What is WordPress?
WordPress is a free and open source blogging tool and a content management system (CMS) based on PHP and MySQL, which runs on a web hosting service. Features include a plugin architecture and a template system. WordPress is used by more than 22.0% of the top 10 million websites as of August 2013. WordPress is the most popular blogging system in use on the Web, at more than 60 million websites. The most popular languages used are English, Spanish and Bahasa Indonesia.
How to use this image
docker run --name some-wordpress --link some-mysql:mysql -d wordpress
The following environment variables are also honored for configuring your WordPress instance:
-e WORDPRESS_DB_HOST=...
(defaults to the IP and port of the linkedmysql
container)-e WORDPRESS_DB_USER=...
(defaults to "root")-e WORDPRESS_DB_PASSWORD=...
(defaults to the value of theMYSQL_ROOT_PASSWORD
environment variable from the linkedmysql
container)-e WORDPRESS_DB_NAME=...
(defaults to "wordpress")-e WORDPRESS_AUTH_KEY=...
,-e WORDPRESS_SECURE_AUTH_KEY=...
,-e WORDPRESS_LOGGED_IN_KEY=...
,-e WORDPRESS_NONCE_KEY=...
,-e WORDPRESS_AUTH_SALT=...
,-e WORDPRESS_SECURE_AUTH_SALT=...
,-e WORDPRESS_LOGGED_IN_SALT=...
,-e WORDPRESS_NONCE_SALT=...
(default to unique random SHA1s)
If the WORDPRESS_DB_NAME
specified does not already exist on the given MySQL server, it will be created automatically upon startup of the wordpress
container, provided that the WORDPRESS_DB_USER
specified has the necessary permissions to create it.
If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:
docker run --name some-wordpress --link some-mysql:mysql -p 8080:80 -d wordpress
Then, access it via http://localhost:8080
or http://host-ip:8080
in a browser.
If you'd like to use an external database instead of a linked mysql
container, specify the hostname and port with WORDPRESS_DB_HOST
along with the password in WORDPRESS_DB_PASSWORD
and the username in WORDPRESS_DB_USER
(if it is something other than root
):
docker run --name some-wordpress -e WORDPRESS_DB_HOST=10.1.2.3:3306 \
-e WORDPRESS_DB_USER=... -e WORDPRESS_DB_PASSWORD=... -d wordpress
... via docker-compose
Example docker-compose.yml
for wordpress
:
wordpress:
image: wordpress
links:
- db:mysql
ports:
- 8080:80
db:
image: mariadb
environment:
MYSQL_ROOT_PASSWORD: example
Run docker-compose up
, wait for it to initialize completely, and visit http://localhost:8080
or http://host-ip:8080
.
Adding additional libraries / extensions
This image does not provide any additional PHP extensions or other libraries, even if they are required by popular plugins. There are an infinite number of possible plugins, and they potentially require any extension PHP supports. Including every PHP extension that exists would dramatically increase the image size.
If you need additional PHP extensions, you'll need to create your own image FROM
this one. The documentation of the php
image explains how to compile additional extensions. Additionally, the wordpress
Dockerfile has an example of doing this.
The following Docker Hub features can help with the task of keeping your dependent images up-to-date:
- Automated Builds let Docker Hub automatically build your Dockerfile each time you push changes to it.
- Repository Links can ensure that your image is also rebuilt any time
wordpress
is updated.
Supported Docker versions
This image is officially supported on Docker version 1.6.2.
Support for older versions (down to 1.0) is provided on a best-effort basis.
