Builds
Goal
Upgrade the wp-proudcity Docker base image from Debian bookworm (12) to trixie (13).
Background
Split out from #2824 (PHP 8.3 upgrade). We deliberately kept the OS pinned to bookworm on that ticket so the PHP bump could be isolated. This is the follow-up to do the OS bump on its own.
Target tag: php:8.3-apache-trixie.
Why separate
Bumping PHP and Debian together means any production regression has two suspects. Doing them in sequence keeps each change debuggable.
Acceptance
Dockerfile FROM updated to php:8.3-apache-trixie.- Image builds cleanly.
- All apt packages still install (package names sometimes change across Debian majors —
libcurl4-openssl-dev, libmcrypt-dev, mariadb-client, etc.).
- All PHP extensions still load (
gd, mysqli, opcache, bcmath, redis, mcrypt).
- WP admin loads in staging, golden-path smoke test passes.
Risks to watch
- Debian trixie ships newer OpenSSL/libcurl — check anything that pins to specific TLS behavior.
mariadb-client major version changes; verify wp-cli db commands still work.- Any pecl extensions compiled against bookworm system libs need rebuild — handled automatically by the image build, but worth confirming.
