Here is the log of the error I am experiencing when trying to pull and run the image at https://registry.hub.docker.com/u/diameter/rtorrent-rutorrent/

The command failed.

 

Can anyone provide some assistance? Sorry I'm really new to this.

That's because he is not using the :latest tag.  He instead is using a :32 and a :64 tag.  So it didn't know which to get for you since you didn't specify a tag.  Normally when tags are not used it defaults to :latest.  Take a look at his docker registry.

Thank you for this information, but how do I get it to work?

You use one of the commands he has depending on the version you want from the link above.

 

Example, 64-bit:

Insecure

$ docker run -dt --name rtorrent-rutorrent -p 8080:80 -p 49160:49160/udp -p 49161:19161 -v ~/test:/downloads diameter/rtorrent-rutorrent:64

Secure

$ docker run -dt --name rtorrent-rutorrent -p 443:443 -p 49160:49160/udp -p 49161:19161 -v ~/test:/downloads diameter/rtorrent-rutorrent:64

Example, map both secure and insecure ports, 32-bit:

$ docker run -dt --name rtorrent-rutorrent -p 8080:80 -p 443:443 -p 49160:49160/udp -p 49161:19161 -v ~/test:/downloads diameter/rtorrent-rutorrent:32

But it seems you are running it from a template.  So edit the template to add either the :32 or the :64 tag to diameter/rtorrent-rutorrent.  So it should either be diameter/rtorrent-rutorrent:32 or diameter/rtorrent-rutorrent:64
