yaml 파일 예시

# This is the network config written by 'subiquity'
network:
  ethernets:
	  eno3:
	    dhcp4: no
	    addresses:
		    - 192.168.100.98/24
	    nameservers:
	      addresses: [8.8.8.8, 8.8.4.4]
	      routes:
		      - to: default
        via: 192.168.200.255
  version: 2
  renderer: NetworkManager
  
또는
  
network:
  ethernets: {}
  version: 2
  renderer: NetworkManager

 

subiquity는 Ubuntu Server Installer이다.

즉, yaml파일이 설치되면서 자동으로 생성된 파일이라는 의미이다.

network ~ renderer가 지워지면 리눅스 네트워크 설정이 비활성화돼서 네트워크가 고장난다.

 

yaml 파일 수정 후

sudo netplan apply 해서 적용한다.
