• App: Diese Service-Definition enthält die Laravel-Anwendung und startet das personalisierte Docker-Image digitalocean.com/php. Außerdem wird der Parameter working_dir im Container auf / var / www gesetzt.
• Webserver: Diese Dienstdefinition übernimmt das nginx: alpine-Image von Docker und öffnet die Ports 80 und 443.
• db: Diese Dienstdefinition ruft das mysql: 5.7.22-Image von Docker ab und definiert neue Umgebungsvariablen, einschließlich der Laravel-Datenbank für Ihre Anwendung und des Root-Kennworts für die Datenbank. Sie können einen beliebigen Datenbanknamen verwenden. Sie sollten auch Ihr_mysql_root_password durch Ihr eigenes sicheres Passwort ersetzen. Diese Dienstdefinition ordnet auch den Host-Port 3306 dem Container-Port 3306 zu.
