La tua installazione di Docker non funziona correttamente
Vedi: https://meta.discourse.org/t/docker-error-on-bootstrap/13657/18?u=sam
Per favore, come posso risolvere questo problema?
How did you install docker?
The host set up the forum for me but I have used the command below recently
wget -qO- https://get.docker.com/ | sh
I’ve tried the commands suggested there but problem persists 
Try contacting Your host asking how they installed discourse.
