[Docker] 설치에러 - Cannot process diagnostics. Reason: Error invoking remote method 'desktop-go-backend'

Docker Desktop Window를 처음 설치할 때 발견할 수 있는 오류이다. 

설치하고나서 setting이 무한로딩 되거나 started.. 문구만 뜨고 아무런 진행이 안되는 경우에 해당한다. 기본적인 설치를 살펴봤어야 했는데 너무 돌고돌아 원인을 찾았다. (외국 사이트에 별의별 방법들을 따라하다가..)

에러에서도 보면 알 수 있듯이, backend가 제대로 설치되지 않은 경우인데, WSL 2 설정이 제대로 되어 있지 않은 경우에 발생했다.

 

설치시, WSL 2를 활성화하고 Linux용 Windows 하위 시스템을 활성화하고 가상머신 기능을 활성화, Linux 커널패키지 다운로드 등 리눅스를 윈도우 환경에서 실행할 수 있도록 세팅해야 한다.

 

Powershell 활성화 명령어

// Linux용 Windows 하위 시스템을 활성화
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

// 가상머신 기능을 활성화
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

// WSL2를 기본 버전으로 설정
wsl --set-default-version 2

 

Windows에서 Linux 실행하기

 

Microsoft에서 리눅스 배포를 선택하는데 Ubuntu가 없어서 나는 Debian을 설치했는데, 왜 없어졌는지는 모르겠다. 이후에 Powershell에서 제대로 설치됐는지 확인할 수 있었다.
