Cannot connect to the Docker daemon at unix:///var/run/docker.sock

docker 명령어 실행시에 다음과 같이 docker의 설치파일 충돌로 Cannot connect to the Docker daemon 문제가 발생했다.

% docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=1234 --name mysql mysql 

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.

나의 케이스의 경우 이전에 docker를 home brew로 설치하지 않아, brew연결이 되어있지 않았기 때문에 기존 docker를 삭제하고 재설치 하는 방법을 선택했다.

# docker가 연결되어 있지 않음 확인 
% brew link docker
Error: No such keg: /usr/local/Cellar/docker

# 기존 docker 위치 확인 
% which node
/Users/user/.nvm/versions/node/v16.1.0/bin/node
% which docker
/usr/local/bin/docker

# 기존 docker 삭제 
% sudo rm -rf /usr/local/bin/docker

# brew로 docker 재설치 
% brew install --cask docker
