Abstract

This docker-compose allows to easily run a Nextcloud instance with Collabora.

Prerequisites for production use

• Domain records:
  • One record for Nextcloud (eg: nextcloud.example.com)
  • One record for Collabora (eg: collabora.example.com)
  • BOTH records must be (resolvable AND accessible) from (Nextcloud container AND Collabora container AND final users)
• HTTPS for Nextcloud and Collabora (eg: Let’s Encrypt)
• Reverse proxy for SSL termination

Installation

Tweak files

• env

  • Set TZ
  • The timezone to be used in the container (See List_of_tz_database_time_zones)
  • Example: Europe/Paris
  • Generate secure password for POSTGRES_PASSWORD
  • Password to be set (and used) for the Nextcloud database user. It will only be set when postgres files (./data/postgres/data/...) are created. Any further change won’t update it.
  • Example: passwordsgenerator.net
  • Generate secure password for NEXTCLOUD_ADMIN_PASSWORD
  • Password to be set for Nextcloud root user. It will only be set when Nextcloud will install itself. Any further change won’t update it.
  • Example: passwordsgenerator.net

• env_collabora

  • Set domain
  • Regexp for domain(s) allowed to used Collabora. It must match your Nextcloud domain.
  • Example: nextcloud\.example\.com (Note the backslashes to escape the dots)
  • Generate secure password for password
  • Password to be set for Collabora admin panel (https://collabora.example.com/loleaflet/dist/admin/admin.html)
  • Example: passwordsgenerator.net

• docker-compose.yml

  • Set restart policies
  • Uncomment restart lines to allow docker to automatically start the containers on reboot.
