Labels are workspace-specific free-text annotations that can be applied to pipelines, actions, or workflow runs, either during or after creation. Use labels to organize your work and filter key information.
Labels aren't propagated to Nextflow during workflow execution.
Label names must contain a minimum of 2 and a maximum of 39 alphanumeric characters, separated by dashes or underscores, and must be unique in each workspace.
- Label names cannot begin or end with dashes
- Label names cannot contain a consecutive combination of
- A maximum of 25 labels can be applied to each resource.
- A maximum of 100 labels can be used in each workspace.
Create and apply labels#
Labels can be created, applied, and edited by a workspace owner, admin, or maintainer. When applying a label, users can select from existing labels or add new ones on the fly.
Labels applied to a pipeline#
Labels are applied to elements in a workspace-specific context. This means that labels applied to a shared pipeline in
workspace A will not be shown when viewing the pipeline from
The labels applied to each pipeline are displayed in both list and card views on the Launchpad. Select a pipeline to view all applied labels.
Apply a label when adding a new pipeline or editing an existing pipeline.
If a label is applied to a pipeline, all workflow runs of that pipeline will inherit the label. If the labels applied to the pipeline are changed, this change will only be applied to future runs, not past runs.
Labels applied to an action#
Apply a label when adding a new action or editing an existing action. Labels applied to an action are displayed in the action card on the Actions screen. Hover over labels with + to see all labels.
If a label is applied to an action, all workflow runs triggered by this action inherit the label. If the labels applied to the action are changed, this change will only be applied to future runs, not past runs.
Labels applied to a workflow run#
Labels applied to a workflow run are displayed on the Runs list screen and on the workflow run detail screen. Hover over labels with + to see all labels. Apply a label to a workflow run during launch, on the workflow runs list screen, or on the run detail screen.
Search and filter with labels#
You can search and filter pipelines and workflow runs using one or more labels — filter and search are complementary.
Overview of labels in a workspace#
All labels used in a workspace can be viewed, added, edited, and deleted by a workspace owner, admin, or maintainer in the workspace Settings tab. If a label is edited or deleted on this screen, the change is propagated to all items where the label was used.
You cannot undo editing or deleting a label.
