Troubleshooting unauthorized for Droplet setup

DockerDigitalOcean Droplets

I have been trying to resolve the following issue. Maybe someone could point me to additional documentation or some other setup step.

I have a droplet created with some basic setup. Docker is installed. The DigitalOcean command line tools are installed. I went through the following setup which includes commands for doctl auth list, auth init, and auth switch so that I can see and use/verify my registry:
https://www.digitalocean.com/docs/container-registry/quickstart/#push-to-your-registry. I have an API key that appears to be set up. However, after doing all that, I am stuck when trying to do a docker run command:
docker run -p 8089:8089 [private repo URL]
The error that comes up is:
“Error response from daemon: Get [private repo URL]: unauthorized: authentication required.”

The private repo URL is valid. Using the root user. Should I use a different user? I did look for documentation on user setup but could not find it. Sorry, if I missed it.

One thing to note is that I am not using Kubernetes integration yet. I am trying verify a basic docker run before I expand this setup with Kubernetes integration.

I was able to run the above docker command locally so I am trying to replicate this on the droplet. What am I missing?

Any assistance is greatly appreciated! Thanks in advance.

Hi,

I encountered the same problem being logged in to sudoer account and messed things up running doctl and docker with different privileges (user/root). I ran doctl as a regular user, and docker as a root. It was like that:

doctl registry login
Output
Logging Docker in to registry.digitalocean.com
sudo docker run registry.digitalocean.com/yannek-repo/testimage:1.0
Output
Unable to find image 'registry.digitalocean.com/yannek-repo/testimage:1.0' locally docker: Error response from daemon: Get https://registry.digitalocean.com/v2/yannek-repo/testimage/manifests/1.0: unauthorized: authentication required. See 'docker run --help'.

Everything started running fine when I set up doctl authentication with sudo command, and used it consequently since then.

I hope it gives you some clue.
