在ansible循环中删除stdout中返回的pods

Question

团队，

我正在尝试遍历所有返回的主机的pod并删除它们。

但出现错误。不知道我的循环是否正确？在节点上用kubectl拉吊舱。

输出：

ok: [node0117d] => {
00:11:05      "kos_pod": {
00:11:05          "changed": true, 
00:11:05          "cmd": "kubectl get pods -n kos-vdiskplugin  --no-headers --field-selector spec.nodeName=node0117d | grep -E kos-vdiskplugin-'[[:alnum:]]{5}' -o -w", 
00:11:05          "stdout": "kos-vdiskplugin-fps5b", 
00:11:05          "stdout_lines": [
00:11:05              "kos-vdiskplugin-fps5b"
00:11:05          ]
00:11:05      }
00:11:05  }
00:11:05  ok: [node0118d] => {
00:11:05      "kos_pod": {
00:11:05          "changed": true, 
00:11:05          "cmd": "kubectl get pods -n kos-vdiskplugin  --no-headers --field-selector spec.nodeName=node0118d | grep -E kos-vdiskplugin-'[[:alnum:]]{5}' -o -w", 
00:11:05          "stderr_lines": [], 
00:11:05          "stdout": "kos-vdiskplugin-dz794", 
00:11:05          "stdout_lines": [
00:11:05              "kos-vdiskplugin-dz794"
00:11:05          ]
00:11:05      }
00:11:05  }

任务：

- name: "fetch kos pod on node"
  shell: "kubectl get pods -n kos-vdiskplugin  --no-headers --field-selector spec.nodeName={{ inventory_hostname }} | grep -E kos-vdiskplugin-'[[:alnum:]]{5}' -o -w"
  register: kos_pod
  delegate_to: localhost
  become: false

- debug:
    var: kos_pod

- name: "Delete kos pod on node"
  command: kubectl delete pod -n kos-vdiskplugin "{{ item }}"
  delegate_to: localhost
  become: false
  with_items: "{{ kos_pod.stdout }}"`

错误输出：

Answer 1

我的表情中有错别字，导致失败。我不好，直到我发布问题，我才看到它。我的解决方案效果很好。

with_items: "{{ kos_pod.stdout }}"`

应该是

with_items: "{{ kos_pod.stdout }}"

Answer 2

[with_items需要一个list，但您给了它一个str

您想要：

with_items: "{{ kos_pod.stdout_lines }}"`
