Docker Compose and WordPress

Use WordPress locally with Docker using Docker compose

This setup comes shipped with:

A Dockerfile for extending a base image and using a custom Docker image with an automated build on Docker Hub
Custom domain for example myapp.local
Custom nginx config in ./nginx
Custom PHP php.ini config in ./config
Volumes for nginx, wordpress and mariadb
Bedrock - modern development tools, easier configuration, and an improved secured folder structure for WordPress
Composer
WP-CLI - WP-CLI is the command-line interface for WordPress.
PhpMyAdmin - free and open source administration tool for MySQL and MariaDB
CLI scripts
- Create a self signed SSL certificate for using https
- Trust certs in macOS System Keychain
- Setup the local domain in your in /etc/hosts

Setup

Requirements

Docker
Openssl for creatng the SSL cert. Install using Homebrew brew install openssl

Setup environment variables

Easily set your own local domain, db settings and more. Start by creating .env files, like the examples below.

For Docker and the cli scripts

Copy .env-example in the project root to .env and edit your preferences.

Example:

IP=127.0.0.1
APP_NAME=myapp
DOMAIN="myapp.local"
DB_HOST=mysql
DB_NAME=myapp
DB_ROOT_PASSWORD=password
DB_TABLE_PREFIX=wp_

For WordPress

Copy .env-example in the src folder to .env and edit your preferences.

Use the following database settings:

DB_HOST=mysql:3306
DB_NAME=myapp
DB_USER=root
DB_PASSWORD=password

Create SSL cert

cd cli
./create-cert.sh

Note: OpenSSL needs to be installed.

Trust the cert in macOS Keychain

Chrome and Safari will trust the certs using this script.

In Firefox: Select Advanced, Select the Encryption tab, Click View Certificates. Navigate to where you stored the certificate and click Open, Click Import.

cd cli
./trust-cert.sh

Add the local domain in /etc/hosts

To be able to use for example https://myapp.local in our browser, we need to modify the /etc/hosts file on our local machine to point the custom domain name. The /etc/hosts file contains a mapping of IP addresses to URLs.

cd cli
./setup-hosts-file.sh

The helper script can both add or remove a entry from /etc/hosts. First enter the domain name, then press "a" for add, or "r" to remove. Follow the instructions on the screen.

Install WordPress and Composer dependencies

cd src
docker-compose run composer install

If you have Composer installed on your computer you can also use cd src && composer install

Run

docker-compose up -d

Docker Compose will start all the services for you:

Starting myapp-mysql    ... done
Starting myapp-composer ... done
Starting myapp-phpmyadmin ... done
Starting myapp-wordpress  ... done
Starting myapp-nginx      ... done

🚀 Open up https://myapp.local

PhpMyAdmin

PhpMyAdmin comes installed as a service in docker-compose.

Open http://127.0.0.1:8080/

Notes:

When making changes to the Dockerfile, use:

docker-compose up -d --force-recreate --build

Tools

wp-cli

docker exec -it myapp-wordpress bash

Login to the container

wp search-replace https://olddomain.com https://newdomain.com --allow-root

Run a wp-cli command like this

You can use this command first after you've installed WordPress using Composer as the example above.
