Nextcloud + PostgreSQL + Redis

Nextcloud is a self-hosted storage and collaboration platform: synced files across devices, calendars, contacts, collaborative document editing, and video calls.

This Stack installs it with PostgreSQL and Redis, which Nextcloud uses for file locking and caching.

Services included

Besides the application, the Stack brings up PostgreSQL, Redis, an nginx that accepts traffic on port 80, an automatic backups service, and the web file manager.

Getting started

Install the Stack and start it:

bash

docker-deploy-stack --stack php/nextcloud-postgres-redis
cd /root/stack/php/nextcloud-postgres-redis
docker compose up -d

This is a ready-to-use application: you don’t need to upload any code. Themes, plugins, extensions and files you upload from its admin panel are stored in the Stack and are included in automatic backups.
