【问题描述】:
我在 Mac 上以 root 用户身份登录的 Ubuntu 和 Ubuntu 的 vagrant 虚拟框中运行 docker,我试图从 devicemapper 切换到 overlay,但我收到一条错误消息:
root@vagrant-ubuntu-trusty-64:/# service docker stop
docker stop/waiting
root@vagrant-ubuntu-trusty-64:/# rm -rf /var/lib/docker
root@vagrant-ubuntu-trusty-64:/# docker daemon -s overlay
Command "daemon" is deprecated, and will be removed in Docker 1.16. Please run `dockerd` directly.
INFO[0000] libcontainerd: new containerd process, pid: 6788
WARN[0000] containerd: low RLIMIT_NOFILE changing to max current=1024 max=4096
ERRO[0001] 'overlay' not found as a supported filesystem on this host. Please ensure kernel is new enough and has overlay support loaded.
Error starting daemon: error initializing graphdriver: driver not supported
root@vagrant-ubuntu-trusty-64:/#
我尝试了以下说明:
http://www.projectatomic.io/blog/2015/06/notes-on-fedora-centos-and-docker-storage-drivers/ Unable to start Docker Service in Ubuntu 16.04
但它们都不适合我。
当我尝试遵循以下文档时:
https://docs.docker.com/engine/userguide/storagedriver/overlayfs-driver/
我在第 2 步卡住了,因为 grep 没有从 lsmod 返回任何“覆盖”:
root@vagrant-ubuntu-trusty-64:/# uname -r
3.13.0-107-generic
root@vagrant-ubuntu-trusty-64:/# lsmod | grep overlay
root@vagrant-ubuntu-trusty-64:/#
root@vagrant-ubuntu-trusty-64:/# dockerd --storage-driver=overlay
INFO[0000] libcontainerd: new containerd process, pid: 6816

我该如何解决这个问题?
