Ubuntu 18.04 透過 netplan 設定網路卡 IP

照上面的說明看了一下 /etc/netplan 目錄，查閱一下 /etc/netplan/50-cloud-init.yaml，如下：

# 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:
 ethernets:
 ens192:
 dhcp4: true
 ens224:
 dhcp4: true
 version: 2

看來可以關閉 cloud network，但是我其實也沒有要用 cloud-init，乾脆移除它，如下：

sudo apt-get remove cloud-init

然後把 /etc/netplan/50-cloud-init.yaml 改成下面這樣：

# 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:
 ethernets:
 ens192:
 addresses: [192.168.32.231/24]
 gateway4: 192.168.32.1
 nameservers:
 addresses: [8.8.8.8, 8.8.4.4]
 dhcp4: no
 ens224:
 dhcp4: true
 version: 2

這幾年 yaml 深得大眾的心，設定檔就是要用 yaml 格式才是潮，解說一下上述幾個設定：
