Part1. ch01. 06 minikube 설치 후 쿠버네티스 클러스터 구성 시 오류

[jin07150]

안녕하세요.

Windows OS에 VirtualBox 설치하고 Ubuntu 구동하고 있습니다.
minikube까지 설치 되었고, "minikube start --driver docker" 실행시 아래와 같이 오류 발생 합니다.

해결책을 찾은 거 같습니다.
제가 사용하는 internet 망이 proxy 설정을 해야하는데,
docker 구동시 proxy를 사용하도록 설정한 뒤에 오류 없이 진행 됩니다.

$ sudo vi /etc/systemd/system/docker.service.d/proxy.conf

내용 : proxy는 저의 상황에 맞게 수정했습니다.
[Service]
Environment="HTTP_PROXY=http://xx.xx.xx.xx:xxxx"
Environment="HTTPS_PROXY=http://xx.xx.xx.xx:xxxx"

docker 서비를 재실행 했습니다.
$ sudo systemctl restart docker

이후에 'minikube start --driver docker' 실행시 오류 없었습니다.
