In Kapitel 1 hast du mehr über Trino und seine Einsatzmöglichkeiten erfahren. Jetzt bist du bereit, es auszuprobieren. In diesem Kapitel lernst du, wie du Trino installierst, eine Datenquelle konfigurierst und die Daten abfragst.
Trino mit dem Docker Container ausprobieren
Das Trino-Projekt stellt einen Docker-Container zur Verfügung. Damit kannst du ganz einfach eine konfigurierte Demo-Umgebung von Trino starten, um einen ersten Einblick zu bekommen und zu erkunden.
Um Trino in Docker auszuführen, musst du Docker auf deinem Rechner installiert haben. Du kannst Docker von der Docker-Website herunterladen oder das Paketsystem deines Betriebssystems verwenden.

docker run -d -p 8080:8080 --name trino-trial trinodb/trino
Verbinden wir uns nun mit dem Container und führen die Trino-Befehlszeilenschnittstelle (CLI) trino auf ihm aus. Sie verbindet sich mit dem Trino-Server, der im selben Container läuft. In der Eingabeaufforderung führst du dann eine Abfrage auf eine Tabelle mit den tpchBenchmark-Daten aus:
$ dockerexec-it trino-trial trino trino>selectcount(*)from tpch.sf1.nation ...
