docker compose up -d - Why build your own?
- Storing large amounts of data on public cloud services can be expensive.
- I wanted to set up my own storage server in a local environment to save costs.
- Why Nextcloud + Docker?
- Ease of Setup: Get up and running quickly.
- Simple Maintenance: Easy to update and manage containers. - OS: Debian Linux
- Prerequisites: A system where Docker and Docker Compose can be installed. - Install Docker - Create a Working Directory - Create `docker-compose.yml` - Create .env file - Launch Containers - Initial Setup via Browser
- Access http://localhost:8080 and create an admin account.
- Tip: Most DB settings from your .env file will be auto-filled. Just double-check them!
- Useful Commands
- Status check, Update, Start/Stop, and Logs. - Personal Reflection: Using Docker makes maintenance incredibly easy.
