Containerized / Docker Images

⚠️ Memory note: Images based on the SysML v2 Pilot / API Services (gorenje/sysmlv2-jupyter, josh-kaplan/sysml-v2-docker, jaydeanmartin/sysmlv2, mbsemashup/sysmlv2-api.pilotimpl, mycr0ft/sysmlv2-jupyter-container, kenji-miyuke/sysml-v2-docker/eclipse, Open-MBEE sysmlv2-web-modeler, DeciSym sysmlv2-gui, Refinery Validation Showcase) bundle a JVM and often a Spring Boot server alongside JupyterLab/Eclipse. Combined overhead routinely exceeds 8 GB — run them on hosts with ≥ 16 GB RAM (preferably more when also running PostgreSQL). Containerizing is a good way to keep host deps clean, but plan host memory accordingly.
