GLPI 12 reached RC3 on September 30, together with the last GLPI 10 release and a GLPI 11 security release that was replaced the next day. See what changes, how to test it with Docker and what to do now.

GLPI 12 is under development and already shows important changes in the interface, the frontend, the APIs, and the platform's internal structure. In this content, we show what can already be observed, the possible impacts on plugins and integrations, and how to test the development version using the JMBA Soluções Docker image.

Step-by-step to install GLPI 11 with Docker Compose: the five volumes you must persist, secrets in .env, install via console, reverse proxy with SSL, and the fix for the classic crontab-inside-the-container mistake. Plus the pitfall that most often takes GLPI down: recreating the container without persisting /etc/glpi.

How NexTool runs and supports GLPI on Docker for clients: architecture with separate volumes, a production docker-compose, the commands we actually use in support and the best practices (pinned tag, non-root, secrets and volume backup).

A production runbook to upgrade GLPI on Docker across minor and major versions: decision matrix, consistent backup, schema migration, rehearsed rollback and the real pitfalls (lost config_db, OPcache, incompatible plugin) that cause downtime.
