Usage:
|
|
pos vbox create <name> [image] [--dir <path>]
|
|
pos vbox enter <name>
|
|
pos vbox stop <name>
|
|
pos vbox start <name>
|
|
pos vbox rm <name>
|
|
pos vbox ls
|
|
|
|
Manage disposable Docker containers as lightweight VMs.
|
|
|
|
Each container gets a bind-mounted host directory so files persist
|
|
on the host even after the container is removed.
|
|
|
|
Options:
|
|
--dir <path> Use custom directory instead of default ~/<name>
|
|
Use "." for current directory
|
|
|
|
Examples:
|
|
pos vbox create lab1
|
|
pos vbox create lab1 --dir .
|
|
pos vbox create lab1 --dir /mnt/data/lab1
|
|
pos vbox create kali kalilinux/kali-rolling
|
|
pos vbox enter lab1
|
|
pos vbox stop lab1
|
|
pos vbox start lab1
|
|
pos vbox rm lab1
|
|
pos vbox ls
