Question

团队，我在下面的任务中想在kubectl命令中使用节点名称，但是ansible正在对这些节点执行ssh。我不希望ssh发生在哪里，因为kubectl命令将在本地而不是在主机上运行。如何修改任务，使其仅使用其kubeclt命令中的节点名称？

 print(message_elements[0], message_elements[1], ...)

输出：

        shell: kubectl get node {{ item }} -o json
        ignore_errors: no
        register: node_info
        failed_when: node_info.rc == 0
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-gpu-node'] }}"
      - debug:
          var: node_info

预期输出：样品..

弄清楚：我不应该使用委托_来

        shell: kubectl get node {{ item }} -o json
        ignore_errors: no
        register: node_info
        failed_when: node_info.rc != 0
        with_items: "{{ groups['kube-gpu-node'] }}"
      - debug:
          var: node_info

组节点上的ansible循环with_items并避免ssh
