Question

显示“ xxx”的数据已被屏蔽。

问题描述：

成功方案：当我在Docker注册表中公开映像时，我的pod已成功创建。

失败情况：当我在Docker注册表中将映像设为私有时。我的映像拉取在kubernetes群集上失败。

请在下面提供详细信息和帮助。

我已将映像发布到Docker注册表。

以下是我的kubernetes秘诀：

c:\xxxxxxx\temp>kubectl get secret regcredx -o yaml
apiVersion: v1
data:
  .dockerconfigjson: xxxxxx
kind: Secret
metadata:
  creationTimestamp: 2018-10-25T21:38:18Z
  name: regcredx
  namespace: default
  resourceVersion: "1174545"
  selfLink: /api/v1/namespaces/default/secrets/regcredx
  uid: 49a71ba5-d89e-11e8-8bd2-005056b7126c
type: kubernetes.io/dockerconfigjson

这是我的pod.yaml文件：

apiVersion: v1
kind: Pod
metadata:
  name: whatever
spec:
  containers:
    - name: whatever
      image: xxxxxxxxx/xxxxxx:123
      imagePullPolicy: Always
      command: [ "sh", "-c", "tail -f /dev/null" ]
  imagePullSecrets:
    - name: regcredx

这是我在集群中的pod配置：

c:\Sharief\temp>kubectl get pod whatever -o yaml

Answer 1

Kubernetes找不到您的存储库，图像路径错误，您需要解决此问题：

image: xxxxxxxxx/xxxxxx:123

您可以尝试测试一种假设，即在要进行部署的节点上预拉映像。做docker images，记下正确的uri / repo：tag并在部署中对其进行更新。
