crab workflow

Manage workflow-layer state for pipelines defined in crab.yaml.

Synopsis

crab workflow [OPTIONS] <COMMAND>

Commands

Examples

Inspect stage state

crab workflow status

Render a DAG

crab workflow dag
crab workflow dag --format mermaid

Inspect journals and publish cache entries

crab workflow journal ls
crab workflow push-cache --all

The administrative commands do not all share the same mutation boundary. status and dag inspect declared state. journal ls and journal show read run evidence, while journal gc removes older terminal journals. push-cache uploads local stage-cache entries to the configured remote and therefore requires network access and write authorization.

Start diagnosis with status, render dag when dependencies are unclear, and inspect the relevant journal before pruning anything. Run each nested --help because target selectors, formats, and retention controls belong to the subcommand.
