How to apply right filter to get list of variables to an jinga variable with correct indentation
问题
以下是翻译好的部分：
我有一个在Ansible角色中使用变量的模板，这些变量在vars.yaml中定义。
模板如下所示：
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
{{ vm_routes }}
vm_routes的变量在vars.yaml中传递如下：
vm_routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
但是在运行Playbook后，我得到的变量值没有保持缩进。输出如下所示：
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
[{'to': '0.0.0.0/0', 'via': '192.168.0.1'}, {'to': '192.168.0.0/16', 'via': '192.168.0.101'}}
但是我需要输出正确缩进的结果，期望的输出如下：
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
有人可以帮助我如何以正确的缩进格式获取Jinja变量的值吗？提前感谢。
我尝试使用Jinja模板的过滤器，如"to_yaml"和"to_nice_yaml"，但仍然存在相同的缩进问题。
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
{{ vm_routes | to_yaml }}
输出如下所示：
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
- {to: 0.0.0.0/0, via: 192.168.0.1}
- {to: 192.168.0.0/16, via: 192.168.0.101}

I have an template in ansible role that uses variable and the variables are defined in vars.yaml
the template looks like:
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
{{ vm_routes }}
the variable for vm_routes are passed as below in vars.yaml
vm_routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
but after running the playbook i am getting the values for variable without maintaining indentation. the output looks like below
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
[{'to': '0.0.0.0/0', 'via': '192.168.0.1'}, {'to': '192.168.0.0/16', 'via': '192.168.0.101'}}
But i need the output to be correctly indented, the expected output is
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
Can anyone help me how to get the values for jinga variables in the correct format with proper indentation. Thanks in advance
I tried using jinga filters for templates such as "to_yaml" and "to_nice_yaml" , but left out with same indentation problem
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
{{ vm_routes | to_yaml }}
output looks like
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses: [{{ vm_static_ip }}]
nameservers:
addresses: [{{ vm_dns_servers }}]
routes:
- {to: 0.0.0.0/0, via: 192.168.0.1}
- {to: 192.168.0.0/16, via: 192.168.0.101}

给定用于测试的变量
```yaml
vm_guest_interface: eth0
vm_static_ip:
- 10.2.0.11
vm_dns_servers:
- 10.2.0.10
vm_routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
使用 Jinja 过滤器 indent 对整个结构进行缩进。在需要时还可以使用函数 to_nice_yaml 设置结构内部的缩进。例如，模板
- debug:
msg: |
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses:
{{ vm_static_ip|to_nice_yaml|indent(8) }}
nameservers:
addresses:
{{ vm_dns_servers|to_nice_yaml|indent(10) }}
routes:
{{ vm_routes|to_nice_yaml(indent=2)|indent(8) }}
得到
network:
version: 2
ethernets:
eth0:
dhcp4: no
addresses:
- 10.2.0.11
nameservers:
addresses:
- 10.2.0.10
routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
无法消除由函数 to_nice_yaml 创建的新行，我认为。

Given the variables for testing
```yaml
vm_guest_interface: eth0
vm_static_ip:
- 10.2.0.11
vm_dns_servers:
- 10.2.0.10
vm_routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
Use Jinja filter indent to indent the whole structure. Set also the indentation inside the structure by the function to_nice_yaml when needed. For example, the template
- debug:
msg: |
network:
version: 2
ethernets:
{{ vm_guest_interface }}:
dhcp4: no
addresses:
{{ vm_static_ip|to_nice_yaml|indent(8) }}
nameservers:
addresses:
{{ vm_dns_servers|to_nice_yaml|indent(10) }}
routes:
{{ vm_routes|to_nice_yaml(indent=2)|indent(8) }}
gives
network:
version: 2
ethernets:
eth0:
dhcp4: no
addresses:
- 10.2.0.11
nameservers:
addresses:
- 10.2.0.10
routes:
- to: 0.0.0.0/0
via: 192.168.0.1
- to: 192.168.0.0/16
via: 192.168.0.101
It's not possible to get rid of the new lines created by the function to_nice_yaml, I think.
