我有类似 lxd/container 的 VDS(我看到它是 df -h)。 os安装的是debian 7.11。内核:
uname -r
4.13.0-19-generic
我想在安装到 VDS 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 root 运行时我排除了错误
# docker run --privileged --name=mysql2 -d mysql/mysql-server:5.5
a2f7cd827f0d7f2993bcb3c877fd53ae14727d7bf840d768bb2f0b5fc2e0df97

当我安装 docker 时，我排除了警告 mount: permission denied，但安装了 docker。 当我运行 docker 时，我收到警告
service docker start
mount: permission denied
mount: permission denied
mount: permission denied
mount: permission denied
[....] Starting Docker: docker
但服务正在运行
service docker status
[ ok ] Docker is running.
我没有看到系统日志，我的目录/var/log是

你能帮帮我吗？
最佳答案
为了在 LXD 容器中运行 Docker，您需要启用容器嵌套。嵌套是指一个容器(来自LXD)里面可以有一个容器(docker)。
像这样启动容器，
lxc launch ubuntu:x mydockers -c security.nesting=true
如果 LXD 容器已经创建，则添加标志
lxc config set mydockers security.nesting true
lxc restart mydockers
