WordPress — system requirementsverification pending

Self-hosted content management system and blogging platform, deployed via the Docker Official Image. · website · repository

No official figure published for: minimum RAM, recommended RAM, minimum CPU cores, recommended CPU cores

wordpress.org's own Requirements page states only software requirements (a PHP version floor, MariaDB or MySQL, HTTPS, and that any server supporting PHP + MySQL will do) — no RAM, CPU, or hardware figures anywhere on the page. hub.docker.com/_/wordpress (the Docker Official Image page) was independently checked the same way and also states no hardware requirement, only software tags/PHP variants and a compose example. Both wordpress.org and make.wordpress.org are blocked by this session's network egress policy (org-level proxy denial, not a fetch failure specific to this page) — the verifier should re-confirm this absence from an unblocked network path.

We publish nothing we can't source. Evidence of the gap.

External services

mysql (required) — source
mariadb (required) — source

WordPress core requires MySQL OR MariaDB — exactly one of the two, never both at once. Modeled as two required:true entries (this one and the paired mariadb entry) only because the schema has no native alternatives construct (Defect Class #11); do not read required:true on both as "both databases running simultaneously". The Docker Official Image's own compose.yaml example (hub.docker.com/_/wordpress) uses `mysql:8.0` specifically; MariaDB is the documented alternative per wordpress.org's own Requirements page. SQLite is not core-supported for a standard install (plugin/drop-in and Playground-sandbox use only, not a standard WordPress install path).

Alternative to MySQL, not an additional required database — pick one, not both, not neither. See the mysql entry's note.

Container

Image: wordpress:latest · compressed size (amd64): 262 MB · architectures: amd64, arm64, armv7 · source, retrieved 2026-09-06

Docker Official Image; `:latest` resolves to `7.1.0-apache` (PHP 8.3) per the Docker Hub tag listing, live-confirmed to exist (Defect Class #14). The manifest list for `:latest` publishes 8 real platforms — amd64, arm64/v8, arm/v7, arm/v5, 386 (i386), ppc64le, riscv64, and s390x — confirmed via the Docker Hub API image list; this schema's arches enum only has slots for three of them (amd64/arm64/armv7), shown here, so the other five (i386, ppc64le, s390x, riscv64, arm/v5) are real but not representable in this field. This is 8 architectures, not the 9 an earlier research note claimed (no arm/v6 build exists on the current manifest — re-verify if that earlier figure resurfaces elsewhere).
