在循环中将ssh转换为json_query响应值

Question

团队，我收到json_query的响应，它是一个dict键：值，我想遍历所有值并为每个值运行ssh命令

以下获取了我所有节点的列表

- name: "Fetch all nodes from clusters using K8s facts"
k8s_facts:
  kubeconfig: $WORKSPACE
  kind: Node
  verify_ssl: no
register: node_list

- debug:
  var: node_list | json_query(query)
vars:
  query: 'resources[].{node_name: metadata.name, nodeType: metadata.labels.nodeType}'

任务[3_validations_on_ssh：调试]

ok: [target1] => {
    "node_list | json_query(query)": [
        {
            "nodeType": null,
            "node_name": "host1"
        },
        {
            "nodeType": "gpu",
            "node_name": "host2"
        },
        {
            "nodeType": "gpu",
            "node_name": "host3"
        }
    ]
}

要写的剧本：解析node_name并将其在ssh命令中用于所有1-3主机

- name: "Loop on all nodeNames and ssh."
shell: ssh -F ~/.ssh/ssh_config bouncer@{{ item }}.internal.sshproxy.net "name -a"
register: ssh_result_per_host
failed_when: ssh_result_per_host.rc != 0
with_item: {{ for items in query.node_name }}
- debug:
  var: ssh_result_per_host.stdout_lines

错误输出：

> The offending line appears to be:
        failed_when: ssh_result_per_host.rc != 0
        with_item: {{ for items in query.node_name }}
                    ^ here

当我执行循环时，解决方案2也会失败：

          shell: ssh -F ~/.ssh/ssh_config bouncer@{{ item.metadata.name }}.sshproxy.internal.net "name -a"
        loop: "{{ node_list.resources }}"
        loop_control:
          label: "{{ item.metadata.name }}"

输出溶胶2：

failed: [target1] (item=host1) => {"msg": "Invalid options for debug: shell"}
failed: [target1] (item=host2) => {"msg": "Invalid options for debug: shell"}
fatal: [target1]: FAILED! => {"msg": "All items completed"}

Answer 1

要扩展Ash的正确答案：

$company_id

另外，除非您确实只是想运行该一个 - name: "Fetch all nodes from clusters using K8s facts" k8s_facts: kubeconfig: $WORKSPACE kind: Node verify_ssl: no register: node_list - set_fact: k8s_node_names: '{{ node_list | json_query(query) | map(attribute="node_name") | list }}' vars: query: 'resources[].{node_name: metadata.name, nodeType: metadata.labels.nodeType}' - name: "Loop on all nodeNames and ssh." shell: ssh -F ~/.ssh/ssh_config bouncer@{{ item }}.internal.sshproxy.net "name -a" register: ssh_result_per_host with_items: '{{ k8s_node_names }}' 命令，否则ansible会通过add_host:来思考该问题：

ssh

这是一个人为的示例，因为如果您实际上只想获取kubernetes节点列表并在剧本中使用它们，则可以使用a dynamic inventory script

Answer 2

不是with_item，而是with_items
您不能使用with_item: {{ for items in query.node_name }} 将值保存到变量，然后在with_items: {{ new_variable }}

中使用该变量
