재부팅 후 docker ps 안될때

너무 빡쳐서 쓰는 후기 ㅎㅎㅎ

https://stackoverflow.com/questions/33562109/docker-command-cant-connect-to-docker-daemon

sudo usermod -aG docker $(whoami)
docker logout
docker login
docker ps
됨!!!!!!!!!!

1. Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

systemctl docker status => 안됨
sudo service docker status => 안됨

/etc/docker/daemon.json => 안됨
{
"default-address-pools": [
{
"base": "192.168.0.0/16",
"size": 24
}
]
}

2. System has not been booted with systemd as init system (PID 1). Can't operate.

sudo docker run -it -d --privileged=true --name=server server:1.0 /sbin/init => 안됨

sudo dockerd => 이 명령어는 먹는데 docker ps 안됨
sudo usermod -aG docker your-user => 안됨 ( 여기서 방법을 변경하니까 됐다. )
