Docker

You'll use linux-specific syscalls in this challenge. so we'll run your code inside a Docker container.

Please ensure you have Docker installed locally.

Next, add a shell alias:

alias mydocker='docker build -t mydocker . && docker run --cap-add="SYS_ADMIN" mydocker'

(The --cap-add="SYS_ADMIN" flag is required to create PID Namespaces)

You can now execute your program like this:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer echo hey

This command compiles your Rust project, so it might be slow the first time you run it. Subsequent runs will be fast.
