我想从标准输出中获取一个键的值，并将其用作变量。这是我的剧本:
---
- name: Get bastion host info
hosts: localhost
connection: local
vars:
rgname: 'newrg'
bastionname: 'bhname'
tasks:
- name: Get bastion host info
shell: >
az network bastion show --name "{{ bastionname }}" --resource-group "{{ rgname }}"
register: bastionhost
- set_fact:
bh: "{{ bastionhost.stdout | regex_search ('dnsName(.+)', '\1') | first }}"
- name: Add bastion dnsName to group_vars file
ansible.builtin.lineinfile:
path: /home/user/group_vars/pprod.yml
line: 'ansible_ssh_common_args: ''-o ProxyCommand="ssh -W %h:%p -q user@"{{ bh }}""'''
create: yes
当我运行剧本时，这里是标准输出:
"stdout": "{n "dnsName": "bst-38b12345-fb01-60c0-ba73-dfb8f18a5f09.bastion.azure.com",n "etag": "W/\"402a91d0-74c2-41de-8d45-91eadab53d4a\"",n "id": "/subscriptions/1234578-1234-1234-5678-65e084b98765/resourceGroups/newrg/providers/Microsoft.Network/bastionHosts/bhname",n "ipConfigurations": [n {n "etag": "W/\"402a91d0-74c2-41de-8d45-91eadab53d4a\"",n "id": "/subscriptions/1234578-1234-1234-5678-65e084b98765/resourceGroups/newrg/providers/Microsoft.Network/bastionHosts/bhname/bastionHostIpConfigurations/bastion_ip_config",n "name": "bastion_ip_config",n "privateIpAllocationMethod": "Dynamic",n "provisioningState": "Succeeded",n "publicIpAddress": {n "id": "/subscriptions/1234578-1234-1234-5678-65e084b98765/resourceGroups/newrg/providers/Microsoft.Network/publicIPAddresses/pip",n "resourceGroup": "newrg"n },n "resourceGroup": "newrg",n "subnet": {n "id": "/subscriptions/1234578-1234-1234-5678-65e084b98765/resourceGroups/newrg/providers/Microsoft.Network/virtualNetworks/vnet/subnets/AzureBastionSubnet",n "resourceGroup": "newrg"n },n "type": "Microsoft.Network/bastionHosts/bastionHostIpConfigurations"n }n ],n "location": "southeastasia",n "name": "bhname",n "provisioningState": "Succeeded",n "resourceGroup": "newrg",n "tags": null,n "type": "Microsoft.Network/bastionHosts"n}",
剧中的台词:
"line": "ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q user@"": "bst-38b12345-fb01-60c0-ba73-dfb8f18a5f09.bastion.azure.com",""'",
文件中的结果:
user@Azure:~$ cat group_vars/pprod.yml
ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q user@"": "bst-38b12345-fb01-60c0-ba73-dfb8f18a5f09.bastion.azure.com",""'
user@Azure:~$
查看如何仅提取dnsName值(不带引号和逗号)，以便pprod。Yml将有:
ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q user@bst-38b12345-fb01-60c0-ba73-dfb8f18a5f09.bastion.azure.com"'
谢谢你的帮助。谢谢你
编辑:共享调试输出。我在一个文件中捕获json，以便更容易引用(敏感数据被屏蔽掉):
