Jetson AGX docker floder moving

 Jetson AGX 用一個小小的 32GB EMMC 放 OS, 就用了 55%

隨便弄個幾 GB docker image, 就很緊張, 這邊嘗試將一些檔案搬到 USB flash,

 # stop docker

sudo docker rm -f $(docker ps -aq); docker rmi -f $(docker images -q)
sudo systemctl stop docker

# backup docker
sudo tar -zcC /var/lib docker > /home/nvidia/usb500gb/var_lib_docker-backup-$(date +%s).tar.gz

# assume ~/usb500gb is external USB flash

# symbol link
sudo rm -rf /var/lib/docker/image
sudo rm -rf /var/lib/docker/containers
sudo ln -s /home/nvidia/usb500gb/docker/image /var/lib/docker/image
sudo ln -s /home/nvidia/usb500gb/docker/containers /var/lib/docker/containers

sudo systemctl start docker
