mysql-如何在VDS上运行docker(lxd /容器)

我有像lxd / container这样的VDS(我看到它是df -h).操作系统已安装debian 7.11.核心：

uname -r
4.13.0-19-generic

我想在安装到VDS中的docker中运行mysql.我拉mysql：

docker images
mysql/mysql-server   5.5      5eb4590ee5eb     8 days ago      180MB

但是当我尝试从根目录运行时,我排除了错误

# docker run --privileged --name=mysql2 -d mysql/mysql-server:5.5
a2f7cd827f0d7f2993bcb3c877fd53ae14727d7bf840d768bb2f0b5fc2e0df97
docker: Error response from daemon: OCI runtime create failed: container_linux.go:296: starting container process caused "process_linux.go:398: container init caused \"rootfs_linux.go:58: mounting \\\"proc\\\" to rootfs \\\"/var/lib/docker/vfs/dir/52c9680a80799cb05d6d423b329cd15486882b7e196dcbd435084287f0d823bf\\\" at \\\"/proc\\\" caused \\\"permission denied\\\"\"": unknown.

当我安装docker时,我除了警告mount：权限被拒绝,但安装了docker.
运行docker时收到警告

service docker start
mount: permission denied
mount: permission denied
mount: permission denied
mount: permission denied
[....] Starting Docker: docker

但是服务正在运行

service docker status
[ ok ] Docker is running.

我没有看到syslog,我的目录/ var / log是

-rw-r--r-- 1 root  root      12438 Jan 24 08:19 alternatives.log

在docker.log中

你能帮我吗？

解决方法:

为了在LXD容器中运行Docker,您需要启用容器嵌套.嵌套意味着一个容器(来自LXD)中可以有一个容器(Docker).

这样启动容器,

lxc launch ubuntu:x mydockers -c security.nesting=true

如果已经创建了LXD容器,则使用

lxc config set mydockers security.nesting true
lxc restart mydockers
