Runtime directory and storage driver

You may want to control the disk space used for Docker images, containers, and volumes by moving it to a separate partition.

To accomplish this, set the following flags in the daemon.json file:

{
    "data-root": "/mnt/docker-data",
    "storage-driver": "overlay"
}

/etc/systemd/system/multi-user.target.wants/

cp docker.service /home

vi dockefr.service

systemd -> cgroupfs 로 바꾸로 싶따면

--exec-opt native.cgroupdriver=systemd  해당 부분에서 systtemd를 cgroupfs로 변경하면 됨

systemctl daemon-reload

systemctl restart docker

 여러 에러가 나면서

Command /root/.virtualenvs/r-tensorflow/bin/python - setuptools pkg_resources pip wheel failed

요런 에러가 나면

pip install --upgrade virtualenv

sudo virtualenv .env   <= 요건 안해도 되던데...

해당 부분은 ip 등록 부분이 빠져서 생긴 문제임

sudo apt update
sudo apt install python3-pip
sudo pip3 install -vU setuptools

이렇게 하던가 아니면 해당 이미지를 pull로 받아서 각 node에 docker load < 해주면 된다
