Docker<\/a> ist schnell installiert, einfach nach der Aktuallisierung des Systems folgenden Befehl eingeben:<\/p>\n

\r\ncurl -sSL https:\/\/get.docker.com | sh\r\n<\/pre>\n
Nun wollen wir den Docker-Kontainer mal schnell testen, in dem wir ein Alpinelinux<\/a> laden und in einer Shell starten, da es nur ein paar MB sind, die geladen werden m\u00fcssen:<\/p>\n
sudo docker run -ti alpine:latest \/bin\/sh<\/pre>\n
Dann schauen wir doch mal, ob das Alpinelinux l\u00e4uft:<\/p>\n
\"\"<\/p>\n
Ok, es l\u00e4uft.<\/p>\n
Dann mal ein Prometheus<\/a> Server laufen lassen:<\/p>\n
sudo docker run –detach –name hello-world-prometheus –publish 8000:8080 infrastructureascode\/hello-world<\/p>\n
Abfrage dann mit:<\/p>\n
curl http:\/\/0.0.0.0:8000\/metrics<\/p>\n
Ergebnis:<\/p>\n
