Docker uses the resource isolation features of the Linux kernel such as cgroups and kernel namespaces, and a union-capable file system such as OverlayFS and others to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines (VMs).

Docker 使用了 Linux 内核中的资源隔离特性（如 cgroup 和内核命名空间）以及支持联合文件系统（如 OverlayFS 和其他），允许多个相互独立的“容器”一起运行在同一 Linux 实例上，从而避免启动和维护虚拟机（VMs）的开销。
