WordPress with Redis Object Cache
de cloudimg
WordPress with a Redis object cache, the world's most used CMS tuned for speed.
WordPress is the world's most widely deployed content management system, powering a large share of the public web thanks to its enormous ecosystem of themes and plugins. This cloudimg image pairs WordPress with a Redis object cache so repeated database queries are served from memory: WordPress feels faster and the database does less work as traffic grows. The stack is Apache 2.4, PHP 8.3, MySQL 8.0 and Redis, all from Ubuntu 24.04, with the Redis Object Cache plugin activated and its object-cache drop-in reporting Connected.
Installed and ready. cloudimg builds the image with WordPress installed to /var/www/html/wordpress, the Redis object cache enabled, and Apache, MySQL and Redis enabled to start on boot, so the site and the /wp-admin backend answer the moment the instance boots — no setup wizard to complete. Redis is bound to loopback only and used purely as the WordPress object cache.
Secure by default and asserted, not assumed. The image ships no known credential: on each machine's first boot cloudimg rotates a fresh WordPress administrator password, a fresh database password, a fresh Redis password and fresh WordPress authentication salts, and sets the site address from the machine's own address. Every value is written to a root only file. Two machines built from this image never share a credential, and a blank, default or guessed admin password is rejected. MySQL and Redis bind to loopback only, no MySQL root password ships, and no swap is baked into the disk.
Open source and shipped unmodified. WordPress core is licensed GPL-2.0-or-later, the Redis Object Cache plugin is GPLv3, and the bundled Redis server is Ubuntu 24.04's redis-server 7.0.x, which is BSD-3-Clause (the community/BSD Redis, not the RSALv2/SSPL upstream Redis 7.4+). There is no paid tier, subscription, licence key or support contract required to run the software. The cloudimg charge covers packaging, secure-by-default hardening and 24/7 support. cloudimg is not affiliated with or endorsed by the WordPress Foundation or Redis; the names are used nominatively to identify the software the image contains.
