如何在多个字段上使用with_items从ansible k8s模块中检索/解析结果

Question

团队，我的任务在json输出中运行良好，但我只想查找pod名称和名称空间，而不是输出整个pod json输出。因此，我正在使用debug来提取pod的名称，但不确定如何沿侧面名称空间提取所有pod的名称。

任何提示？我无法从这里理解：extracting a variable from json output then debug and register the outout with ansible

      - name: "Get a list of all pods from any namespace"
        k8s_facts:
          kind: Pod
          namespace: webhook
          kubeconfig: $WORKSPACE
          verify_ssl: no
        register: pod_list
      - debug:
          var: pod_list

      - name: list names and namespaces
        debug:
          msg: "{{ pod_list.resources[0].metadata.name }}"

输出：

TASK [3_validations_on_ssh : list names and namespaces] *******************************************************************************************************************************
ok: [target1] => {
    "msg": "k8s-webhook-auth-xxxx1"
}

寻找容器的样本输出片段如下：类似地，它在pod_lsit中继续用于其他容器

TASK [3_validations_on_ssh : debug] *****************************************************
ok: [target1] => {
    "pod_list": {
        "changed": false,
        "failed": false,
        "resources": [
            {

                        "release": "k8s-webhook-auth"
                    },
                    "name": "k8s-webhook-auth-xxxx1",
                    "namespace": "webhook",
                    "ownerReferences": [
                        {
                            "apiVersion": "apps/v1",
                            "blockOwnerDeletion": true,
                            "controller": true,
                            "kind": "DaemonSet",
                            "name": "k8s-webhook-auth",
                            "uid": "1e9-8e9b-ac1f6b4ea082"
                        }
                    ],
                    "resourceVersion": "47592900",
                    "selfLink": "/api/v1/namespaces/webhook/pods/k8s-webhook-auth-5jx6w",
                    "uid": "1e9-8e9b-ac1f6b4ea082"
                },
预期输出：

k8s-webhook-auth-xxxx1 webhook
k8s-webhook-auth-xxxx2 webhook
k8s-webhook-auth-xxxx3 webhook

我认为您需要一个循环来获取所需的确切输出，但这意味着它不会出现在单个“消息”中，而是每个窗格一个消息，例如：
