Setting up private Docker registry

I'm running ProGet 5.1.22 on IIS and I'd like to set up a private docker repository. I folloed the instructions here but I'm having trouble setting up the SSL certificates on the server. The error looks like this when I try to log in from a docker client:

Error response from daemon: Get https://my_proget_server/v2/: x509: certificate signed by unknown authority

I'd like to know if it's possible to configure the ProGet server to use a plain HTTP registry, as shown in this docker guide: https://docs.docker.com/registry/insecure/

Product: ProGet
Version: 5.1.22

Unfortunately, the Docker client does not seem to support non-SSL connections (despite what their documentation says).

But based on that error, you just need to trust the certificate. This document shows you how to trust the self-signed certificate you created. That's probably what the signing error means.

note you need to reboot after trusting.

Thanks for the quick response Alana. I tried right-clicking the domain.crt file and installing it to the 'Trusted Root Certificate Authorities' and rebooting the server, but I still get the same error. When I use IIS Manager to edit the site bindings and point port 443 to the cert,

I should have asked one other thing - do I need to manually install the docker client onto the machine running the ProGet server? Or does the ProGet application handle everything?

Docker doesn't need to be installed on the server.

Your workstation (i.e. the docker client) needs to trust the certificate. So make sure to do that on your computer as well.

Thanks Alana, once I installed the certificate into my 'Trusted Root Certification Authorities' and restarted the docker daemon on my client machine, things are working nicely. Thanks again for your help!
