Hi everyone, I'm hoping someone can help me figure out a docker auth issue I'm having. Using Rancher Desktop with nerdctl I'm getting 403 auth errors when trying to pull images from GCR. I'm logged in with nerdctl and was able to pull images when using dockerCLI. Any ideas?

Hi Josh, How do you login to GCR using nerdctl?

Also, do you need to be logged into pull from this registry?

I didn't log in explicitly to GCR. I did

nerdctl login

and then

gcloud auth configure-docker <http://us-central1-docker.pkg.dev|us-central1-docker.pkg.dev>

This works with the Docker CLI

is it possible for you to share the full

pull

command?

One sec, I switched back to docker cli earlier so I could unblock myself

nerdctl image pull <http://us-central1-docker.pkg.dev/[my-docker-image]|us-central1-docker.pkg.dev/[my-docker-image]> --debug

let me try few things from my end..

In general, if you have configured your

~/.docker/config.json

to use credential helpers then there's no need to explicitly login using

docker login

nerdctl login

.. You can directly execute commands such as

push

that need authentication .. and the CLI in the background makes use of the credential helpers to get the login token and perform the operations..

For GCP, your

~/.docker/config.json

could look something like..

Copy code

{
  "credsStore": "wincred",
  "credHelpers": {
    "us-central1-docker.pkg.dev": "gcloud"
  }
}

... and you can then authenticate with GCP using below commands before running any

docker

nerdctl

commands that need authentication..

Copy code

gcloud auth login
gcloud auth activate-service-account  <your-service-account-id>@<your-organization>.<http://iam.gserviceaccount.com|iam.gserviceaccount.com>  --key-file=your-key-file.json

That makes sense in principle, but I'm not sure why it's not working for me. I assure you I'm authed into gcloud

And was able to pull the images just fine when using the dockercli

My config file looks like:

Copy code

{
  "auths": {
    "<https://index.docker.io/v1/>": {}
  },
  "credsStore": "desktop",
  "credHelpers": {
    "us-central1-docker.pkg.dev": "gcloud"
  }
}

Any other ideas?

Your config file looks as expected to me.. I need to try few things myself before i can suggest something..

Hi, for some reason, my desktop environment is broke and couldn't investigate this.. Hopefully I get my env working again soon and I will continue the investigation.. Please hang in there.
