What is WordPress?

WordPress is one of the most versatile open source content management systems on the market. WordPress is built for high performance and is scalable to many servers, has easy integration via REST, JSON, SOAP and other formats, and features a whopping 15,000 plugins to extend and customize the application for just about any type of website.

$ 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.
All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.
All Bitnami images available in Docker Hub are signed with Docker Content Trust (DTC). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

How to deploy WordPress in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami WordPress Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

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 NOTE: RHEL images are not available in any public registry. You can build them on your side on top of RHEL as described on this doc.

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 following docker-compose.yml template:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    volumes:
      - 'mariadb_data:/bitnami'
    environment:
      - MARIADB_USER=bn_wordpress
      - MARIADB_DATABASE=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes
  wordpress:
    image: 'bitnami/wordpress:latest'
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - 'wordpress_data:/bitnami'
    depends_on:
      - mariadb
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - WORDPRESS_DATABASE_USER=bn_wordpress
      - WORDPRESS_DATABASE_NAME=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes

volumes:
  mariadb_data:
    driver: local
  wordpress_data:
    driver: local

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:

Create a network

$ docker network create wordpress-tier

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

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 \
  bitnami/wordpress: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:latest
    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

Mount host directories as data volumes using the Docker command line

Create a network (if it does not exist)

$ docker network create wordpress-tier

Create a MariaDB container with host volume

$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_wordpress \
  -e MARIADB_DATABASE=bitnami_wordpress \
  --net wordpress-tier \
  --volume /path/to/mariadb-persistence:/bitnami \
  bitnami/mariadb:latest

Create the WordPress the container with host volumes

$ 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 /path/to/wordpress-persistence:/bitnami \
  bitnami/wordpress:latest

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: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:latest. However it is recommended to use tagged versions.

Get the updated images:

$ docker pull bitnami/wordpress:latest

Stop your container

For docker-compose: $ docker-compose stop wordpress
For manual execution: $ docker stop wordpress

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.

Remove the stopped container

For docker-compose: $ docker-compose rm wordpress
For manual execution: $ docker rm wordpress

Run the new image

For docker-compose: $ docker-compose up wordpress
For manual execution (mount the directories if needed): docker run --name wordpress bitnami/wordpress:latest

This would be an example of SMTP configuration using a GMail account:

docker-compose (application part):

  wordpress:
    image: bitnami/wordpress:latest
    ports:
      - 80:80
      - 443:443
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - WORDPRESS_DATABASE_USER=bn_wordpress
      - WORDPRESS_DATABASE_NAME=bitnami_wordpress
      - SMTP_HOST=smtp.gmail.com

For manual execution:

$ docker run -d --name wordpress -p 80:80 -p 443:443 \
  --net wordpress-tier \
  --env SMTP_HOST=smtp.gmail.com --env SMTP_PORT=587 \
  --env [email protected] --env SMTP_PASSWORD=your_password \
  --env ALLOW_EMPTY_PASSWORD=yes --env WORDPRESS_DATABASE_USER=bn_wordpress \
  --env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
  --volume wordpress_data:/bitnami/wordpress \
  bitnami/wordpress: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:

MARIADB_HOST: Hostname for MariaDB server. Default: mariadb
MARIADB_PORT_NUMBER: Port used by MariaDB server. Default: 3306
WORDPRESS_DATABASE_NAME: Database name that WordPress will use to connect with the database. Default: bitnami_wordpress
WORDPRESS_DATABASE_USER: Database user that WordPress will use to connect with the database. Default: bn_wordpress
WORDPRESS_DATABASE_PASSWORD: Database password that WordPress will use to connect with the database. No defaults.

This would be an example of using an external database for WordPress.

docker-compose:

  wordpress:
    image: bitnami/wordpress:latest
    ports:
      - 80:80
      - 443:443
    environment:
      - MARIADB_HOST=mariadb_host
      - MARIADB_PORT_NUMBER=3306
      - WORDPRESS_DATABASE_NAME=wordpress_db
      - WORDPRESS_DATABASE_USER=wordpress_user
      - WORDPRESS_DATABASE_PASSWORD=wordpress_password
    volumes:
      - wordpress_data:/bitnami

For manual execution:

$ docker run -d --name wordpress -p 80:80 -p 443:443 \
  --net wordpress-tier \
  --env MARIADB_HOST=mariadb_host \
  --env MARIADB_PORT_NUMBER=3306 \
  --env WORDPRESS_DATABASE_NAME=wordpress_db \
  --env WORDPRESS_DATABASE_USER=wordpress_user \
  --env WORDPRESS_DATABASE_PASSWORD=wordpress_password \
  --volume wordpress_data:/bitnami \
  bitnami/wordpress:latest

In case the database already contains data from a previous WordPress installation, you need to set the variable WORDPRESS_SKIP_INSTALL to yes. Otherwise, the container would execute the installation wizard and could modify the existing data in the database. Note that, when setting WORDPRESS_SKIP_INSTALL to yes, the values WORDPRESS_USERNAME, WORDPRESS_PASSWORD, WORDPRESS_BLOG_NAME, WORDPRESS_EMAIL, WORDPRESS_BLOG_NAME and WORDPRESS_SMTP_* variables will be ignored. Make sure that, in this imported database, the table prefix matches the one set in WORDPRESS_TABLE_PREFIX.

