在k8s pod中应用任务

Posted 2021-05-04

我正在尝试运行kubectl -f pod.yaml但收到此错误。任何提示？

error: error validating "/pod.yaml": error validating data: [ValidationError(Pod): unknown field "imagePullSecrets" in io.k8s.api.core.v1.Pod, ValidationError(Pod): unknown field "nodeSelector" in io.k8s.api.core.v1.Pod, ValidationError(Pod): unknown field "tasks" in io.k8s.api.core.v1.Pod]; if you choose to ignore these errors, turn validation off with --validate=false

pod.yaml：

apiVersion: v1
kind: Pod
metadata:
  name: gpu-pod-10.0.1
  namespace: e6a5089f-8e9e-4647-abe3-b8d775079565

答案

你的pod.yaml定义中有imagePullSecrets的缩进错误，你需要为你的- name:指定imagePullSecrets。应该是这样的：

apiVersion: v1
kind: Pod
metadata:
  name: gpu-test-test-pod-10.0.1.11-e8b74730
  namespace: test-e6a5089f-8e9e-4647-abe3-b8d775079565
spec:
  containers:
  - name: main
    image: test.io/tets/maglev-test-bded587f4604
  imagePullSecrets:
  - name: testawsecr-cred
...

请注意，imagePullSecrets:是复数和array，因此您可以为多个注册表指定多个凭据。

如果您使用的是Docker，还可以在~/.docker/config.json中指定多个凭据。

如果您在imagePullSecrets:中具有相同的凭据并且在~/.docker/config.json中具有配置，则会合并凭据。
