Hello,  
I’m trying to resurrect Discourse on a CentOS 7 VM. It’s been a couple of days and I’ve learnt a lot but…

I keep coming up against the same problem no matter what I try. I have just cleaned up Docker:

```
docker kill $(docker ps -q)
docker rm $(docker ps -a -q)
systemctl restart docker
docker rm d509f29962eb
docker rmi $(docker images -q -f dangling=true)
docker rmi $(docker images -q)

```

I removed /var/discourse and re-cloned it:

```
git clone https://github.com/discourse/discourse_docker.git discourse

```

Then ran ./discourse-setup which complained that “DISCOURSE\_SMTP\_USER\_NAME was left blank”

I ran (and get the same result everytime) ./launcher bootstrap app :

[Output from bootstrap](http://c3iq.co.uk/output.txt)

Any ideas what I have missed?

Best regards.
