New paid-tier per-customer image built on litespeedtech/openlitespeed:1.8.4-lsphpNN.
Matrix: 8.1-8.5. Native LSAPI suexec to customer uid, server-level LSCache,
all WP/WooCommerce extensions (memcached, redis, imagick, mbstring, etc.) baked in.
Files:
- Dockerfile.litespeed (FROM prebuilt LiteSpeed base, layers wp-cli/composer/mariadb)
- configs/litespeed/{httpd_config,site-template,lsphp-overrides}.tpl
- scripts/{entrypoint,create-vhost,detect-memory}-litespeed.sh + install-lscache-wp.sh
CI: new Build-LiteSpeed-Images matrix job. OLS_VERSION pinned to 1.8.4 (only
release with prebuilt images for all 5 PHP versions on Docker Hub).
Spec: whp/docs/superpowers/specs/2026-06-01-cac-litespeed-design.md
