How to set up a secure, temporary File sharing Portal (Self-Hosted)

Use Case: You need to send sensitive files to a client but don’t trust WeTransfer or Google Drive.

Steps:

Deploy FileRun or Nextcloud in Docker
- Install Docker on your server:
  
  sudo apt install docker.io docker-compose
- Create a docker-compose.yml with FileRun or Nextcloud.
Set Up SSL with Let’s Encrypt
- Use a reverse proxy like Traefik or NGINX with Certbot to issue SSL certs.
Create a Public Upload Folder
- Limit size, set auto-delete after X days, enable password protection.
Send One-Time Secure Links
- Generate a share link with password & expiry date.
Add Fail2Ban or Cloudflare to Prevent Brute Force Attacks

Now you have a secure, private file sharing portal hosted on your own VPS.
