Ansible With_Together 循环迭代

Question

我陷入了一项任务，我试图使用 with_together 并循环访问多个列表。这是场景：-

我有两组数据：

"node_list": [
"10.2.0.1", 
"10.2.0.2",
]

"java_process_list": [ 
  [
   "8612",
   "8622",
   "8623",
   "8625"
  ], 
  [
   "8613",
   "8627",
   "8628",
   "8630"
  ] 
]

现在我希望我的node_list的第一个项目即（10.2.0.1）迭代process_list的第一个列表中的所有4个项目即（8612,8622,8623,8625）等等。

我正在做的是：-

任务1.yml：-

- name: Execute Script to grep IP address of dynamic nodes
  command: sh grep_nodes.sh
  args:
   chdir: "{{ somedir }}"
  register: result

- name: set fact
  set_fact: dynamic_nodes="{{ item }}"
  with_items: "{{ result.stdout_lines}}"
  register: items

- name: make a list
  set_fact: node_list="{{ items.results | map(attribute='ansible_facts.dynamic_nodes') | list }}"

- debug: var=node_list

- name: Get running java process of dynamic machines
  shell: ssh -i /tmp/key.pem {{item}} ps -ef | grep -v grep | grep -w java | grep GSC | awk '{print$2}'
  with_items: "{{node_list}}"
  register: process

- name: set fact
  set_fact: java_process="{{ item.stdout_lines }}"
  with_items: "{{process.results}}"
  register: items

- name: make a list
  set_fact: java_process_list="{{ items.results | map(attribute='ansible_facts.java_process') | list }}"

- debug: var=java_process_list

- name: Print items
  shell: 'echo {{item.0}}, echo {{item.1}}'
  args:
   chdir: "{{maindir}}"
  with_together:
    - "{{ dynamic_ip_list }}"
    - "{{ java_process_list }}"

当我运行剧本时，我得到以下输出：-

        "warn": true,
        "chdir": "/tmp",
        "stdin": null
    }
},
"_ansible_ignore_errors": null
}

预期结果：-

echo 10.2.0.1, echo 8612
echo 10.2.0.1, echo 8622
echo 10.2.0.1, echo 8623
echo 10.2.0.1, echo 8625

echo 10.2.0.2, echo 8613
echo 10.2.0.2, echo 8627
echo 10.2.0.2, echo 8628
echo 10.2.0.2, echo 8630 

Answer 1

下面的任务可以完成这项工作

    - debug:
        msg: "{{ item.0.key }}, {{ item.1 }}"
      with_subelements:
        - "{{ dict(nodes_list|zip(process_list))|dict2items }}"
        - value

给出

    "msg": "10.2.0.2, 8613"
    "msg": "10.2.0.2, 8627"
    "msg": "10.2.0.2, 8628"
    "msg": "10.2.0.2, 8630"
    "msg": "10.2.0.1, 8612"
    "msg": "10.2.0.1, 8622"
    "msg": "10.2.0.1, 8623"
    "msg": "10.2.0.1, 8625"
