mac苹果电脑docker: No space left on device
首先检查一下有没有用不到的镜像，docker images 可以进行rmi，但一般都还有用。
第一步，查看docker挂载的空间
[root@localhost ~]# df -h
文件系统 容量 已用 可用 已用% 挂载点
devtmpfs 716M 0 716M 0% /dev
tmpfs 730M 0 730M 0% /dev/shm
tmpfs 730M 8.7M 721M 2% /run
tmpfs 730M 0 730M 0% /sys/fs/cgroup
/dev/mapper/cl_fedora-root 5.6G 5.3G 320M 95% /
/dev/nvme0n1p2 1014M 155M 860M 16% /boot
/dev/nvme0n1p1 599M 9.0M 590M 2% /boot/efi
tmpfs 146M 0 146M 0% /run/user/0
overlay 5.6G 5.3G 320M 95% /var/lib/docker/overlay2/9a7010dfbe78c01d98031d78a28ff79cb3aa2898c6c394cba038772ad91f15d0/merged
可以看到我的挂载空间是5.6G，很小，其实就是/dev/mapper/cl_fedora-root，然后为了保存我们原来的镜像，现在要进行扩容
第二步，关机，进行硬盘扩容处理。
这个点击虚拟机，选择设置，点击硬盘，修改大小即可。
第三步，systemctl stop docker
第四步，分区查看
[root@localhost /]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 64G 0 disk
├─nvme0n1p3 259:3 0 6.4G 0 part
│ ├─cl_fedora-swap 253:1 0 820M 0 lvm [SWAP]
│ └─cl_fedora-root 253:0 0 5.6G 0 lvm /
├─nvme0n1p1 259:1 0 600M 0 part /boot/efi
└─nvme0n1p2 259:2 0 1G 0 part /boot
sr0 11:0 1 7.6G 0 rom
可以看到新加的磁盘是60G，也就是nvme0n1
第五步之fdisk /dev/nvme0n1。把nvme0n1挂载到/dev/mapper/cl_fedora-root
[root@localhost /]# fdisk /dev/nvme0n1
欢迎使用 fdisk (util-linux 2.23.2)。更改将停留在内存中，直到您决定将更改写入磁盘。
使用写入命令前请三思。命令(输入 m 获取帮助)：n
Partition type:p primary (1 primary, 0 extended, 3 free)e extended
Select (default p): p
分区号 (2-4，默认 2)：4
起始 扇区 (16777216-134217727，默认为 16777216)：

Last 扇区, +扇区 or +size{K,M,G} (16777216-134217727，默认为 134217727)：
将使用默认值 134217727
分区 4 已设置为 Linux 类型，大小设为 56 GiB命令(输入 m 获取帮助)：p磁盘 /dev/nvme0n1：68.7 GB, 68719476736 字节，134217728 个扇区

The partition table has been altered!Calling ioctl() to re-read partition table.
正在同步磁盘。
第六步之parted /dev/nvme0n1。把nvme0n1挂到/dev/mapper/cl_fedora-root，注意需要计算挂载大小
[root@localhost /]# parted /dev/nvme0n1
GNU Parted 3.1
使用 /dev/nvme0n1
