Ansible With_Together循环迭代

Question

我被困在尝试使用with_together并遍历多个列表的任务上。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的第一项，即（10.2.0.1）迭代process_list的第一项列表，即（8612,8622,8623,8625）中的所有4个项目，依此类推。

我在做什么是：-

task1.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 }}"

运行剧本时，得到以下输出：-

        "chdir": "/tmp",

    }
},
"_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

下面的任务完成了工作

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

给予

    "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"
