Benefits¶

Why use DataSci Homelab instead of running RStudio or Jupyter locally?

The Case for Containerization¶

Your Main Machine Stays Clean¶

Every data science package brings dependencies. Over time, your laptop accumulates:

With containers: Your host system remains pristine. Uninstall Docker, and it's like the environment never existed.

Setup Time¶

Reproducibility¶

Recovery from Disasters¶

Specific Advantages¶

1. Multi-Architecture Without Pain¶

Local Reality:
- macOS on M1: "This package doesn't have ARM binaries"
- Windows: "Install Rtools, pray to the gods"
- Linux: "Which distro? Which version?"

DataSci Homelab:
- Pull image
- Works

2. Remote Access Built-In¶

RStudio Desktop and JupyterLab are local applications. To access remotely, you need to:

• Set up SSH tunneling
• Configure port forwarding
• Deal with firewall issues
• Hope your laptop doesn't sleep

DataSci Homelab gives you:

• Web interfaces by default
• Works from any device with a browser
• Cloudflare Tunnel integration documented
• Access from your phone if needed

3. Package Persistence Done Right¶

4. True Isolation¶

# Scenario: Testing a new package

# Local approach:
# "Will installing this break my other projects?"
# "Let me create another conda env..."
# "Wait, which env am I in?"

# Container approach:
install.packages("experimental_package")
# If it breaks things: docker-compose down && up
# Your volumes (packages) persist, system resets

5. Consistent Development → Production Path¶

When Local Installation Is Better¶

Be honest about trade-offs:

Choose Local When:¶

• You need GPU access — Container GPU passthrough is complex
• You're doing only one thing — Just R? Just Python? Local may be simpler
• You have limited disk space — Docker image is ~8GB
• You're learning — Understanding local installation teaches fundamentals
• You need native performance — Containers have minimal overhead, but it exists

Choose DataSci Homelab When:¶

• You work with both R and Python
• You value reproducibility
• You collaborate with others
• You want remote access
• You're tired of debugging environments
• You deploy to servers

Real-World Scenarios¶

Scenario 1: macOS Update¶

Local:

1. macOS updates
2. Xcode command line tools break
3. R packages need recompilation
4. Some packages fail mysteriously
5. 4 hours later, mostly working

Container:

1. macOS updates
2. Docker still works
3. docker-compose up
4. Done

Scenario 2: New Team Member¶

Local:

1. "Here's our setup doc" (outdated)
2. Install R, specific version
3. Install RStudio
4. Install packages (30 minutes)
5. Fix the three that failed
6. Configure settings
7. Set up Git credentials
8. "Why doesn't this work on my machine?"

Container:

1. git clone
2. ./scripts/setup.sh
3. docker-compose up
4. "Welcome to the team"

Scenario 3: Switching Projects¶

Local:

1. Activate correct conda env
2. Wait, which R version does this need?
3. Switch renv
4. Reinstall packages
5. Fix conflicts

Container:

1. cd project-folder
2. docker-compose up
3. Work

Performance Comparison¶

The overhead is negligible for data science workloads.

Cost-Benefit Summary¶

Costs¶

• Docker installation (~500MB)
• Image download (~8GB)
• Learning basic Docker commands
• Slight memory overhead

Benefits¶

• Zero environment conflicts
• Reproducible across machines
• Built-in remote access
• Quick disaster recovery
• Easy onboarding
• Clean host system
• Professional workflow

The Bottom Line¶

If you've ever spent an afternoon debugging why a package won't install, DataSci Homelab pays for itself in the first week.

The containerized approach trades a small upfront learning curve for:

• Hours saved on environment issues
• Confidence in reproducibility
• Freedom from "works on my machine"
• Professional-grade setup without the complexity
