Nextcloud mit Podman - ziemlich einfach#
Quelle: https://www.linux-community.de/ausgaben/linuxuser/2022/06/nextcloud-mit-podman-aufsetzen/
Alle Angaben ohne Gewähr. Bei mir läuft das Nextcloud-Geraffel momentan.
Nach der erstmaligen Installation brauche ich bei den nächsten Rechnerneustarts nur das letzte Skript,
~/src/sh/podman-nextcloud/nextcloud-podman-start.sh, aufzurufen, damit Nextcloud im Container wieder gestartet wird.
Nextcloud lauscht dann auf http(s)://<HOSTNAMEN HIER EINSETZEN>:8080, Podman-Cockpit auf http...:9090.
Für podman-cockpit muss der Systemd-Dienst cockpit laufen, z.B. so:
sudo systemctl start cockpit

# Das Paket "cockpit-podman" installiert als Abhängigkeit "podman" per arch-pacman gleich mit.
