Rancher Desktop Setup

Installation

# macOS (Homebrew) brew install --cask rancher # Windows (PowerShell) winget install -e --id suse.RancherDesktop # Linux # Download AppImage from https://rancherdesktop.io/ chmod +x Rancher.Desktop-*.AppImage ./Rancher.Desktop-*.AppImage

Configuration

# rancher-desktop.yaml containerEngine: name: containerd version: v1.6.8 kubernetes: enabled: true version: v1.24.4 virtualMachine: memoryInGB: 4 numberCPUs: 2 portForwarding: includeKubernetesServices: true

Podman Desktop Setup

Installation

# macOS (Homebrew) brew install podman-desktop # Windows (PowerShell) winget install -e --id RedHat.Podman-Desktop # Linux (Fedora) sudo dnf install podman-desktop

Machine Configuration

# Initialize Podman machine podman machine init --cpus 2 --memory 4096 # Start the machine podman machine start # Configure Docker compatibility echo 'alias docker=podman' >> ~/.bashrc source ~/.bashrc

Lima Setup

Installation

# macOS (Homebrew) brew install lima # Create default instance limactl start template://docker # Configure Docker CLI export DOCKER_HOST=unix://$HOME/.lima/docker/sock/docker.sock

VM Configuration

# docker.yaml images: - location: "https://cloud-images.ubuntu.com/releases/22.04/release/ubuntu-22.04-server-cloudimg-amd64.img" arch: "x86_64" digest: "sha256:..." cpus: 2 memory: "4GiB" mounts: - location: "~" writable: true containerd: system: false user: true provision: - mode: system script: | #!/bin/bash apt-get update apt-get install -y docker.io

Development Workflow

Docker Compose Support

# docker-compose.yml (works with all alternatives) version: '3.8' services: web: build: . ports: - "8080:8080" volumes: - .:/app environment: NODE_ENV: development db: image: postgres:14 environment: POSTGRES_PASSWORD: example

Integration Capabilities

IDE Integration

// VS Code settings.json { "docker.host": "unix:///Users/username/.lima/docker/sock/docker.sock", "kubernetes.kubectlPath": "/usr/local/bin/kubectl", "kubernetes.kubeconfig": "/Users/username/.kube/config" }

CI/CD Integration

# GitHub Actions workflow name: Container Build on: [push] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Set up Podman run: | sudo apt-get update sudo apt-get install -y podman - name: Build and push run: | podman build -t myapp:latest . podman push myapp:latest

Migration Guide

Data Migration

# Export Docker Desktop data docker save myapp:latest > myapp.tar # Import to alternative # Rancher Desktop docker load < myapp.tar # Podman podman load < myapp.tar # Lima limactl copy myapp.tar lima-default: docker load < myapp.tar

Best Practices

Tool Selection Guide

  1. Resource Constraints

    function recommendTool(constraints: { memory: number; // GB cpus: number; // cores diskSpace: number; // GB }): string { if (constraints.memory < 4) { return "Lima"; } else if (constraints.memory < 8) { return "Podman Desktop"; } else { return "Rancher Desktop"; } }
  2. Use Case Matching

    function matchUseCase(requirements: { kubernetes: boolean; gui: boolean; dockerCompat: boolean; }): string { if (requirements.kubernetes) { return "Rancher Desktop"; } else if (requirements.gui) { return "Podman Desktop"; } else { return "Lima"; } }
