RPi-Monitor

Introduction

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

Pour construire une image Docker compatible ARM64 pour le Raspberry PI vous aurez besoin de 3 fichiers:

• build.sh
• platform.sh
• Dockerfile
• run.sh (à placer dans un sous-répertoire work)

Fichiers requis

platform.sh

[Fichier]

#!/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
	echo "gcc-aarch64-linux-gnu" > /.compiler

EXPOSE	8888

ADD	work/run.sh /run.sh
RUN	chmod +x /run.sh
CMD	bash -C '/run.sh';'bash'

Procédure

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

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

Conclusion

Vous avez maintenant une image Docker compatible ARM64 à lancer sous Docker (ou avec Portainer :p).
