ROX-37174: Use a customized slog-based global logger by mclasmeier · Pull Request #285 · stackrox/roxie

mclasmeier · 2026-09-14T16:14:01Z

Summary by CodeRabbit

New Features
- Added configurable verbose logging with clearer timestamps, styled message levels, and debug output.
Refactor
- Centralized logging across deployment, environment setup, Helm, Kubernetes, and related workflows. Deployment and cleanup behavior remains unchanged.
Tests
- Updated integration and end-to-end tests to reflect logging and context updates.

📝 Walkthrough

Walkthrough

The pull request adds a shared package-level logger with configurable verbosity. Command, deployment, and internal APIs remove injected logger parameters. Helm operations accept context.Context directly. Existing deployment and lookup flows remain, with logging calls and tests updated.

Changes

Shared Logger Migration

Layer / File(s)	Summary
Default logger and output `internal/logger/*`	Adds a default logger API and replaces the logger implementation with a slog-backed handler. Verbose mode controls debug output.
Internal service APIs and Helm `internal/env/`, `internal/k8s/`, `internal/manifest/`, `internal/ocihelper/`, `internal/helpers/`, `internal/imagecache/`, `internal/containerrt/`, `internal/dockerauth/`, `internal/portforward/`, `internal/helm/`	These packages use the package-level logger instead of accepting logger parameters. Helm operations accept `context.Context` directly instead of `HelmCtx`. Related tests update their calls.
Deployer and add-on logging `internal/deployer/*`	Removes logger and verbose state from `Deployer` and add-on configuration. Deployment, teardown, operator, and image-preload logging uses the package-level logger.
Command wiring and callers `cmd/`, `tests/e2e/`	Commands and end-to-end helpers stop passing logger instances. The root command sets logger verbosity from `--verbose`.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Refactor

Merge Risk: 🔵 Low · up to 8db8a

Teardown can print an extra diagnostic without --verbose. This is a bounded output regression, not a blocker to completing teardown.

…tation Rewrite the logger on top of log/slog with a custom Handler that preserves the existing MM:SS-prefixed, color-coded CLI output. New capabilities over the old implementation: - Debug/Debugf (visible only in verbose mode) - LogMultilineYaml (debug-level YAML dump, no-op when not verbose) - SetVerbose / IsVerbose on the instance - Leveled output via slog.Level (LevelDim, LevelSuccess as custom levels) - Errors routed to stderr, everything else to stdout Add default.go with an atomic global singleton (mirrors slog.SetDefault pattern) and package-level forwarding functions so callers can use logger.Info(...) without threading a *Logger through every call site. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…ilineYaml HelmCtx carried a context, a logger, and a verbose flag. With the logger now a package-level singleton and verbose mode queryable via log.IsVerbose() / log.Debug, HelmCtx collapses to plain context.Context. helpers.LogMultilineYaml is superseded by logger.DebugMultilineYaml which uses Debug level (auto-suppressed when not verbose). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Remove the `verbose bool` and `logger *logger.Logger` fields from: - Deployer - AddOnConfig - helmAddOn - imagePreloader / kindImagePreloader / minikubeImagePreloader / customImagePreloader These are replaced by the package-level logger singleton. Constructor signatures are updated accordingly: New() no longer takes a logger, and AddOnConfig becomes an empty struct (retained as an extension point). Also replaces all `d.logger.X()` / `if d.verbose` call sites within these files with `log.X()` / `log.Debug()`. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Mechanical change: every function that accepted a *logger.Logger parameter now uses the package-level log.X() calls instead. Affected packages: k8s, containerrt, ocihelper, manifest, helpers, imagecache, dockerauth, portforward, env, and the remaining deployer call sites (operator, crs, deploy_via_operator, kubectl). The logger import is aliased as "log" throughout. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…mmands - Add PersistentPreRunE on rootCmd to call log.SetVerbose(verbose) once, replacing per-command SetVerbose calls and d.SetVerbose(verbose). - Remove globalLogger and per-command logger.New() instances. - Update deploy, teardown, shell, subshell, env, config to use package-level log.X() calls. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Remove *logger.Logger arguments from test helper calls and constructor invocations. Tests that need isolated logger output use logger.NewWithWriters + logger.SetDefault. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Keep the not-found uninstall message verbose-only.

During roxie teardown, a missing Helm release reaches this branch. log.Dimf is visible at the default nonverbose level, so ordinary runs now print this diagnostic. Use Debugf to preserve the previous HelmCtx.Verbose behavior.

Suggested fix

- log.Dimf("Helm release %q not found in namespace %s, skipping uninstall", releaseName, namespace) + log.Debugf("Helm release %q not found in namespace %s, skipping uninstall", releaseName, namespace)
