-Lieber Iljas,
-
-Dein Weihnachtsgeschenk dieses Jahr ist mit Arbeit verbunden - Arbeit
-Deinerseits wohlgemerkt ;-)
-
-Um es zu genießen mußt Du zuerst:
-- dem mächtigen amazon Konzern noch weiter in die Hände spielen und Dir
-einen aws Account einrichten
-- auf Deinem nagelneuen AWS Account unter Sicherheit/IAM einen Benutzer
-hinzufügen mit Zugriffstyp "Programmgesteuerter Zugriff"
-- die dabei generierten Tokens Dir merken und z.B. in Deine .bashrc
-eintragen als Umgebungsvariablen `AWS_ACCESS_KEY_ID` und `AWS_SECRET_ACCESS_KEY`
-- Dir ansible installieren - und da Du wahrscheinlich verstehen willst was
-passiert, ist das ansible lernen die eigentliche Arbeit ;-)
-- das ansible-Playbook anschauen und ausführen, dass Stefan erstellt hat und
-das unter wg-aws geclont ist
-- Dir auf Deinen Geräten wireguard als VPN Software installieren
-- die Konfigurationen, die das ansible Playbook erstellt hat auf Deinen
-Geräten importieren (als Datei oder qrcode)
-- Dich über Deinen neuen mini-Cloud-VPN-Server freuen auf dem Du auch sonst
-alles machen kannst was Du magst
-- mit der Inbetriebnahme den unten stehenden Gutschein bei uns einlösen
-;-) - leider bietet aws nämlich kein Prepaid an ...
