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

Setup vhost in /etc/hosts

cd cli
./setup-hosts-file.sh

Follow the instructions.

Setup nginx config

Replace myapp.local in nginx/wordpress_ssl.conf with your own local domain of choice.

Install WordPress and Composer dependencies

docker-compose run composer intall

If you have Composer installed on your Mac 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 now 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
wp search-replace https://olddomain.com https://newdomain.com --allow-root

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