Closes #80

Summary

Adds per-app registry credentials that are passed to Docker during image builds, allowing apps to use base images from private registries (e.g. ghcr.io, private Harbor, ECR, etc.).

Changes

Database

  • New migration 007_add_registry_credentials.sql — creates registry_credentials table with app_id, registry, username, password columns, unique constraint on (app_id, registry), cascade delete on app removal

Model (internal/models/registry_credential.go)

  • RegistryCredential struct following the Active Record pattern used by all other models
  • NewRegistryCredential() constructor
  • Save() — insert or update
  • Delete() — remove credential
  • FindRegistryCredential() — find by ID
  • FindRegistryCredentialsByAppID() — find all for an app
  • App.GetRegistryCredentials() — convenience method on the App model

Docker Client (internal/docker/client.go)

  • New RegistryAuth struct for passing registry credentials
  • BuildImageOptions.RegistryAuths field
  • buildAuthConfigs() helper to convert []RegistryAuth to Docker SDK's map[string]registry.AuthConfig
  • Auth configs are passed to ImageBuild when present, enabling the Docker daemon to authenticate when pulling private base images during builds

Deploy Service (internal/service/deploy/deploy.go)

  • buildRegistryAuths() method fetches app's registry credentials and converts to []docker.RegistryAuth
  • Called during buildImage — credentials are passed to Docker build transparently
  • Failure to fetch credentials is logged as a warning but doesn't block builds (public images still work)

Handlers & Routes

  • HandleRegistryCredentialAdd() — POST /apps/{id}/registry-credentials
  • HandleRegistryCredentialEdit() — POST /apps/{id}/registry-credentials/{credID}/edit
  • HandleRegistryCredentialDelete() — POST /apps/{id}/registry-credentials/{credID}/delete
  • All handlers validate ownership (credential must belong to the app in the URL path)

UI (templates/app_detail.html)

  • New "Registry Credentials" card between Environment Variables and Docker Labels
  • Descriptive text explaining the purpose
  • Table showing existing credentials with registry, username, masked password
  • Inline edit form (Alpine.js toggle)
  • Delete with confirmation dialog
  • Add form with registry, username, password fields

Tests

  • TestRegistryCredentialCreateAndFind — create + query
  • TestRegistryCredentialUpdate — update in place
  • TestRegistryCredentialDelete — deletion
  • TestRegistryCredentialFindByIDNotFound — nil/nil for missing
  • TestAppGetRegistryCredentials — convenience method
  • Cascade delete test updated to verify registry credentials are cleaned up
  • TestBuildAuthConfigsEmpty / TestBuildAuthConfigsSingle / TestBuildAuthConfigsMultiple — auth config builder
  • TestRegistryAuthStruct — type instantiation

README

  • Added "Private Docker registry authentication for base images" to Features list

Corrupted Doc Comment in internal/service/deploy/deploy.go

The buildRegistryAuths function was inserted between the writeLogsToFile doc comment and the writeLogsToFile function body. This results in:

Lines 1238–1242:

// writeLogsToFile writes the deployment logs to a file on disk.
// Structure: DataDir/logs/<hostname>/<appname>/<appname>_<sha>_<timestamp>.log.txt
// buildRegistryAuths fetches registry credentials for an app and converts them
// to Docker RegistryAuth objects for use during image builds.
func (svc *Service) buildRegistryAuths(

Go treats all four comment lines as the godoc for buildRegistryAuths(), so:

  • buildRegistryAuths has a misleading doc starting with "writeLogsToFile writes the deployment logs…"
  • writeLogsToFile (line 1268) has no doc comment at all — its original comment was stolen

Fix: Move the writeLogsToFile comment lines down to sit directly above func (svc *Service) writeLogsToFile(...), and keep only the buildRegistryAuths comment above buildRegistryAuths.

Requirements Checklist (from issue #80)

Requirement Status
Support authenticating to private Docker registries for base images Implemented
Per-app credential storage registry_credentials table with cascade delete
Credentials passed to Docker during builds Via BuildImageOptions.RegistryAuthsAuthConfigs
UI for managing credentials Add/edit/delete with masked passwords
Graceful degradation (public images still work) Credential fetch failure logged as warning, build continues

Code Quality Notes (non-blocking, for context)

  • Ownership validation in edit/delete handlers correctly checks cred.AppID != appID — prevents cross-app access
  • Schema follows existing patterns (app_env_vars, app_labels) with no timestamps — consistent
  • Passwords stored in plaintext in SQLite — consistent with existing credential handling in this codebase (webhook secrets, SSH keys)

Build Result

$ docker build .
# All stages pass (fmt-check, lint, test, build) ✅

Verdict: FAIL

The corrupted doc comment in deploy.go is a concrete correctness bug — buildRegistryAuths has the wrong godoc, and writeLogsToFile lost its documentation. This needs to be fixed before merge.

Rework: Fix corrupted doc comment in deploy.go

Issue: The buildRegistryAuths function was inserted between the writeLogsToFile doc comment and the writeLogsToFile function body, causing Go to treat the writeLogsToFile comment as godoc for buildRegistryAuths.

Fix: Moved the two writeLogsToFile comment lines (// writeLogsToFile writes the deployment logs... and // Structure: DataDir/logs/...) down to sit directly above func (svc *Service) writeLogsToFile(...), so each function now has its own correct doc comment.

Verification:

  • gofmt — clean
  • docker build . — all stages pass (fmt-check, lint, test, build)
  • README — feature listed

Previous Review Issue: Godoc Comments

The previous review FAILed because buildRegistryAuths was inserted between writeLogsToFile's doc comment and function body.

Verified FIXED. In internal/service/deploy/deploy.go:

  • buildRegistryAuths (line ~1238) has its own correct doc comment: "buildRegistryAuths fetches registry credentials for an app…"
  • writeLogsToFile (line ~1270) has its own correct doc comment: "writeLogsToFile writes the deployment logs to a file on disk." with the structure line
  • Both functions have proper, non-corrupted godoc.

All new exported types and functions have test coverage.

Code Quality & Security Notes

  • Ownership validation: Edit/delete handlers correctly check cred.AppID != appID — prevents cross-app credential access.
  • Schema consistency: Follows existing patterns (app_labels, app_env_vars) with ON DELETE CASCADE and index on app_id.
  • Passwords stored plaintext in SQLite: Consistent with existing credential handling in this codebase (webhook secrets, SSH keys). Not ideal but not a regression.
  • Input validation: Empty fields silently redirect (no error message to user) — matches existing handler patterns.
  • nolint directives: gosec for password fields and nilnil for Active Record "not found" — both justified and consistent with existing code.
  • testpackage nolint in auth_test.go: Justified — tests unexported buildAuthConfigs.
  • Error handling in buildImage: buildRegistryAuths failure is warn-logged and build continues with nil auths — correct graceful degradation.

Build Result

$ docker build .
# fmt-check ✅ | lint ✅ | test ✅ | build ✅
# All stages pass.

Verdict: PASS

The previous review's godoc issue is properly fixed. All requirements from issue #80 are implemented. Policy compliance is clean. Tests cover all new exports. Build passes. No cheating detected.
