What is WordPress with NGINX?

WordPress with NGINX combines the most popular blogging application with the power of the NGINX web server.

https://www.wordpress.org/ https://nginx.org/

TL;DR;

Docker Compose

$ git clone https://github.com/bitnami/bitnami-docker-wordpress-nginx
$ cd bitnami-docker-wordpress-nginx/4
$ docker-compose up

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.

Supported tags and respective Dockerfile links

NOTE: Debian 8 images have been deprecated in favor of Debian 9 images. Bitnami will not longer publish new Docker images based on Debian 8.

Prerequisites

To run this application you need Docker Engine >= 1.10.0. Docker Compose is recommended with a version 1.6.0 or later.

How to use this image

WordPress requires access to a MySQL or MariaDB database to store information. We'll use our very own MariaDB image for the database requirements.

Using Docker Compose

The recommended way to run WordPress is using Docker Compose using the docker-compose.yml file that you can find into the different directories, depending on the distro you want to use.

Launch the containers using:

$ docker-compose up -d

Using the Docker Command Line

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a network
$ docker network create wordpress-tier
  1. Create a volume for MariaDB persistence and create a MariaDB container
$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_wordpress \
  -e MARIADB_DATABASE=bitnami_wordpress \
  --net wordpress-tier \
  --volume mariadb_data:/bitnami \
  bitnami/mariadb:latest
  1. Create volumes for WordPress persistence and launch the container
$ docker volume create --name wordpress_data
$ docker run -d --name wordpress -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e WORDPRESS_DATABASE_USER=bn_wordpress \
  -e WORDPRESS_DATABASE_NAME=bitnami_wordpress \
  --net wordpress-tier \
  --volume wordpress_data:/bitnami \
  --volume ./wordpress-vhosts.conf:/bitnami/nginx/conf/vhosts/wordpress-vhosts.conf \
  bitnami/wordpress-nginx:latest

Access your application at http://your-ip/

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define docker volumes namely mariadb_data and wordpress_data. The Wordpress application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

The following docker-compose.yml template demonstrates the use of host directories as data volumes.

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_wordpress
      - MARIADB_DATABASE=bitnami_wordpress
    volumes:
      - /path/to/mariadb-persistence:/bitnami
  wordpress:
    image: bitnami/wordpress-nginx:latest-rhel-7
    depends_on:
      - mariadb
    ports:
      - '80:80'
      - '443:443'
    environment:
      - WORDPRESS_DATABASE_USER=bn_wordpress
      - WORDPRESS_DATABASE_NAME=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - /path/to/wordpress-persistence:/bitnami
      - ./wordpress-vhosts.conf:/bitnami/nginx/conf/vhosts/wordpress-vhosts.conf

Upgrading WordPress

Bitnami provides up-to-date versions of MariaDB and WordPress, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the WordPress container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

The bitnami/wordpress-nginx:latest tag always points to the most recent release. To get the most recent release you can simple repull the latest tag from the Docker Hub with docker pull bitnami/wordpress-nginx:latest. However it is recommended to use tagged versions.

  1. Get the updated images:
$ docker pull bitnami/wordpress-nginx:latest
  1. Stop your container
  • For docker-compose: $ docker-compose stop wordpress
  • For manual execution: $ docker stop wordpress
  1. Take a snapshot of the application state
$ rsync -a /path/to/wordpress-persistence /path/to/wordpress-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the MariaDB data

You can use these snapshots to restore the application state should the upgrade fail.

  1. Remove the stopped container
  • For docker-compose: $ docker-compose rm wordpress
  • For manual execution: $ docker rm wordpress
  1. Run the new image
  • For docker-compose: $ docker-compose start wordpress
  • For manual execution (mount the directories if needed): docker run --name wordpress bitnami/wordpress-nginx:latest

  bitnami/wordpress-nginx:latest

Connect WordPress docker container to an existing database

The Bitnami WordPress container supports connecting the WordPress application to an external database. In order to configure it, you should set the following environment variables:
