☕ Java Docker Images for Pterodactyl

Lightweight, multivendor Java Docker images tailored for: Pterodactyl, Pelican panels.

From June 29, 2025, we’re migrating all images to Alpine Linux where possible. Currently migrating: GraalVM and Adoptium

---

🛠️ Features

• JDK and JRE variants
• Multi-version support (Java 8 → 24+)
• Compatible with containerized game and app hosting

---

📦 Vendors

Each vendor has its own folder:

• /Adoptium - README
• /Amazon Corretto - README
• /Azul Zulu - README
• /GraalVM - README
• /OpenJDK - README (DEPRECATED - We will not update this image anymore files of it were removed but GHCR images are still available)

Inside each:

/java-version[-jre]/Dockerfile

---

✅ Why sudden switch to Alpine?

• Smaller image sizes (usually debian based images are around 450-850MB, alpine on other hand from 167-389MB)
• Faster startup and deploys

---

🚀 Usage Example

FROM ghcr.io/vega-network-main/java-docker-images:openjdk-17-jre-alpine
USER container # not always needed
COPY my-app.jar /app.jar
CMD ["java", "-jar", "/app.jar"]
