使用Ansible在sysctl中设置多个值

我有一个剧本，里面有几个任务，将值设置为sysctl。如何使用sysctl模块在一个任务中设置所有值，而不是为每个设置一个任务

剧本片段：

- name: Set tcp_keepalive_probes in sysctl
  become: yes
  sysctl:
    name: net.ipv4.tcp_keepalive_probes
    value: 3
    state: present
    reload: yes

- name: Set tcp_keepalive_intvl in sysctl
  become: yes
  sysctl:
    name: net.ipv4.tcp_keepalive_intvl
    value: 10
    state: present
    reload: yes

- name: Set rmem_default in sysctl
  become: yes
  sysctl:
    name: net.core.rmem_default
    value: 16777216
    state: present
    reload: yes

定义var文件中的所有变量：

e、 g

。。。

剧本：

简单解决方案：将变量定义为dict

示例剧本：

---
- hosts: all
  gather_facts: false
  become: true
  vars:
    ansible_python_interpreter: /usr/bin/python3
    sysctl_config:
      net.ipv4.ip_forward: 1
      net.ipv4.conf.all.forwarding: 1
      net.ipv6.conf.all.forwarding: 1

  tasks:
   - name: Change various sysctl-settings
     sysctl:
       name: '{{ item.key }}'
       value: '{{ item.value }}'
       sysctl_set: yes
       state: present
       reload: yes
       ignoreerrors: yes
     with_dict: '{{ sysctl_config }}'

输出：

TASK [Change various sysctl-settings] **********************************************************************************************************************************************************************
changed: [10.10.10.10] => (item={'key': 'net.ipv4.ip_forward', 'value': 1}) => {
    "ansible_loop_var": "item",
    "changed": true,
    "item": {
        "key": "net.ipv4.ip_forward",
        "value": 1
    }
}
changed: [10.10.10.10] => (item={'key': 'net.ipv4.conf.all.forwarding', 'value': 1}) => {
    "ansible_loop_var": "item",
    "changed": true,
    "item": {
        "key": "net.ipv4.conf.all.forwarding",
        "value": 1
    }
}
changed: [10.10.10.10] => (item={'key': 'net.ipv6.conf.all.forwarding', 'value': 1}) => {
    "ansible_loop_var": "item",
    "changed": true,
    "item": {
        "key": "net.ipv6.conf.all.forwarding",
        "value": 1
    }
}

with_subelements

出现此错误：

subelements查找需要两个或三个项目的列表。将其替换为
with_items
有效。是的..我的坏子元素用于嵌套dict。with_items对于这种情况就足够了，因为ansible 2.7您应该使用循环：而不是with_items
