Run Wordpress in Docker

Source code for running my Wordpress powered blog in Docker containers

Architecture

Three containers:

• MariaDB
• nginx
• FPM/Wordpress

FPM/Wordpress and nginx container shares a folder with all the Wordpress files. Any static files and Wordpress media files are served by nginx directly.

nginx container forwards requests for .php files to the FPM/Wordpress container on a UNIX socket using the FastCGI protocol.

Wordpress uses MariaDB (over another socket) for persistense of posts. Media is persisted on the Docker volume that nginx and Wordpress shares.

How to Use

Development

1. Create volumes for Wordpress and MariaDB data.

   docker volume create blog-db-data docker volume create blog-www-html

2. Build

   docker-compose -f docker-compose.dev.yml build

3. Run

   docker-compose -f docker-compose.dev.yml up

Production

1. Create volumes for Wordpress, MariaDB data and Let's Encrypt certs.

   docker volume create blog-db-data docker volume create blog-www-html docker volume create letsencrypt-certs docker volume create letsencrypt-challenge

2. Build

   docker-compose -f docker-compose.prod.yml build

3. Set passwords as env vars. These are substituted by Docker Compose (example is for PowerShell).

   $env:DB_PASS="YOURDBPASSWORD" $env:WP_ADMIN_PASSWORD="YOURWPPASSWORD"

4. Initialize Wordpress. Use whatever URL is correct for your blog. API keys can be had from Akismet.

   docker-compose -f .\docker-compose.prod.yml run -e WP_API_KEY=YOUR_API_KEY -e WP_URL=localhost -e WP_ADMIN_USER=YOURUSER -e DB_PASS=$env:DB_PASS -e WP_ADMIN_EMAIL=YOUREMAIL -u www-data --entrypoint=/admin/init.sh blog

5. Start the whole edifice
