Enable HTTPS for NextCloud Docker using docker-compose

By default, NextCloud Docker doesn't enable HTTPS.

Steps

Create

• Create folders
  • /app/nextcloud/data/db: for MySQL database
  • /app/nextcloud/data/db_conf: for MySQL database configuration (don't see anything in it)
  • /app/nextcloud/data/cert: for nextcloud certificates
  • /app/nextcloud/data/html: for nextcloud data and packages
• Create docker-compose.yml
• Create Dockerfile.nextcloud
• Run docker-compose build
• Run docker-compose up -d

Destroy

• Run docker-compose down
