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.
Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

To run this application you need Docker Engine >= 1.10.0
. Docker Compose is recommended with a version 1.6.0
or later.
WordPress requires access to a MySQL or MariaDB database to store information. We'll use our very own MariaDB image for the database requirements.
The main folder of this repository contains a functional docker-compose.yml
file. Run the application using it as shown below:
$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-wordpress/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
If you want to run the application manually instead of using docker-compose
, these are the basic steps you need to run:
$ docker network create wordpress-network
$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
--env ALLOW_EMPTY_PASSWORD=yes \
--env MARIADB_USER=bn_wordpress \
--env MARIADB_DATABASE=bitnami_wordpress \
--network wordpress-network \
--volume mariadb_data:/bitnami/mariadb \
bitnami/mariadb:latest
$ docker volume create --name wordpress_data
$ docker run -d --name wordpress \
-p 8080:8080 -p 8443:8443 \
--env ALLOW_EMPTY_PASSWORD=yes \
--env WORDPRESS_DATABASE_USER=bn_wordpress \
--env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
--network wordpress-network \
--volume wordpress_data:/bitnami/wordpress \
bitnami/wordpress:latest
Access your application at http://your-ip/
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/wordpress
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.
This requires a minor change to the docker-compose.yml
file present in this repository:
...
services:
mariadb:
...
volumes:
- - 'mariadb_data:/bitnami/mariadb'
+ - /path/to/mariadb-persistence:/bitnami/mariadb
...
wordpress:
...
volumes:
- - 'wordpress_data:/bitnami/wordpress
+ - /path/to/wordpress-persistence:/bitnami/wordpress
...
-volumes:
- mariadb_data:
- driver: local
- wordpress_data:
- driver: local
NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID
1001
.
$ docker network create wordpress-network
$ docker run -d --name mariadb \
--env ALLOW_EMPTY_PASSWORD=yes \
--env MARIADB_USER=bn_wordpress \
--env MARIADB_DATABASE=bitnami_wordpress \
--network wordpress-network \
--volume /path/to/mariadb-persistence:/bitnami/mariadb \

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.
$ docker pull bitnami/wordpress:latest
- For docker-compose:
$ docker-compose stop wordpress
- For manual execution:
$ docker stop wordpress
$ 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.
- For docker-compose:
$ docker-compose rm wordpress
- For manual execution:
$ docker rm wordpress
- 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 using an external database for WordPress.
- Modify the
docker-compose.yml
file present in this repository:
wordpress:
...
environment:
- - MARIADB_HOST=mariadb
+ - MARIADB_HOST=mariadb_host
- MARIADB_PORT_NUMBER=3306
- WORDPRESS_DATABASE_NAME=wordpress_db
- WORDPRESS_DATABASE_USER=wordpress_user
- - ALLOW_EMPTY_PASSWORD=yes
+ - WORDPRESS_DATABASE_PASSWORD=wordpress_password

$ docker run -d --name wordpress\
-p 8080:8080 -p 8443:8443 \
--network wordpress-network \
--env MARIADB_HOST=mariadb_host \
--env MARIADB_PORT_NUMBER=3306 \

--env WORDPRESS_DATABASE_USER=wordpress_user \
--env WORDPRESS_DATABASE_PASSWORD=wordpress_password \
--volume wordpress_data:/bitnami/wordpress \
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
.
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 wp help
- Using
docker
command:
$ docker exec wordpress wp help
Find more information about parameters available in the tool in the official documentation.
The Bitnami WordPress Docker image is designed to be extended so it can be used as the base image for your custom web applications.
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
andAPACHE_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'
USER 0 # Required to perform privileged actions
RUN install_packages vim
USER 1001 # Revert to the original non-root user
## 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
- The WordPress container has been migrated to a "non-root" user approach. Previously the container ran as the
root
user and the Apache daemon was started as thedaemon
user. From now on, both the container and the Apache daemon run as user1001
. You can revert this behavior by changingUSER 1001
toUSER root
in the Dockerfile. - Consequences:
- The HTTP/HTTPS ports exposed by the container are now
8080/8443
instead of80/443
. - Backwards compatibility is not guaranteed when data is persisted using docker or docker-compose. We highly recommend migrating the WP site by exporting its content, and importing it on a new WordPress container. In the links below you'll find some alternatives:
- No writing permissions will be granted on
wp-config.php
by default.
- The HTTP/HTTPS ports exposed by the container are now
- 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
.
- 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.
- For performance and security reasons, Apache will set the
AllowOverride
directive toNone
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 ofwordpress-htaccess.conf
compatible with these plugins). If you want to have the default.htaccess
behavior, set theWORDPRESS_HTACCESS_OVERRIDE_NONE
env var tono
.
- wp-cli tool is included in the Docker image. Find it at /opt/bitnami/wp-cli/bin/wp.
