Problem

SonarCloud: miscellaneous findings

From the issue: 6 open SonarCloud finding(s) in combsmith/broodly, worst severity BLOCKER. Generated by the org SonarCloud Audit.

Risk

Low — changes automation shell logic under scripts/, covered by shellcheck (--severity=warning) and the bats suite.

Test plan

Tests added/updated: tests/scripts/sonar-infra-hardening.test.sh. Verification: bash scripts/dev-lead-lint.sh (shellcheck --severity=warning) ran pre-commit; the bats suite runs in CI.

Rollback

Revert this PR. No non-revertible side effects (no tags, migrations, or external state).

Monitoring

This PR's Lint (shellcheck) and bats checks show pass/fail; watch subsequent dev-lead / pr-review runs for behavioral regressions.

Closes #614

📝 Summary

Summary by CodeRabbit

  • Security
    • API and background worker services now run with reduced system privileges.
    • Database connections require encryption and the Cloud SQL connector; rules allowing access from the entire internet are rejected.
    • Media storage bucket names are validated to meet supported naming requirements.
  • Monitoring
    • Database activity, including connections, disconnections, checkpoints, and lock waits, is logged.
    • Media storage access logs are collected in a dedicated bucket with uniform access controls, public access prevention, versioning, and a one-year retention period.

The API and worker containers now run as non-root users. Cloud SQL configuration adds connector enforcement, database logging, encrypted-only connections, and validation against unrestricted authorized networks. The media bucket now sends access logs to a dedicated bucket. A Bash regression test checks these settings in CI.

Changes: Infrastructure hardening

Layer / File(s) Summary
Non-root container runtime
apps/api/Dockerfile, apps/api/Dockerfile.worker, tests/scripts/sonar-infra-hardening.test.sh, .github/workflows/ci.yml
Both Dockerfiles set the runtime user to nonroot:nonroot. The Bash regression test checks the final-stage user for both images and runs in the shell-tests CI job.
Cloud SQL logging and connection settings
infra/terraform/modules/cloud-sql/main.tf, infra/terraform/modules/cloud-sql/variables.tf, tests/scripts/sonar-infra-hardening.test.sh
Cloud SQL requires connector enforcement, enables four database logging flags, and sets ssl_mode to ENCRYPTED_ONLY. The authorized-networks validation rejects 0.0.0.0/0 and ::/0. The regression test checks these settings.
Media bucket access logging
infra/terraform/modules/storage/main.tf, infra/terraform/modules/storage/variables.tf, infra/terraform/modules/storage/outputs.tf, tests/scripts/sonar-infra-hardening.test.sh
The media bucket sends access logs to a dedicated bucket. The log bucket has access controls, versioning, a 365-day object lifecycle rule, and an object-creator IAM member. Terraform validates the bucket name and exposes the log bucket name. The regression test checks the logging configuration and IAM grant.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Possibly related issues

  • SonarCloud: miscellaneous findings #614 — The PR changes the Dockerfiles and Cloud SQL settings named in the issue, and adds regression checks. The supplied evidence does not establish that every listed finding is resolved.
Merge Risk: Low · previous review e468a

The Cloud SQL public-IP finding is suppressed instead of fixed, so issue #614's zero-findings acceptance criterion may not be met. Exposure is limited by connector enforcement, encrypted-only connections, and empty default authorized networks. The bucket name validation also misses Cloud Storage reserved words, which causes a late apply-time error. Both are bounded and can be handled with a follow-up or an explicit exception.

Full details: Out of Scope Changes check

Explanation

The changed Terraform variables, storage resources, Dockerfiles, CI test step, and regression test support #614. Connector enforcement, bucket-name validation, IAM configuration, outputs, comments, and tests directly implement or verify the requested hardening. No unrelated change is established by the supplied evidence.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 1 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Linked Issues check

Explanation

The reviewed head implements the six remediation targets in #614. The Dockerfiles set non-root users. Cloud SQL enables the four logging flags, sets ssl_mode = "ENCRYPTED_ONLY", and requires the connector. The configuration rejects open authorized_networks ranges. Storage adds access logging and a protected log bucket. The specific NOSONAR comments identify the Cloud SQL public-IP case and the log sink. The regression test runs in CI. The supplied evidence does not include a SonarCloud result, so zero remaining findings cannot be confirmed.

Resolution

Provide the SonarCloud audit result for the reviewed head, or equivalent evidence, that confirms all six #614 findings are resolved.

Two checks are red, and neither comes from this diff, so I made no code change.

  • Terraform verifies that terraform init resolves every module. It fails because infra/terraform/environments/*/main.tf:199 references ../../modules/firebase, and that directory isn't in the repo. This PR only touches cloud-sql and storage. Fixing it means adding the missing module, which is a separate change. Silencing the check wouldn't fix it.
  • dependency-audit / govulncheck verifies there are no known Go vulnerabilities. It reported "No vulnerabilities found" and then crashed inside vulncheck.FetchVulnerabilities (a vuln-DB fetch error). This PR changes no Go code or dependencies, so it looks like a transient or infrastructure failure. A re-run should clear it.

Inline comments:
Review comments at @infra/terraform/modules/cloud-sql/main.tf:
- Line 56: Set connector enforcement to REQUIRED in the Cloud SQL instance
settings containing ipv4_enabled so public-IP connections must use the
connector, and update the NOSONAR note to accurately describe this enforcement.

Review comments at @infra/terraform/modules/storage/main.tf:
- Line 52: Add validation for var.bucket_name so the derived name formed with
the -access-logs suffix always meets Cloud Storage bucket naming rules,
including length and dotted-name label constraints. Keep the existing derived
access-log bucket naming behavior.

Review comments at @tests/scripts/sonar-infra-hardening.test.sh:
- Line 49: Update the effective-user assertion in the test to verify the
resolved UID is non-root, or restrict the accepted user to the known distroless
identity; do not rely only on the username being nonempty and not spelled “root”
or “0.”
- Line 76: Update the network validation check in the test that reads SQL_VARS
so it verifies the active validation condition rejects 0.0.0.0/0, rather than
merely matching that CIDR anywhere in the file.
- Line 82: Update the STORAGE_MAIN check so it verifies the analytics group,
roles/storage.objectCreator, and destination bucket together in the same IAM
resource, rather than only checking that the group appears in the file.
- Line 12: Add the sonar-infra-hardening.test.sh command to the Shell Tests job
in the CI workflow so CI runs these hardening checks alongside the existing
named scripts and Bats tests.
- Line 56: Update the awk rules for `database_flags`, `name`, and `value` to
match only active, uncommented Terraform lines, so commented-out blocks and
fields cannot satisfy the check. Preserve the assertion that the active flag has
the required value.

Review comments at @infra/terraform/modules/cloud-sql/main.tf:
- Line 61: Remove the NOSONAR suppression and its confirmed-safe justification
from the ipv4_enabled setting: connector enforcement does not disable the public
IPv4 endpoint. If public connectivity is intentional, use the approved exception
process; otherwise disable public IPv4 and implement the required private
connectivity.

Review comments at @infra/terraform/modules/storage/variables.tf:
- Line 24: Update the bucket_name validation to reject names beginning with
“goog” and names containing “google,” so both the media bucket name and its
derived access-log bucket name satisfy the reserved-name rules.
