Wordpress in Docker

Wordpress in Docker

The whole idea was to make starting new (or not new) WordPress project as easy as possible. Wordpress in Docker is a set of files to easily run WordPress in an isolated environment built with Docker containers. If you ever need something improved, added, or bugfixed, do not hesitate contacting me at [email protected].

What is inside:

Installation

Case 1: Setup new project

docker-compose up starts everything you require for new project. Once up, you'll get ready WordPress website on http://localhost:8000 and phpMyAdmin running on http://localhost:8001.
Note: Once you login in WordPress admin I highly recommend you to update WordPress and all plugins to latest versions if any available.

WordPress is the latest official 4.8 version extended with following:

  • Included Bones theme.
  • Included some essential, but not activated, plugins (Advanced Contact Fields, Contact Form 7, WP Mail SMTP, WP Migrate DB). Please let me know if you need more.
  • Included .gitignore file.
  • Removed all default themes and plugins.

Case 2: Setup existing project which was not under docker previously

Tricky part starts when you already have a project and want to start it and not default wordpress installation. To achieve this, do the following (the easiest way):

  • Replace db_dump.sql file with your database dump file. USE `wordpress`; must exist in your file!!! Otherwise docker has no idea where to import this dump. If not there, please add this row at a very top of file.
  • Replace all files in ./wordpress/ folder with your files.
  • Open wp-config.php file in your text editor and replace following rows:
/** The name of the database for WordPress */  
define('DB_NAME', '**********');  
/** MySQL database username */  
define('DB_USER', '**********');  
/** MySQL database password */  
define('DB_PASSWORD', '**********');  
/** MySQL hostname */  
define('DB_HOST', '**********');

with these rows:

/** The name of the database for WordPress */  
define('DB_NAME', 'wordpress');  
/** MySQL database username */  
define('DB_USER', 'user');  
/** MySQL database password */  
define('DB_PASSWORD', 'password');  
/** MySQL hostname */  
define('DB_HOST', 'wordpress_db:3306');
  • Start your project with docker-compose up.

Case 2: Setup existing project which was under docker previously

  • Just pull all files from git and run setup from Case 1.

Useful commands

Database Backup

docker exec wordpress_db /usr/bin/mysqldump -uuser -ppassword -B wordpress wordpress > db_dump.sql

Database Restore

cat db_dump.sql | docker exec -i wordpress_db /usr/bin/mysql -uuser -ppassword wordpress

Accessing containers shell

docker exec -it wordpress bash  
docker exec -it wordpress_db bash

Accessing MySQL server inside container from host

mysql -h0.0.0.0 -P3307 -uroot -proot

Tech

Wordpress in Docker uses a number of open source projects to work properly:

  • Docker Amazing tool which does the whole magic.
  • WordPress Open source software you can use to create a beautiful website, blog, or app.
  • phpMyAdmin Although it's not essential here for things to work, I decided to include it as this is amazing free software tool, intended to handle the administration of MySQL over the Web.
  • Official Docker Repositories WordPress, MySQL, phpMyAdmin
