GCloud在拉取docker镜像时出错“无法拉取和解包镜像”

Question

我在GCloud中创建了一个新的私有节点，其中我有一个deployment.yml：

... 
containers:
  - name: print-logs
    image: busybox
    command: "sleep infinity"

当我查看相应的POD时，我总是得到这个错误："failed to do request: Head https://registry-1.docker.io/... timeout“

完整日志：

# kubectl describe pod <my_pod>

Warning  Failed     9s                kubelet            Failed to pull image "docker.io/library/busybox:latest": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/library/busybox:latest": failed to resolve reference "docker.io/library/busybox:latest": failed to do request: Head https://registry-1.docker.io/v2/library/busybox/manifests/latest: dial tcp 3.220.36.210:443: i/o timeout
Warning  Failed     9s                kubelet            Error: ErrImagePull

自定义设置：

gcloud container clusters create test-cluster \
                --preemptible \
                --enable-ip-alias \
                --enable-private-nodes \
                --machine-type n1-standard-2 \
                --zone europe-west4-a \
                --enable-cloud-logging \
                --enable-cloud-monitoring \
                --create-subnetwork name=main-subnet \
                --master-ipv4-cidr 172.16.0.32/28 \
                --no-enable-master-authorized-networks \
                --image-type COS_CONTAINERD

请帮帮我。

首先使用into连接到集群

gcloud container clusters get-credentials NAME [--internal-ip] [--region=REGION     | --zone=ZONE, -z ZONE] [GCLOUD_WIDE_FLAG …] 

然后尝试拉出docker的docker图像。
