Script for Testing-Farm

Yesterday evening somebody desperately fought in despair with Packer, the younger sister of Vagrant. The goal was to create a testing farm of n machines for Virtualbox and make them accessible via SSH for further automated software testing/rollout. For me, this is much easier by using a simple bashscript. This morning I’ve made one even before the very first cup of coffee. #!/bin/bash # Pfad zur Master .ova Datei MASTER_OVA="$HOME/projects/testingfarm/DebianBuster.ova" # Anzahl der gewünschten VMs AMOUNT=2 # Name der VMs (Index und Datum werden noch angefügt = NAME-n-YYYYMMDD) PREF_VMNAME="debian" # Anzahl der CPUs PREF_CPU=1 # Zugewiesener Speicher PREF_MEMORY=1024 # Datums-Suffix THE_DATE=$(date +%Y%m%d) # Logdatei zum prüfen THE_LOG="$HOME/projects/testingfarm/$THE_DATE-$PREF_VMNAME.log" # -- Bitte ab hier nichts mehr manuell anpassen -- echo "Beginne Erstellen der Testumgebung... (Start: $(date +%T))" > $THE_LOG for ((i=1; i<= $AMOUNT; i++)) do vboxmanage controlvm $PREF_VMNAME-$i-$THE_DATE poweroff >> $THE_LOG vboxmanage unregistervm $PREF_VMNAME-$i-$THE_DATE --delete >> $THE_LOG vboxmanage import $MASTER_OVA --vsys 0 --cpus $PREF_CPU --memory $PREF_MEMORY --vmname $PREF_VMNAME-$i-$THE_DATE >> $THE_LOG vboxmanage startvm $PREF_VMNAME-$i-$THE_DATE --type headless >> $THE_LOG done echo "...fertig! (Ende: $(date +%T))" >> $THE_LOG The script creates n boxes based on its .ova MASTER. I assume that all network settings (if bridged, NAT or anything else) are specified there. Alongside with a transferred SSH-ID for Ansible, if necessary. The whole setup can of course be done without a master by using createvm inside the for-loop, your mileage may vary. Read more
