Is a Docker container a sandbox?
In general, traditional containers such as LXC or Docker are not considered truly sandboxed as containers on the same host share the same kernel. It is thus not surprising to see container escape vulnerabilities.

How are LXC containers used in sandboxing?
LXC (LinuX Containers) is a OS-level virtualization technology that allows creation and running of multiple isolated Linux virtual environments (VE) on a single control host. These isolation levels or containers can be used to either sandbox specific applications, or to emulate an entirely new host.
Are there any containers that are truly sandboxed?
Traditional containers such as Docker, Linux Containers (LXC), and Rocket (rkt) are not truly sandboxed as they share the host OS kernel. They are resource-efficient, but the attack surface and the potential impact of a breach are still large, especially in a multi-tenant cloud environment that co-locate containers belonging to different customers.
Can you use LXC as a container in Linux?
If you learn about lxc, you can integrate generic Linux containers into your own system design to solve whatever problem you think a container can solve. If it’s not already installed, you can install lxc with your package manager: Containers aren’t actual physical containers, of course, they’re just namespaces.
Can you install LXC with a package manager?
If it’s not already installed, you can install lxc with your package manager: Containers aren’t actual physical containers, of course, they’re just namespaces. Namespaces are meant to limit what a process “trapped” inside of a container are able to do on a system (specifically, it should only be able to do what its parent container specifies).
