循环变量Ansible的多个值 [英] Looping multiple values for a variable Ansible
问题描述
我正在尝试为以下代码中使用的2个变量设置多个值:
I am trying to set multiple values for 2 variables that I am using in the following code:
- name: Create the subnets
os_subnet:
cloud: "{{ item.cloud }}"
state: present
validate_certs: no
no_gateway_ip: yes
enable_dhcp: yes
name: "{{ item.subnet }}"
network_name: "{{ item.network }}"
cidr: "{{ item.cidr }}"
allocation_pool_start: "{{ item.allocation_pool_start }}"
allocation_pool_end: "{{ item.allocation_pool_end }}"
host_routes:
- destination: "{{ item.destination | default(omit) }}"
nexthop: "{{ item.nexthop | default(omit) }}"
with_items:
- "{{ subnets }}"
tags: create_subnets
在我的环境中,某些子网具有不同数量的host_routes或没有.我的变量文件带有一个用于destination + nexthop的变量,现在看起来像:
In my environment, some subnets have a different number of host_routes or none. My variable file with one variable for destination+nexthop looks now like:
--- #
subnets:
- { cloud: tenant1, network: nw, subnet: nw_subnet, cidr: 172.10.10.224/27, allocation_pool_start: 172.10.10.228, allocation_pool_end: 172.10.10.254, destination: 10.10.10.0/24, nexthop: 172.10.114.125 }
这有效.但是,如果我的destination + nexthop值不止一个,该如何进行? 我还没有尝试过复制同一行并仅在最后的destination + nexthop中进行更改,但没有成功.如果我要在同一列表中同一行的另一行添加另一个destination + nexthop,它将只取最后一个值.
And this works. But if I am having more than one value for destination+nexthop, how shall I proceed? I have tried yet to duplicate the same line and change just in the end the destination+nexthop, but didn't worked. If I am trying add in the same list one the same row another destination+nexthop, it will take just the last value.
推荐答案
将host_routes
定义为子网变量中的列表:
Define host_routes
as list in the subnets variable:
subnets:
- allocation_pool_end: "172.10.10.254"
allocation_pool_start: "172.10.10.228"
cidr: 172.10.10.224/27
cloud: tenant1
host_routes:
- destination: 10.10.10.0/24
nexthop: "172.10.114.125"
- destination: YYY.YYY.YYY.YYY/ZZ
nexthop: XXX.XXX.XXX.XXX
network: nw
subnet: nw_subnet
- allocation_pool_end: "172.10.30.254"
allocation_pool_start: "172.10.30.228"
cidr: 172.10.30.224/27
cloud: tenant2
host_routes:
- destination: YYY.YYY.YYY.YYY/ZZ
nexthop: XXX.XXX.XXX.XXX
network: nw
subnet: nw_subnet2
现在您可以在任务中使用它
Now you can use it in your task
- name: Ensure subnets are present
os_subnet:
cloud: "{{ item.cloud }}"
state: present
validate_certs: no
no_gateway_ip: yes
enable_dhcp: yes
name: "{{ item.subnet }}"
network_name: "{{ item.network }}"
cidr: "{{ item.cidr }}"
allocation_pool_start: "{{ item.allocation_pool_start }}"
allocation_pool_end: "{{ item.allocation_pool_end }}"
host_routes: "{{ item.host_routes }}"
with_items:
- "{{ subnets }}"
tags: create_subnets
