[Docker] docker.errors.DockerException: Error while fetching server API version: Connection aborted 오류해결

오류 내용

저는 아래와 같은 오류가 발생했습니다.

Traceback (most recent call last):
  File "/usr/bin/docker-compose", line 33, in <module>

오류 원인

결론적으로 저의 경우에는 도커 서버가 구동 중이지 않아서 오류가 발생했습니다.

도커가 구동 중인지 확인하기 위해서 아래 명령어를 실행해보았습니다.

┌──(vagrant㉿kali)-[/mnt/gnuboard5]
└─$ systemctl status docker.service                                                                            130 ⨯

   Main PID: 829 (code=exited, status=0/SUCCESS)
        CPU: 23.339s

Warning: some journal files were not opened due to insufficient permissions.

그랬더니 Active 상태가 inactive 로 구동되지 않고 있음을 확인할 수 있었습니다.

때문에 다시 구동시켜줘보았습니다.

 

오류 해결

┌──(vagrant㉿kali)-[/mnt/gnuboard5]
└─$ sudo systemctl start docker.service

┌──(vagrant㉿kali)-[/mnt/gnuboard5]
└─$ systemctl status docker.service    
● docker.service - Docker Application Container Engine

             └─25620 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

위와 같이 Active 상태가 active (running)이 된 것을 볼 수 있었습니다.

그리고 docker-compose 를 했더니 잘 실행되는 것을 확인했습니다.

 

만약 저와 같이 Kali Linux 칼리 리눅스 환경에서 도커를 설치하시는 분이라면 아래 포스팅을 참고해보세요!

저는 여기서 참고했습니다!
