Error message

generating : %w

What it means

`skaffold generate-pipeline` asks the runner to generate a CI pipeline file (pipeline.yaml) from the skaffold configs via `r.GeneratePipeline`. This wrapper propagates any error from that generation. It means the runner could not produce a valid pipeline config, often because the underlying skaffold configs failed to load, the configs are for an unsupported structure, or the runner itself failed to initialize.

Solutions

  1. Confirm the skaffold config file(s) parse: run `skaffold diagnose -f <file>` to see load errors first.
  2. Check the --config flag values point at valid skaffold.yaml files.
  3. Since generate-pipeline is deprecated/limited, generate the CI config with your CI system's native tooling instead.
  4. Update skaffold — newer versions removed unsupported generate-pipeline paths.

Example fix

// before: command against a broken config
skaffold generate-pipeline --config skaffold.yaml
// after: validate the config first, fix errors, then retry
skaffold diagnose -f skaffold.yaml
skaffold generate-pipeline --config skaffold.yaml
Defensive patterns

Strategy: validation

Validate before calling

// Validate the configs load cleanly before attempting generate-pipeline
const diag = execFileSync('skaffold', ['diagnose', '-f', 'skaffold.yaml'], {stdio: 'pipe'});
if (diag.length && /error|invalid|failed/i.test(diag.toString())) throw new Error('skaffold.yaml has errors; generate-pipeline would fail');

Try / catch

try {
  execFileSync('skaffold', ['generate-pipeline', '--config', 'skaffold.yaml']);
} catch (e) {
  const msg = e.stderr?.toString() ?? '';
  if (msg.includes('generating')) {
    console.error('Pipeline generation failed; validate configs with `skaffold diagnose` or use CI-native tooling.');
  } else throw e;
}

Prevention

When it happens

Trigger: Running `skaffold generate-pipeline` where `r.GeneratePipeline(ctx, out, configs, configFiles, "pipeline.yaml")` fails — e.g. the skaffold.yaml(s) listed in --config could not be loaded into the runner, or pipeline generation doesn't support the config's contents.

Common situations: Legacy command used against configs with build/test/deploy sections it can't translate; config files missing or unparseable; running in environments where the runner factory fails (bad kubecontext config etc.).
