kvm 客户机（Debian 和 Centos）中的 Cloud-init 未设置界面设置

我正在尝试使用 cloud-init 设置 kvm 客户机（目前为 Debian 11 和 CentOS Stream 8），并且正在寻求帮助来更正元数据和用户数据文件。其他一切似乎都正常，但网络接口设置未设置，尽管我确实看到 cloud-init 日志显示它们已设置。请参见下文：

对于 Debian：

请问我做错了什么？

答案1

我的第一个错误似乎是将网络配置添加到。使用单独的网络配置文件（ ）和适用于 debian 和 centos 的 ENI 版本user-data使其正常工作。network-config

对于 Debian：

cat << EOF > $network_config
  version: 1
  config:
    - type: physical
      name: eth0
      subnets:
        - type: static
          address: 10.10.0.26
          gateway: 10.10.0.254
    - type: route
      destination: 10.100.0.0/24
      gateway: 10.10.0.249
    - type: nameserver
      address:
        - 10.100.0.23
        - 10.100.0.17
        - 10.100.0.18
      search:
        - testing.mydom
        - production.mydom
        - admin.mydom
EOF

对于 centos：

cat << EOF > $network_config
  version: 1
  config:
    - type: physical
      name: eth0
      subnets:
        - type: static
          address: 10.10.0.26
          gateway: 10.10.0.254
    - type: route
      destination: 10.100.0.0/24
      gateway: 10.10.0.249
    - type: nameserver
      address:
        - 10.100.0.23
        - 10.100.0.17
        - 10.100.0.18
      search:
        - testing.mydom
        - production.mydom
        - admin.mydom
EOF

我们将看看 Ubuntu 镜像发生的情况（并修复包“更新”和安装）。
