enlarge docker space

問題：Your Docker build environment ran out of disk space.

# 檢查 docker 狀態

df -h
docker system df

# 清理docker 空間

# Remove all unused data
docker system prune -a --volumes

# Remove build cache
docker builder prune -a

# Check again
df -h

問題：變更docker 位置

# Stop Docker
sudo systemctl stop docker

# Edit Docker config
sudo nano /etc/docker/daemon.json

# add the following code in daemon.json

{
  "data-root": "/new/docker/path"
}

# Create new directory
sudo mkdir -p /new/docker/path

# Move existing data (optional)
sudo rsync -aP /var/lib/docker/ /new/docker/path/

# Start Docker
sudo systemctl start docker
