GraalVM

Cette image est directement compatible avec l’outil Pterodactyl.

Introduction

Il est nécessaire d’avoir installé au préalable Docker sur votre Archlinux.

Pour construire une image Docker compatible AMD64 vous aurez besoin de 8 fichiers :

• build.sh
• platform.sh
• Dockerfile
• bashrc (à placer dans le répertoire files)
• docker-java-home (à placer dans le répertoire files)
• entrypoint.sh (à placer dans le répertoire files)

Fichiers requis

platform.sh

#!/bin/bash

# Used in Docker build to set platform dependent variables

case $TARGETARCH in

    "amd64")
	echo "x86_64-unknown-linux-gnu" > /.platform
	echo "" > /.compiler
	;;
    "arm64")
	echo "aarch64-unknown-linux-gnu" > /.platform

Procédure

Avant de vous lancer dans la procédure, il faut :

• Avoir un compte Oracle (obligatoire)
• Dans votre shell, vous devez vous identifier avec docker login en saisissant vos identifiants de comptes Oracle

Il peut être aussi utile d’ajouter la registry d’Oracle dans la configuration de Portainer par exemple.

Enfin, pour lancer la construction de l’image, il suffit de donner au script shell build.sh les droits d’exécution puis de le lancer :

sudo chmod +x build.sh && sudo bash build.sh

Conclusion

Vous avez maintenant une image Docker compatible AMD64 à lancer sous Docker (ou avec Portainer :p).

NB : Vous pouvez l’utiliser directement sous Pterodactyl à condition d’avoir une Registry Docker sur laquelle vous pouvez déposer l’image pour qu’elle puisse être récupérée par Pterodactyl de la même façon que les images natives.
