Read the LANDIS-II Docker image reference used for a run

landis_image_info.Rd

Looks for <run_dir>/rep*/log/docker_image.log, a one-line sidecar of the form ghcr.io/.../landis-ii-v8-release@sha256:<64hex> written by landis_run_docker() after docker pull. The immutable sha256 digest pins the exact runtime image; an image tag alone is mutable.

Usage

landis_image_info(run_dir)

Arguments

run_dir

Character path to a scenario run directory (containing rep* subdirectories).

Value

A named list with image_name, image_digest, and source:

"captured"

Sidecar present (authoritative; the digest pins the runtime).

"option"

Sidecar absent; image name read from the landisutils.docker.image option on the current host (best-effort; the tag is mutable).

"local"

No sidecar and no Docker option set (a local install).
