Installation

Build from Source

Clone this repository and build the image with docker build <arguments> (imagename) .

Prebuilt Images

The following image tags are available along with their tagged release based on what's written in the Changelog:

Version Container OS Tag
23 Alpine :23-latest
22 Alpine :22-latest
21 Alpine :21-latest

Multi Architecture

Images are built primarily for amd64 architecture, and may also include builds for arm/v6, arm/v7, arm64 and others. These variants are all unsupported. Consider sponsoring my work so that I can work with various hardware. To see if this image supports multiple architecures, type docker manifest (image):(tag)

Configuration

Quick Start

The first boot can take from 2 minutes - 5 minutes depending on your CPU to setup the proper schemas.

Persistent Storage

The following directories are used for configuration and can be mapped for persistent storage.

Base Images used

This image relies on an Alpine Linux base image that relies on an init system for added capabilities. Outgoing SMTP capabilities are handlded via msmtp. Individual container performance monitoring is performed by zabbix-agent. Additional tools include: bash,curl,less,logrotate,nano,vim.

Be sure to view the following repositories to understand all the customizable options:

Image Description
OS Base Customized Image based on Alpine Linux
Nginx Nginx webserver
PHP-FPM PHP Interpreter

If you there are features that you wish to override based on the defaults and for some reason the environment variables are not working, create a file called custom.config.php in your data/config directory

Parameter Description Default
ADMIN_USER Admin user e.g. admin
ADMIN_PASS Admin pass e.g. password
DOMAIN The Domain that this is configured for e.g. 'example.org'
DB_TYPE Set the DB_TYPE - e.g. mysql, postgres, sqlite3 sqlite3
DB_HOST Hostname of DB Server e.g. nextcloud-db
DB_NAME Database name e.g. nextcloud
DB_PORT Database port e.g. 3306
DB_USER Username for Database e.g. nextcloud

Upgrading from the 2.x Series

  • If you are upgrading from the 2.x series of images (Nextcloud 20 and below) please note that the following environment variables have been introduced

  • TEMP_DIRECTORY - For holding temporary files

  • CACHE_DIRECTORY - Moving the "Cache" per user out of their user data folder for those using S3 Backend for performance reasons

  • APP_DIRECTORY - Applications downloaded from the App Store

  • DATA_DIRECTORY - Users Data Directory

  • You will also need to export new volumes if you are using the new defaults to these paths above:

Environment Variable 2.x Images volume mapping New Image mapping
APP_DIRECTORY /www/nextcloud/custom-apps /data/apps
CACHE_DIRECTORY unset /data/cache
DATA_DIRECTORY /www/nextcloud/data /data/userdata
SKELETON_DIRECTORY ${NGINX_WEBROOT}/core/skeleton /data/templates/skeleton
TEMP_DIRECTORY unset /data/tmp
  • Additionally you will need to make a change to the database to support the change of the data location as listed here.

Maintenance

Shell Access

For debugging and maintenance purposes you may want access the containers shell.

bash docker exec -it (whatever your container name is) bash

Support

These images were built to serve a specific need in a production environment and gradually have had more functionality added based on requests from the community.

Usage

  • The Discussions board is a great place for working with the community on tips and tricks of using this image.
  • Consider sponsoring me personalized support.

Bugfixes

  • Please, submit a Bug Report if something isn't working as expected. I'll do my best to issue a fix in short order.

Feature Requests

  • Feel free to submit a feature request, however there is no guarantee that it will be added, or at what timeline.
  • Consider sponsoring me regarding development of features.

Updates

  • Best effort to track upstream changes, More priority if I am actively using the image in a production environment.
  • Consider sponsoring me for up to date releases.
