Netplan 抱怨“未知的关键桥梁”

Question

我正在尝试为 KVM 设置网桥，但我不断收到错误消息

网络定义错误 //etc/netplan/50-cloud-init.yaml line 5 column 0: unknown key bridges.

有趣的是，第 5 行第 0 列是network，而不是bridges，所以我不确定为什么要说桥梁。这是.yaml我正在尝试的：

# This file is generated from information provided by
# the datasource. Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
  version: 2
  renderer: networkd
  ethernets:
    enp2s0:
      dhcp4: no
bridges:
    br0:
      interfaces: [enp2s0]
      dhcp4: no
      addresses: [192.168.1.3/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [192.168.1.1]

Answer 1

Yaml 文件对正确缩进非常挑剔。在 bridges 关键字之前放置两个空格键，错误消息应该会消失。
