 I was trying to pull docker image from docker hub. But I got denied. I was using GitAction to deploy but failed. Run docker pull ***/***:latest 2 docker pull ***/***:latest 3 shell: /usr/bin/bash -e {0} 4 env: 5 DOCKER_IMAGE: ***/*** 6 permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.46/images/create?fromImage=***%2F***&tag=latest": dial unix /var/run/docker.sock: connect: permission denied 7 Error: Process completed with exit code 1. Connecte to EC2 and write this terminal. sudo chmod 555 /var/run/docker.sock copy Now it works.

 1. docker버전 확인시 아래와 같이 'permission denied'가 된 상태 파일 권한을 666으로 변경하여 다른 사용자도 접근 가능하게 변경한다. $ sudo chmod 666 /var/run/docker.sock copy