WP-CLI tool

The Bitnami WordPress container includes the command line interface wp-cli that can help you to manage and interact with your WP sites. To run this tool, please note you need use the proper system user, daemon.

This would be an example of using wp-cli to display the help menu:

Using docker-compose command:

$ docker-compose exec wordpress sudo -u daemon -- wp help

Using docker command:

$ docker exec wordpress sudo -u daemon -- wp help

Find more information about parameters available in the tool in the official documentation.

Customize this image

The Bitnami WordPress Docker image is designed to be extended so it can be used as the base image for your custom web applications.

Extend this image

Before extending this image, please note there are certain configuration settings you can modify using the original image:

Settings that can be adapted using environment variables. For instance, you can change the ports used by Apache for HTTP and HTTPS, by setting the environment variables APACHE_HTTP_PORT_NUMBER and APACHE_HTTPS_PORT_NUMBER respectively.
Adding custom virtual hosts.
Replacing the 'httpd.conf' file.
Using custom SSL certificates.

If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:

FROM bitnami/wordpress
## Put your customizations below
...

Here is an example of extending the image with the following modifications:

Install the vim editor
Modify the Apache configuration file
Modify the ports used by Apache

FROM bitnami/wordpress
LABEL maintainer "Bitnami <[email protected]>"

## Install 'vim'
RUN install_packages vim

## Enable mod_ratelimit module
RUN sed -i -r 's/#LoadModule ratelimit_module/LoadModule ratelimit_module/' /opt/bitnami/apache/conf/httpd.conf

## Modify the ports used by Apache by default
# It is also possible to change these environment variables at runtime
ENV APACHE_HTTP_PORT_NUMBER=8181 
ENV APACHE_HTTPS_PORT_NUMBER=8143
EXPOSE 8181 8143

Based on the extended image, you can use a Docker Compose file like the one below to add other features:

version: '2'
services:
  mariadb:
    image: 'bitnami/mariadb:10.3'
    volumes:
      - 'mariadb_data:/bitnami'
    environment:
      - MARIADB_USER=bn_wordpress
      - MARIADB_DATABASE=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes
  wordpress:
    build: .
    ports:
      - '80:8181'
      - '443:8143'
    volumes:
      - 'wordpress_data:/bitnami'
    depends_on:
      - mariadb
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - WORDPRESS_DATABASE_USER=bn_wordpress
      - WORDPRESS_DATABASE_NAME=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes
volumes:
  mariadb_data:
    driver: local
  wordpress_data:
    driver: local

Notable Changes

5.2.1-debian-9-r9 and 5.2.1-ol-7-r9

This image has been adapted so it's easier to customize. See the Customize this image section for more information.
The Apache configuration volume (/bitnami/apache) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the Apache configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom Apache configuration files are advised to mount a volume for the configuration at /opt/bitnami/apache/conf, or mount specific configuration files individually.
The PHP configuration volume (/bitnami/php) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the PHP configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom PHP configuration files are advised to mount a volume for the configuration at /opt/bitnami/php/conf, or mount specific configuration files individually.
Enabling custom Apache certificates by placing them at /opt/bitnami/apache/certs has been deprecated, and support for this functionality will be dropped in the near future. Users wanting to enable custom certificates are advised to mount their certificate files on top of the preconfigured ones at /certs.

5.1.1-r28, 5.1.1-rhel-7-r31 and 5.1.1-ol-7-r30

Users reported that they wanted to import their WordPress database from other installations, such as this ticket. Now, in order to cover this use case, the variable WORDPRESS_SKIP_INSTALL can be set to avoid the container launch the WordPress installation wizard.

5.0.3-r20

For performance and security reasons, Apache will set the AllowOverride directive to None by default. This means that, instead of using .htaccess files, all the default directives will be moved to the /opt/bitnami/wordpress/wordpress-htaccess.conf file. The only downside of this is the compatibility with certain plugins, which would require changes in that file (you would need to mount a modified version of wordpress-htaccess.conf compatible with these plugins). If you want to have the default .htaccess behavior, set the WORDPRESS_HTACCESS_OVERRIDE_NONE env var to no.

5.0.0-r0

wp-cli tool is included in the Docker image. Find it at /opt/bitnami/wp-cli/bin/wp.
