Introduction

We wrote a series of articles explaining in depth the philosophy behind this project:

Requirements

Well, to run a Docker environment, you will need Docker. The Dockerfile is only for an Apache+PHP+Wordpress container, you will need a MySQL or MariaDB container to run a website. We use Docker Compose 1.6+ for the orchestration.

Getting started

This project has 2 parts: the Docker environment and a set of tools for theme development. To quickly get started, you can simply run the following:

# copy the files
git clone https://github.com/visiblevc/wordpress-starter.git

# navigate to example directory
cd wordpress-starter/example

# start the website at localhost:8080
docker-compose up -d && docker-compose logs -f wordpress

# stop the website
docker-compose stop

# ssh in to running wordpress site
docker exec -it example_wordpress_1 /bin/bash
(where example_wordpress_1 matches the services in your docker-compose.yml)

NOTE: If you run on MacOS with Docker in VirtualBox, you will want to forward the port by running this VBoxManage controlvm vm-name natpf1 "tcp8080,tcp,127.0.0.1,8080,,8080". If you use another port than 8080, change it in the command.

Default Wordpress Admin Credentials

To access the Wordpress Admin at /wp-admin, the default values are as follows:

Credential	Value	Notes
Username or Email	`root` or `admin@wordpress.com`	Can be changed with the `ADMIN_EMAIL` environment variable
Password	`root`	Uses the same value as the `DB_PASS` environment variable

Default Database Credentials

Credential	Value	Notes
Hostname	`db`	Can be changed with the `DB_HOST` environment variable NOTE:: Must match database service name
Username	`root`
Password		Must be set using the `DB_PASS` environment variable
Database Name	`wordpress`	Can be changed with the `DB_NAME` environment variable
Admin Email	`admin@${DB_NAME}.com`

Service Environment Variables

Notes:

Variables marked with ✅ are required
Single quotes must surround boolean environment variables

`wordpress`

Variable	Default Value	Description
`DB_USER`	`root`	Username for both the database and the WordPress installation (if not importing existing)
`DB_PASS`✅		Password for the database. Value must match `MYSQL_ROOT_PASSWORD` set in the `db` service
`DB_HOST`	`db`	Hostname for the database
`DB_NAME`	`wordpress`	Name of the database
`DB_PREFIX`	`wp_`	Prefix for the database
`SERVER_NAME`	`localhost`	Set this to `<your-domain-name>.<your-domain-extension>` if you plan on obtaining SSL certificates
`ADMIN_EMAIL`	`admin@${DB_NAME}.com`	Administrator email address
`WP_DEBUG`	`'false'`	Click here for more information
`WP_DEBUG_DISPLAY`	`'false'`	Click here for more information
`WP_DEBUG_LOG`	`'false'`	Click here for more information
`WP_VERSION`	`latest`	Specify the WordPress version to install. Accepts any valid semver number, `latest`, or `nightly` for beta builds.
`THEMES`		Comma-separated list of themes you want to install in either of the following forms `theme-slug`: Used when installing theme direct from WordPress.org `[theme-slug]https://themesite.com/theme.zip`: Used when installing theme from URL

`URL_REPLACE`		Comma-separated string in the form of `current-url,replacement-url` When defined, `current-url` will be replaced with `replacement-url` on build (useful for development environments utilizing a database copied from a live site) Note: If you are running Docker using Docker Machine, your replacement url MUST be the output of the following command: `echo $(docker-machine ip <your-machine-name>):8080`

`db`

Variable	Default Value	Description
`MYSQL_ROOT_PASSWORD`✅		Must match `DB_PASS` of the `wordpress` service

Workflow Tips

Using `wp-cli`

You can access wp-cli by running npm run wp .... Here are some examples:

npm run wp plugin install <some-plugin>
npm run wp db import /data/database.sql

Working with Databases

If you have an exported .sql file from an existing website, drop the file into the data/ folder. The first time you run the container, it will detect the SQL dump and use it as a database. If it doesn't find one, it will create a fresh database.

If the SQL dump changes for some reason, you can reload the database by running:

docker-compose exec wordpress /bin/bash "wp db import $(find /data/*.sql | head -n 1) --allow-root"

If you want to create a dump of your development database, you can run:

docker-compose exec wordpress /bin/bash 'wp db export /data --allow-root'

Finally, sometimes your development environment runs on a different domain than your live one. The live will be example.com and the development localhost:8080. This project does a search and replace for you. You can set the URL_REPLACE: example.com,localhost:8080 environment variable in the docker-compose.yml.

Using in Production

Adjustments to `docker-compose.yml`

# If something isn't shown, assume it's the same as the examples above
version: '3'
services:
  wordpress:
    ports:
      - 80:80
      - 443:443
    restart: always
    environment:
      SERVER_NAME: mysite.com
      DB_PASS: ${SECURE_PASSWORD} # Stored in .env file
    volumes:
      - ./letsencrypt:/etc/letsencrypt
      - ./data:/data
      # anything else you'd like to be able to back up
  db:
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: ${SECURE_PASSWORD} # Stored in .env file

SSL Certificates

We highly recommend securing your site with SSL encryption. The Let's Encrypt and Certbot projects have made doing this both free (as in beer) and painless. We've incorporated these projects into this project.

Assuming your site is running on your production host, follow the below steps to obtain and renew SSL certificates.

Obtaining Certificates

$ docker-compose ps
Name                   Command                        State
---------------------------------------------------------
project_db_1           docker-entrypoint.sh mysqld     Up
project_wordpress_1    docker-php-entrypoint /run.sh   Up

$ docker-compose exec wordpress /bin/bash
root@4e16c7fe4a10:/app# certbot --apache

Renewing Certificates

$ docker-compose ps
Name                   Command                        State
---------------------------------------------------------
project_db_1           docker-entrypoint.sh mysqld     Up
project_wordpress_1    docker-php-entrypoint /run.sh   Up

$ docker-compose exec wordpress /bin/bash
root@4e16c7fe4a10:/app# certbot renew
