It configures the Docker environment (`DOCKER_HOST`, image paths) and sets the `LAB_COMPUTE_*` variables that session management depends on. **Selection:** - If one compute skill is available, use it — read its SKILL.md and follow setup. - If multiple compute skills are available, ask the user which to use (once per session). - If no compute skills are available, use native compute (see [references/native-compute.md](references/native-compute.md)). - If the user explicitly requests native compute, use it regardless of available compute skills. - Remember the selection for the session duration. ## Tooling Use the wrapper script and task list in [references/tooling.md](references/tooling.md) for all lab interactions. Direct docker or docker-compose invocations bypass session tracking and break lab state management. ## Running Labs and Compute Running-lab state tracking, compute session management, and resource-awareness guidance are in [references/running-labs.md](references/running-labs.md). ## Compose File Format Follow the topology file guidance and template in [references/compose-file.md](references/compose-file.md). --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/ios-xr) — claim your Tome and manage your conversions.
