Install prerequisites

For now, this project has been mainly created for Unix (Linux/MacOS). Perhaps it could work on Windows.

All requisites should be available for your distribution. The most important are :

• Composer
• Git
• Docker
• Docker Compose

Installation

Step 0: Clone Repository

Clone this repository in your preferred location.

git clone https://github.com/tareq1988/wp-docker.git wordpress
cd wordpress

Step 1: Dependency Install

Copy the .env-example file to .env. It contains the NGINX hostname and MySQL database credentials. After filling that up, run:

make install
make install-plugins

Step 2: WordPress Configuration

The above command will install the dependencies in place. To complete the WordPress installation, you've to configure the /src/.env file for to Bedrock use. Copy the /src/.env.example to /src/.env file and change the MySQL table and username as configured on the root .env file.

Important: Set your DB_HOST to mariadb in the /src/.env file.

Site URL: The default WordPress site URL will be http://wordpress.local:8080 which is defined in the root .env file as the Nginx Host NGINX_HOST=wordpress.local. If you change this to something else, make sure you also change this value in /src/.env file, the WP_HOME configuration (WP_HOME=http://wordpress.local:8080). The port name has to be appended.

Application Salt: Generate the salt from the generator and replace it on /src/.env file.

Configure Host File: You've to configure your /etc/hosts file to point the site URL to 127.0.0.1. As we are using http://wordpress.local as our hostname, add this config in your /etc/hosts file.

sudo vi /etc/hosts

Add config:

127.0.0.1	wordpress.local

Now save and exit.

Step 3: Run

Now as all the configuration is done, run the docker instance.

make docker-start

This will simply run docker in detached mode with this command: docker-compose up -d

Go to http://wordpress.local:8080 in your browser and you should see the WordPress installation page.

WordPress Setup

We are using Bedrock as our WordPress starter kit.

When using make install command, the required dependencies will be installed automatically. With the command make install-plugins, the following plugins will be installed as a composer dependency:

• Disable Emojis
• Nginx Cache
• Redis Cache
• Debug Bar
• Query Monitor

Page Cache: By default, we will be using Nginx Fastcgi Cache and the Nginx Cache plugin will be the helper to clear the cache. In the plugin settings, you have to save the path to /var/run/nginx-cache as the clear path.

If you don't want to use fastcgi cache, edit the /conf/nginx/site.template.conf and comment or remove the line include global/wpfc-php.conf; and uncomment include global/php.conf; file.

Object Cache: We will be using Redis as our persistant object cache backend. The Redis Cache plugin will be used to conditionally clear out the redis cache storage. The command make install-plugins will automatically install the plugin and will put the object-cache.php in the required location (/web/app/object-cache.php).

In order to take the redis cache setup complete, you've to manually add this line define('WP_REDIS_HOST', 'redis'); in the /src/config/application.php file.

Use Makefile

When developing, you can use Makefile for doing the following operations :

Name	Description
install	Run docker build and install bedrock
install-plugins	Install the required WP plugins
clean	Clean directories for reset
docker-start	Create and start containers
docker-stop	Stop and clear all services
logs	Follow log output
mysql-dump	Create backup of whole database
mysql-restore	Restore backup from whole database

Examples

Start the application :

make docker-start

Show help :

make help
