我在https://cloud.google.com/container-builder/docs/quickstart-docker关注教程。我已经建立了图像＆amp;它被推送到谷歌的gcr.io注册表。
$ gcloud auth configure-docker
gcloud credential helpers already registered correctly.
$ docker run --init gcr.io/foo-bar-111111/quickstart-image
Unable to find image 'gcr.io/foo-bar-111111/quickstart-image:latest' locally
docker: Error response from daemon: unauthorized: You don't have the needed permissions to perform this operation, and you may have invalid credentials. To authenticate your request, follow the steps in: https://cloud.google.com/container-registry/docs/advanced-authentication.

$ docker-credential-gcr configure-docker

$ docker run --init gcr.io/foo-bar-111111/quickstart-image

$ docker pull gcr.io/foo-bar-111111/quickstart-image:latest
Please login prior to pull:
error getting credentials - err: exit status 1, out: `docker-credential-gcr/helper: could not retrieve GCR's access token: credentials not found in native keychain`
我错过了什么？
答案 0 :(得分：2)
您将gcloud用作Docker credential helper：
gcloud auth configure-docker
因此，您必须使用gcloud docker来docker pull从Docker注册表中获取映像。 gcloud docker仍在下面使用Docker，但在移交给Docker之前，先向Docker客户端注入Container Registry凭据。
使用您的示例：
gcloud docker pull gcr.io/foo-bar-111111/quickstart-image:latest
您可能还必须使用sudo，使用完整的命令：
sudo gcloud docker pull gcr.io/foo-bar-111111/quickstart-image:latest
