Prerequisites and Assumptions

• Assumes you are using some sort of SSL terminating reverse proxy such as:
  • Traefik
  • Nginx
  • Caddy

Installation

Build from Source

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

Prebuilt Images

Builds of the image are available on Docker Hub

docker pull docker.io/tiredofit/wordpress:(imagetag)

Builds of the image are also available on the Github Container Registry

docker pull ghcr.io/tiredofit/docker-wordpress:(imagetag)

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

Multi Architecture

Images are built primarily for amd64 architecture, and may also include builds for 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 quickest way to get started is using docker-compose. See the examples folder for a working compose.yml that can be modified for development or production use.

• Set various environment variables to understand the capabilities of this image.

• Map persistent storage for access to configuration and data files for backup.

Persistent Storage

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

Environment Variables

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.

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

Networking

The following ports are exposed.

Maintenance

Shell Access

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

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

Local Development / Changing Site Name & Ports

Wordpress assets are delivered by means of the initial Site URL, and if you wish to develop locally or on a different port you will experience strange results. If you are performing local development then you would want to setup your environment variables as such:

• ENABLE_HTTPS_REVERSE_PROXY=FALSE
• SITE_URL=localhost
• SITE_PORT=8000 (or whatever port you are exposing)

When you are ready to deploy to a production URL - you would change it as such:

• ENABLE_HTTPS_REVERSE_PROXY=TRUE
• SITE_URL=www.domain.com

The system will rotate the URLs in the wordpress configuration files and database automatically upon restart of the container.

Command Line

If you wish to use the included wp-cli tool to perform maintenance use it as such:

cd /www/wordpress
wp-cli <argument>

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.

• Consider sponsoring me for 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.
