【问题描述】:
团队, 我的任务在 json 输出中运行良好,但我只想查找 pod 名称和命名空间,而不是输出整个 pod json 输出。所以,我正在使用 debug 来提取 pod 名称,但不确定如何将所有 pod 名称沿边命名空间拉出..
有什么提示吗?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"
}
查找 pod 的示例输出 sn-p 如下:类似地,它会继续查找 pod_lsit 中的其他 pod
TASK [3_validations_on_ssh : debug] *****************************************************
ok: [target1] => {
"pod_list": {
"changed": false,
"failed": false,
"resources": [

"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
