Hey All. 

TLDR: Every image I try to pull down for docker seems to only go to docker.io and I can't seem to find a way to change to any other domain.

 

I was recently having trouble downloading updates for my docker images.  Docker would say there is an update available but when I tried to download, it wouldn't get very far and come up with the following error:

Error: Tag latest not found in repository docker.io/binhex/arch-plexpass

 

I have several template repositories saved on Docker and none of them seem to be called when downloading the docker images.  For instance, I added the https://github.com/binhex/docker-templates to the template repositories.  When I click on add container, I can see all of the great templates there, but when I try to install any of them, it only calls docker.io not github, or any other repository.  When I trace the calls to docker.io, I can see a 301 redirect that I believe docker is not following, and even if it did, it would go to docker.com and the images are not there. 

 

I have been banging my head on this one for a while and can't seem to find any setting or config where docker.io is listed.  Today I stood up a new docker.img to see if that would fix the issue, but it seems to be doing the same thing. 

 

Can someone point me in the right direction?

 

Thanks

Install the community applications plugin.  Nobody used repositories anymore on unraid

 

For the layers from manifest error you have to delete the docker.img file.  See the docker FAQ

I have the community applications plugin installed.  I uninstalled and reinstalled (2016.12.31).  I deleted the docker.img file.  I tried to rerun any docker install from container or apps tab and I am still getting the docker.io domain call and the same error.

Only thing I can think of off the top of my head is to set static dns addresses in network settings

Yeah, that is what I thought.  So I pulled the IP for github and added it for docker.io in the /etc/hosts.  It didn't take.  I would assume it didn't like the host header of docker.io going to github.

 

So I did a little experimenting.  I had my network adapter DNS order set to 192.168.0.1 --> 8.8.8.8 --> 8.8.4.4.  I changed the order to 8.8.4.4 --> 8.8.8.8 --> 192.168.1.1 (I updated my local subnet)

 

Now everything comes up fine.  I am not even a novice at Docker so I don't understand why this worked, but now everything is functioning perfectly.  I assume that it tries querying and maybe only uses 1 of the DNS entries and when the Docker query doesn't respond it defaults to docker.io as the domain.  I splunk my local network traffic so I will comb through that to see if anything jumps out and post it here.  But for now I am back in business.
