Arbeiten im Kurs

Alle eigenen Dateien, Übungen und Experimente bitte in workspace/ ablegen — das Verzeichnis ist gitignored, deine Änderungen stören den git status nicht und du kannst jederzeit git pull machen ohne Konflikte.

Day 2 — Building and Running the App

cd listings/visitcounter

# Build the image
podman build -t visitcounter:latest app/

# Start the full stack
podman compose up -d

# Check it's running
curl localhost:8080

Prerequisites

• Podman installed (podman --version)
• podman-compose installed (podman compose version)
• Go is not required — it compiles inside the container
