[Docker](Solved) Is the docker daemon running?

docker build를 하려고했더니 아래와 같은 error 발생

Is the docker daemon running?

docker 실행이 안됬나보다 하고 실행 시켜봄

$ systemctl start docker.service 

 

동작 안됨. 아래 커맨드로 좀 더 자세한 원인 파악을 해봄

$ journalctl -xe

 위 error log중에서 주의깊게 볼 부분이 

 4월 16 14:17:01 rusdev dockerd[160332]: unable to configure the Docker daemon with file /etc/docker/daemon.json: invalid character '"' after object key:value pair

이 로그가 조금 수상해보였다. 

 

daemon.json에 key:value 가 안맞는다..? 일단 daemon.json파일을 열어보았다.

daemon.json

{
   "insecure-registries" : [ "10.20.1.52:5000"]
   "insecure-registries" : [ "docker.domain.com"]
}

" , " 가 빠진거같은데..?  

daemon.json 수정 후

{
   "insecure-registries" : [ "10.20.1.52:5000"],
   "insecure-registries" : [ "docker.domain.com"]
}

수정후 정상적으로 docker service 되는것을 확인함
