Pod定义:

apiVersion: v1
kind: Pod
metadata:
  name: test-pod
  labels:
    name: test
spec:
  containers:
    - image: 123.456.789.0:9595/test
      name: test
      ports:
        - containerPort: 8443
  imagePullSecrets:
    - name: my-secret

推荐答案

您需要使用kubectl create secret docker-registry my-secret --docker-server=123.456.789.0 ...创建密钥时，服务器必须与Pod定义中的内容完全匹配-包括端口号(并且如果是安全端口，则还必须与docker匹配) systemd中的命令行).

When you create the secret with kubectl create secret docker-registry my-secret --docker-server=123.456.789.0 ... the server must exactly match what's in your Pod definition - including the port number (and if it's a secure one then it also must match up with the docker command line in systemd).

此外，机密必须在创建Pod的相同命名空间中，但这似乎是有序的.

Also, the secret must be in the same namespace where you are creating your Pod, but that seems to be in order.
