Setting up Registry with ghcr.io

[sebastianarena]

To Reproduce

I'm having trouble setting up the registry to use ghcr.io using my username and a token (classic) that I created for this specific purpose

1. If I set it up like this:

I will get the following error

Is it trying to upload to docker.io even though I configured something else?

2. Also if I try to put my Github Org Name as an image prefix, it will try to use that as the actual registry URL (I blurred my org name in the pictures)

Thanks for this amazing product

Current vs. Expected behavior

The image is uploaded to ghcr.io

Provide environment information

Operating System: Ubuntu 24.04 LTS
Dokploy: 0.10.10

Which area(s) are affected? (Select all that apply)

It seems that the dns resolution was modified on the server for some reason.

Recently I added steps for add ghcr account however I didn't have any issues, I will check but it seems like is more a dns error from the host

@Siumauricio thanks for the reply

I can't seem to make it work no matter what I do.

Here's an abstract of what it says when trying to upload it

As you can see, it says Login Successful, even testing like your docs says, shows a success, but later it fails.

I don't know why it says docker.io when it should be ghcr.io? or maybe that is correct because its just the name of the image?

Adding a prefix changes the path from /library/ to /prefix/ I don't think it's DNS otherwise it would fail login as well And the curious thing I noticed was that if I used my Github ORG name as a prefix (assuming it would upload the packages to my org not my username) shows the DNS error, like it's confusing which API to use if the Prefix = ORG name, which is weird.

Don't know what else to try. Let me know if this helps. Thanks.

try to remove the protocol in the url, it should look like : ghcr.io/your_image

@ouestlabs Good catch, very probably is because they are using https at the start of the registry url
