The Zot Open Container Initiative (OCI) registry uses ephemeral emptyDir storage when persistence is disabled during installation. In this configuration, registry artifacts are lost when the pod restarts or is rescheduled.
In an air-gapped deployment, the AIWorkloads that PaletteAI deploys must resolve their images and charts from the internal Zot registry. To make that registry available to workload templates without manual setup, PaletteAI injects a set of registry variables into the system VariableSet named mural-variables. Workload profiles reference these variables with the {{ var. }} macro syntax.
