS guide here: https://docs.docker.com/installation/centos (you only need to go as far as installing docker - you don’t need to pull any images)

Then start it, and set it to start on boot.
