使用 Ubuntu 18.04 和 netplan 进行 Rocky 发布

我目前正在使用 Newton 和 ubuntu 16.04，并希望通过 Ubuntu 18.04 迁移到 Rocky。但我发现 Ubuntu 18.04 使用 netplan 而不是 ifupdown 来管理网络资源。我意识到这更像是一个 Openstack 问题，但由于 Openstack 在网络方面需要相当多的复杂性，我认为在这里发布问题更合适。

我有适用于 ubuntu 16.04 的以下接口文件，正在查看有关如何将该设置转换为 netplan 的文档？

有人能帮忙吗？谢谢

这是我当前的 ifupdown 配置

以下是我正在使用的 netplan 配置示例：

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      dhcp6: no
# When using bridging move this block to the bridge definition or it wont work... dont really kno why
#      addresses: [192.168.2.22/24]
#      gateway4: 192.168.2.1
#      nameservers:
#              addresses: [8.8.8.8,8.8.4.4]
  bridges:
    br0:
      addresses: [192.168.2.22/24]
      gateway4: 192.168.2.1
      nameservers:
              addresses: [8.8.8.8,8.8.4.4]
      parameters:
              stp: false
              forward-delay: 0
      interfaces: [eno1]

设置好文件后，您需要应用它：

# netplan apply
