The tutorial assigned one image through its execution profiles, so it did not show how Nextflow modules declare their own software. Each greeting process now declares debian:12-slim; Docker and Google Batch use those declarations while the standard profile continues to run local commands.

The guide explains per-process selection and image inspection. Existing NF_CONTAINER overrides should move to a module declaration or a withName selector.

Validation

  • Local workflow from an external launch directory produced the expected three greetings.
  • nextflow inspect resolved all three process images for Docker and Workbench (using dummy cloud context; no Batch jobs submitted).
  • Whitespace and documentation checks passed.
  • Docker execution and Workbench verification remain pending.
