Project runtimes let LStack manage the software represented by a project. Runtime configuration is separate from AI worker execution: a project may have a runtime even when no worker is active.
Runtime modes
Build sources
Container-backed runtimes can use a project Dockerfile, a prebuilt image, or a Compose configuration. The dashboard exposes build, start, stop, restart, rebuild, health, and log operations appropriate to the configured mode.
Docker is required for container-backed runtimes. stack mode also requires Docker Compose v2.
Templates
Runtime templates provide starting configurations for common project types. Applying a template updates runtime configuration only; it does not create a ticket or automatically ask a worker to change the project.
