Containers & Virtualization

// Sandboxing, local virtual network switching, and server virtualization

> Docker

Primary Purpose

Containerization platform.

Development Advantages

Guarantees reproducible dev, staging, and prod environments. Eliminates local software pollution (like database installs) by spinning up isolated containers.

// Setup & Installation Guide

install_docker.shShell

# Install Docker Engine and Docker Compose on Linux
sudo apt-get update
sudo apt-get install -y docker.io docker-compose-plugin

# Start and enable the Docker daemon
sudo systemctl enable --now docker

# Verify setup
docker --version && docker compose version

Practical Integration & Usage Example

Dockerfile & compose configsYAML / Docker

# Dockerfile for isolated firmware testing build harness
FROM ubuntu:22.04

# Install compilation toolchains and network requirements
RUN apt-get update && apt-get install -y \
    build-essential \
    gcc-multilib \
    iputils-ping \
    python3-pip \
    curl && \
    rm -rf /var/lib/apt/lists/*

> Local Hypervisors

Hyper-V VirtualBox VMware Workstation

Hyper-V

Windows native hypervisor.

Type-1 bare-metal hypervisor integrated in Windows. High-performance host VM management for running automated CI/CD simulation tests locally.

VirtualBox

Cross-platform virtualization.

Allows fast local guest OS virtualization for testing cross-platform compatibility of firmware and utility scripts.

VMware Workstation Pro

Advanced hypervisor for local development.

Provides complex virtual networking configurations, virtual cloning, and robust VM snapshot management to restore clean states instantly.

// Setup & Installation Guide

hyperv_enable.ps1PowerShell

# Enable Hyper-V via PowerShell (Administrator)
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

# Create virtual switch for internal SPS communication
New-VMSwitch -Name "SPS-Internal-Bridge" -SwitchType Internal

# Allocate virtual machine for local execution unit test harness
New-VM -Name "VxWorks-Harness-VM" -MemoryStartupBytes 2GB -Generation 2
