failed to push ghcr.io/foo/bar: failed to authorize: failed to fetch anonymous token

I had some issues with SSH connection being stale on deploys so i applied this suggestion and split my deployment task into two. Instead of calling kamal deploy, i now do kamal build push and kamal deploy separately. However, as long as just using kamal deploy works fine and deploys my app, once i prepend it with kamal build push call, deploy fails with a following error:

So, first of all - isn't the kamal deploy task calling build and push anyway? Is there anything special about calling these by hand that might break something with the tokens? And second of all, this error message is unclear to me, i have no idea what any sort of anonymous token has to do with my private repository kamal deployments and why an issue with it surfaces only when i split the calls.

I'm on Kamal 1.9.1

Any help much appreciated 🙏

Im trying to push to ghcr.io also but im not getting as yours. Did you create the PAT (Personal Access Token?

I would suggest trying to push the image from your local machine using the PAT created.

Create a PAT in github and then save it in a file called github_pat.txt as below

docker tag <your image name>/ghcr.io/<your-user>/your-image-name:tag
docker login ghcr.io -u <your-username> --password-stdin < github_pat.txt
docker push ghcr.io/<your-usernname>/your-image-name:tag

The steps below for me worked fine but im not able to deploy with kamal pushing to ghcr.io yet.

The error im getting is:

RROR: failed to solve: failed to push ghcr.io/my-user/my-image:d6105dead66710da6738468533b42b05324da93e: failed to authorize: failed to fetch oauth token: Post "https://ghcr.io/token": dial tcp: lookup ghcr.io on 10.255.255.254:53: no such host
