增加容器大小操作系统（ubuntu 16.04）

我刚刚下载了 ubuntu

docker pull ubuntu:16.04

然后我想在其中安装 mysql 和 nginx，但大小有限

docker run -d -t --name temporary ubuntu:16.04
winpty docker exec -it temporary bash
df -h

我得到了

root@90215dee6bc7:/# df -h
Filesystem      Size  Used Avail Use% Mounted on
overlay         991M  280M  711M  29% /
tmpfs           991M     0  991M   0% /dev
tmpfs           991M     0  991M   0% /sys/fs/cgroup
tmpfs           991M  280M  711M  29% /etc/hosts
shm              64M     0   64M   0% /dev/shm
tmpfs           991M     0  991M   0% /sys/firmware

如何增加该尺寸？

我想要 20GB 大小

如果您只想创建一个容器，那么：

docker create -it --storage-opt size=20G ubuntu:16.04 /bin/bash



如果您想增加存储驱动程序的默认基本大小，那么：

dockerd --storage-opt dm.basesize=20G
  • 确保重新启动docker守护进程 systemctl restart docker，然后您就可以执行之前的拉取和运行。
