Kubernetes ImagePullSecrets Failing with ImagePullBackOff

Question

我无法让Kubernetes提取我的私有docker映像

我在我的default命名空间中有一个名为regcred的kubernetes秘密，如下所示:

{"auths": {"index.docker.io": {"username": "Username", "password": "Password", "email": "[e-mail]", "auth": "VXNlcm5hbWU6UGFzc3dvcmQ="}}}

验证值为Username:Passwordb64编码。

这是我试图创建的pod，每次使用ImagePullBackOff都失败。

apiVersion: v1
kind: Pod
metadata:
name: private-reg
spec:
containers:
- name: private-reg-container
image: index.docker.io/jor2/hello-world:latest
imagePullSecrets:
- name: regcred

日志:

Error from server (BadRequest): container "private-reg-container" in pod "private-reg" is waiting to start: image can't be pulled

秘密是这样的:

你知道我哪里错了吗?

这是我的图像和pod规格需要的问题:

apiVersion: v1
kind: Pod
metadata:
name: private-reg
spec:
containers:
- name: private-reg-container
image: jor2/hello-world:latest
imagePullSecrets:
- name: regcred
