首先查看一下目前空間大小

/Applications/Docker.app/Contents/MacOS/qemu-img info ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2

接著調整大小

/Applications/Docker.app/Contents/MacOS/qemu-img resize ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2 +20G

調整後,需重新啟動docker
