To run the Docker daemon as a fully privileged service, but granting non-root WARNING: Access to the remote API on a privileged Docker daemon is equivalent ================================================================================ |

해당 error는 docker를 root권한으로 사용하려 했을 경우 나옵니다. 따라서 전용 사용자 계정을 추가로 생성해줘야 합니다. |
minikube v1.32.0 on Ubuntu 22.04 (kvm/amd64)
Automatically selected the docker driver. Other choices: none, ssh
The “docker” driver should not be used with root privileges. If you wish to continue as root, use –force.
If you are running minikube within a VM, consider using –driver=none:
https://minikube.sigs.k8s.io/docs/reference/drivers/none/
Exiting due to DRV_AS_ROOT: The “docker” driver should not be used with root privileges.
사용자 계정 생성
useradd -m -d /home/smileserv -s /bin/bash smileserv // /home/smilserv가 home 디렉터리인 smileserv 사용자 생성
passwd smileserv // smileserv 비밀번호 설정
usermod -aG sudo smileserv // smileserv 계정 sudo 권한
usermod -aG docker smileserv // smileserv 계정 docker 권한
su smileserv
