Ansible变量循环

我对ansible很新,并且在我的剧本中遇到了变量继承/循环问题。该剧本用于为一些思科叶子配置vxlan vrfs和vxlan vlans。

以下是变量:

   username: admin
   password: password
   transport: cli

   vrfmember: DMZ_TOOLS
   vlan: 1000 ##starts here
   vlanname: DMZ_TOOLS_01
   vnsegment: 1000000
   mcastgroup: 225.1.1.1
   description: DMZ Tools Network 1
   ipaddress: 10.1.1.1/26    
   vlan: 1001 ##switches here
   vlanname: DMZ_TOOLS_02
   vnsegment: 1000001
   mcastgroup: 225.1.1.2
   description: DMZ Tools Network 2
   ipaddress: 10.1.1.2/26

这是剧本:

---
- name: meme
  hosts: all
  connection: local

  vars_files:
    - /root/ansible/examples/playbooks/vars_shit.yml

  tasks:

    - name: vlan config (vrf edition)
      nxos_command:
        commands:
          - conf t
          - vlan {{ vlan }}
          - name {{ vlanname }}
          - vn-segment {{ vnsegment }}
        provider: "{{ cli }}"

    - name: vrf config
      nxos_command:
        commands:
          - conf t
          - vrf context {{ vlanname }}
          - vni {{ vnsegment }}
          - rd auto
          - address-family ipv4 unicast
          - route-target both auto
          - route-target both auto evpn
        provider: "{{ cli }}"

    - name: int vlan
      nxos_command:
        commands:
          - conf t
          - interface {{ vlan }}
          - description {{ description }}
          - no shutdown
          - vrf member {{ vrfmember }}
          - no ip redirects
          - ip forward
          - no ipv6 redirects
        provider: "{{ cli }}"

    - name: int nve1
      nxos_command:
        commands:
          - conf t
          - member vni {{ vnsegment }}
        provider: "{{ cli }}"

    - name: router shit stoof
      nxos_command:
        commands:
          - conf t
          - router bgp 65490
          - vrf {{ vrfmember }}
          - address-family ipv4 unicast
          - advertise 12vpn evpn
        provider: "{{ cli }}"

    - name: vlan config
      nxos_command:
        commands:
          - conf t
          - vlan {{ vlan }}
          - name {{ vlanname }}
          - vn-segment {{ vnsegment }}
        provider: "{{ cli }}"

    - name: interface config
      nxos_command:
        commands:
          - conf t
          - interface nve1
          - member vni {{ vnsegment }}
          - suppress-arp
          - mcast-group {{ mcastgroup }}
        provider: "{{ cli }}"

    - name: evpn config
      nxos_command:
        commands:
          - conf t
          - evpn
          - vni {{ vnsegment }} l2
          - rd auto
          - route-target import auto
          - route-target export auto
        provider: "{{ cli }}"

    - name: int vlan config
      nxos_command:
        commands:
          - conf t
          - interface vlan {{ vlan }}
          - description {{ description }}
          - no shutdown
          - mtu 9216
          - vrf member {{ vrfmember }}
          - no ip redirects
          - ip address {{ ipaddress }}
          - no ipv6 redirects
          - fabric forwarding mode anycast-gateway
        provider: "{{ cli }}"

我正在尝试传递第一组cisco变量,一旦完成“ipaddress”,它将切换到第二组变量。 抱歉格式化,但任何帮助将不胜感激!

你可以创建像这样的东西

   username: admin
   password: password
   transport: cli

   interface:
     - vrfmember: DMZ_TOOLS
       vlan: 1000 ##starts here
       vlanname: DMZ_TOOLS_01
       vnsegment: 1000000
       mcastgroup: 225.1.1.1
       description: DMZ Tools Network 1
       ipaddress: 10.1.1.1/26    
     - vlan: 1001 ##switches here
       vlanname: DMZ_TOOLS_02
       vnsegment: 1000001
       mcastgroup: 225.1.1.2
       description: DMZ Tools Network 2
       ipaddress: 10.1.1.2/26

然后用

之类的东西循环遍历它
with_items:
  - '{{ interface }}'

并使用

访问任务中的变量
{{ item.vnsegment }}

您可能希望使用interface的第一项然后使用第二项执行所有三项任务,这样您就可以在名为.yml的{​​{1}}文件中执行任务,然后包含它

do_stuff.yml

这将允许您为一组配置执行一组任务。为了使它更容易理解,如果使用- include: do_stuff.yml with_items: - '{{ interface }}' 方法展开ansibles循环,将执行的任务将是:

do_stuff.yml

如果您不执行do_stuff.yml,只需在任务中添加- name: vlan config (vrf edition) // with interface[0] - name: vrf config // with interface[0] - name: int vlan // with interface[0] - name: int nve1 // with interface[0] - name: router shit stoof // with interface[0] - name: vlan config // with interface[0] - name: interface config // with interface[0] - name: evpn config // with interface[0] - name: int vlan config // with interface[0] - name: vlan config (vrf edition) // with interface[1] - name: vrf config // with interface[1] - name: int vlan // with interface[1] - name: int nve1 // with interface[1] - name: router shit stoof // with interface[1] - name: vlan config // with interface[1] - name: interface config // with interface[1] - name: evpn config // with interface[1] - name: int vlan config // with interface[1] ,则展开的循环将如下所示

with_items
