Dockerization

Dockerize WordPress: Containers Without Losing Your Content

WordPress in Docker requires special handling — the filesystem is not ephemeral when you have uploads, plugins, and themes to persist. We build WordPress container stacks that separate concerns: PHP-FPM for execution, Nginx for serving, MariaDB for data, and named volumes for wp-content so your media survives container restarts.

Why Dockerize WordPress

WordPress relies heavily on the filesystem — themes, plugins, and uploads live in wp-content/. Naively containerizing WordPress means losing all uploaded media and plugin changes on every restart. But running WordPress on bare metal means dealing with PHP version conflicts, mod_rewrite headaches, and servers that drift into an unmanageable state.

Proper Dockerization solves both problems: the WordPress core runs in an immutable container, while wp-content/uploads, themes, and plugins are mounted as persistent volumes. Updates are controlled, backups are simple, and the environment is reproducible.

Our Docker Implementation for WordPress

Three-container architecture with persistent storage:

PHP-FPM container: FROM wordpress:6-php8.3-fpm-alpine — includes WordPress core with PHP-FPM. Custom php.ini sets upload_max_filesize=64M, post_max_size=64M, memory_limit=256M, and OPcache tuning.
Nginx container: FROM nginx:1.25-alpine — reverse proxy to FPM with FastCGI, serves static files directly, handles URL rewriting for pretty permalinks.
MariaDB container: FROM mariadb:11 — persistent volume for /var/lib/mysql, health check with healthcheck --connect.

Named volumes: wp-content (uploads, themes, plugins), db-data (MariaDB). The Compose file includes a wp-cli service profile for running WP-CLI commands without SSH.
