Dev Environment (Docker)

Prerequisites

• Docker + Docker Compose installed on your server

Setup

# 1. Clone / copy the project
cd /opt
git clone ... diskwatch   # or scp from your machine
cd diskwatch

# 2. Make the launcher executable
chmod +x dev.sh

# 3. Build the image (~1 minute)
./dev.sh build

# 4. Enter the dev shell
./dev.sh run
# You are now inside the container ↓

# 5. Run DiskWatch
python diskwatch.py

Live editing

The ./app/ folder is mounted into the container at /app.
Edit diskwatch.py on your host with any editor, and re-run python diskwatch.py inside the container — no rebuild needed.

Run without entering the shell

./dev.sh watch

---

Install directly on the server (no Docker)

# Python 3.10+ required
pip install textual psutil rich

# Run
python /path/to/diskwatch.py

To make it available as a command:

sudo cp app/diskwatch.py /usr/local/bin/diskwatch
sudo chmod +x /usr/local/bin/diskwatch

# Then just type:
diskwatch
