使用 Ansible 從字典中獲取簡化字典

Question

我有以下數據結構：

site_subnets:
    control: { network: "100.99.97.0/24", mtu: "1500", vm_start_offset: 0, dhcp_from_ip: "30", dhcp_to_ip: "50" }
    storage: { network: "100.99.98.0/24", mtu: "9000", vm_start_offset: 0, dhcp_from_ip: "30", dhcp_to_ip: "50" }
    mission: { network: "100.99.99.0/24", mtu: "9000", vm_start_offset: 0, dhcp_from_ip: "30", dhcp_to_ip: "50" }
    site:    { network: "100.99.0.0/16", mtu: "1500", dhcp_from_ip: "30", dhcp_to_ip: "50" }
    local:   { network: "100.99.44.1/22", mtu: "1500", dhcp_from_ip: "30", dhcp_to_ip: "50" }

我想最終得到一個看起來像這樣的新字典：

site_subnets_simplified:
  control: "100.99.97.0/24"
  storage: "100.99.98.0/24"
  mission: "100.99.99.0/24"
  site: "100.99.0.0/16"
  local: "100.99.44.1/22"

這是我寫的劇本：

 - set_fact:
     site_subnets_flat: "{{ site_subnets | combine | dict2items }}"

 - set_fact:
     site_subnets_simplified: "{{ site_subnets_simplified|default({}) + [ { item: item.network } ] }}"
   loop:
     - "{{ site_subnets_flat }}"

當我運行它時，我收到一個錯誤，上面寫着“unhashable type: 'list'”

有沒有更好或更簡單的方法來做到這一點？

Answer 1

例如，

  site_subnets_keys: "{{ site_subnets.keys()|list }}"
  site_subnets_vals: "{{ site_subnets|json_query('*.network') }}"
  site_subnets_simplified: "{{ dict(site_subnets_keys|zip(site_subnets_vals)) }}"

給

  site_subnets_simplified:
    control: 100.99.97.0/24
    local: 100.99.44.1/22
    mission: 100.99.99.0/24
    site: 100.99.0.0/16
    storage: 100.99.98.0/24
