Overview

This Docker Compose project sets up a Nextcloud application with a PostgreSQL database backend. It utilizes Docker secrets for secure handling of sensitive information like database credentials and Nextcloud admin details.

Prerequisites

Docker and Docker Compose installed
Basic knowledge of Docker and containerization concepts

Services

PostgreSQL Database (db)

Image: postgres
Restart Policy: Always
Volumes: Persistent storage for PostgreSQL data
Environment Variables: Configurations are set via Docker secrets
Secrets: postgres_db, postgres_password, postgres_user

Nextcloud Application (app)

Image: nextcloud
Restart Policy: Always
Ports: 8080 (mapped to internal port 80)
Volumes: Persistent storage for Nextcloud data
Environment Variables: Database and admin configurations set via Docker secrets
Dependencies: Depends on db service
Secrets: nextcloud_admin_password, nextcloud_admin_user, postgres_db, postgres_password, postgres_user

Volumes

db: Volume for PostgreSQL data
nextcloud: Volume for Nextcloud data

Secrets

nextcloud_admin_password: File containing Nextcloud admin password
nextcloud_admin_user: File containing Nextcloud admin username
postgres_db: File containing PostgreSQL database name
postgres_password: File containing PostgreSQL password
postgres_user: File containing PostgreSQL username

Setting Up Secrets

Create the following text files with the respective secret data:

nextcloud_admin_password.txt
nextcloud_admin_user.txt
postgres_db.txt
postgres_password.txt
postgres_user.txt

Deployment

Ensure all secret files are created as specified.
Run docker-compose up -d to start the services in detached mode.

Accessing Nextcloud

After deployment, access Nextcloud at http://<your-ip>:8080
Log in with the Nextcloud admin credentials you set in the secrets.
