Use dagger call to chain Dagger module functions across multiple modules using module dependencies declared in dagger.json

domain: dagger.io · 5 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. In your module's dagger.json, add a 'dependencies' array referencing another published or local Dagger module by its address (e.g., a GitHub URL with a version tag)
  2. Run 'dagger develop' to regenerate the SDK bindings so the dependency module's functions become available as methods on a generated client type
  3. In your module code, call the dependency module's functions via the generated client, passing Dagger objects (containers, directories, secrets) across the module boundary
  4. Use 'dagger call' from the CLI to invoke your function end-to-end, verifying that the dependency module's logic is executed within the same engine session
  5. Pin the dependency to a specific version or commit in dagger.json to ensure reproducibility across CI runs
