Kubernetes Ansible 操作员：修补现有部署失败

Question

最近开始学习kubernetes和ansible

我有以下 kubernetes 命令来回滚

kubectl patch deployment -n my-namespace mydeployment --type='json' -p='[ {"op": "replace", "path": "/spec/template/spec/containers/0/image", "value":"127.0.0.1:5050/mydeployment:image_version"} ]

有没有办法在 kubernetes ansible 命令中引入 json 数组并修补我的部署？

我试过的是我剧本中的以下内容

- name: Demo
  k8s:
    api_version: apps/v1
    kind: Deployment
    state: present
    namespace: '{{ meta.namespace }}'
    name: my-operator
    definition: |
      spec:
       template:
         spec:
          containers:
            my-operator:
              image: {{ installed_software_image }}    
  register: output

由于容器是一个数组，补丁命令失败。我收到以下错误

NewReplicaSetAvailable\\\",\\\"message\\\":\\\"ReplicaSet \\\\\\\"my-operator-66ff64c9f4\\\\\\\" has successfully progressed.\\\"}]}}\": v1.Deployment.Spec: v1.DeploymentSpec.Template: v1.PodTemplateSpec.Spec: v1.PodSpec.Containers: []v1.Container: decode slice: expect [ or n, but found {, error found in #10 byte of ...|tainers\":{\"new-opera|..., bigger context ...|t\":\"2021-03-24T22:26:02Z\"}},\"spec\":{\"containers\":{\"my-operator\":\"image:\\\"27.0.0.1:5050/my-ope|...","field":"patch"}]},"code":422}\n'", "reason": "Unprocessable Entity", "status": 422}

有什么方法可以进行调试或打印实际发送到 kubernetes 服务器的命令吗？

Answer 1

错误表明“容器：”是一个数组。

尝试在“my-operaror:”前面添加“-”以表明它是数组中的第一项
