Switch Squid image to Alpine to remove Berkeley DB/Sleepycat components by Copilot · Pull Request #6507 · github/gh-aw-firewall

Copilot · 2026-07-22T19:08:32Z

AWF’s published Squid image inherited Ubuntu’s Berkeley DB (libdb5.3t64 / libdb-5.3.so) transitively, which causes enterprise license-governance rejection despite not being a direct Squid runtime dependency. This PR moves the Squid image build to an Alpine-based runtime to eliminate that package lineage while preserving AWF’s Squid runtime contract.

Image base + package graph
- Replaced ubuntu/squid:latest with alpine:3.24 in containers/squid/Dockerfile.
- Removed Ubuntu-specific apt mirror/retry/install logic and installed Squid + required runtime utilities via apk.
Runtime compatibility retained
- Preserved non-root execution model and explicit proxy ownership of /var/log/squid, /var/spool/squid, /var/run/squid, and /etc/squid.
- Kept compatibility with existing compose preflight drop-privilege path by including bash + shadow.
- Enforced proxy user/group UID/GID = 13 to maintain existing ownership expectations (including ARC/DinD log-dir behavior).
Documentation alignment
- Updated docs/architecture.md to reflect the Squid container’s Alpine base.

FROM alpine:3.24

RUN apk add --no-cache \
      bash bind-tools curl net-tools netcat-openbsd openssl shadow squid && \
    groupmod -g 13 proxy || addgroup -S -g 13 proxy && \
    usermod -u 13 -g 13 proxy || adduser -S -D -H -u 13 -G proxy proxy

@copilot address review feedback

- Dockerfile: remove Alpine 'news' account (GID 13) before creating proxy at UID/GID 13 using shadow-utils userdel/groupdel + groupadd/useradd - Add .github/workflows/test-squid-image.yml that builds the squid image for both linux/amd64 and linux/arm64 on every PR touching containers/squid/** and asserts: no Berkeley DB/Sleepycat packages, no libdb*.so* shared libraries, proxy user at UID 13, proxy group at GID 13, squid binary present

Copilot · 2026-07-22T20:38:57Z

@copilot address review feedback

Both review issues are addressed in commit fix(squid): fix UID/GID 13 conflict and add multi-arch image validation:

UID/GID 13 conflict (containers/squid/Dockerfile:17-20): Alpine's base image assigns GID 13 to the news group (UID 9 to the news user). The old conditional addgroup -S -g 13 proxy hit GID-in-use and aborted under set -e. The fix removes the news account via shadow-utils userdel/groupdel before creating proxy at UID/GID 13 with groupadd -r -g 13 proxy and useradd -r -u 13 -g proxy -M -s /sbin/nologin proxy.

Multi-arch image validation (containers/squid/Dockerfile:1): Added .github/workflows/test-squid-image.yml — triggered on every PR that touches containers/squid/**, it builds the image separately for linux/amd64 and linux/arm64 (using QEMU emulation for arm64) and asserts:

No Berkeley DB / Sleepycat packages are installed (apk info check)
No libdb*.so* shared libraries exist in the filesystem
proxy user is present at UID 13
proxy group is present at GID 13
squid binary is present and executable

🔬 Smoke Test: API Proxy OpenTelemetry Tracing

Scenario	Status	Notes
1. Module Loading	✅	`otel.js` loads successfully; exports: `startRequestSpan`, `setTokenAttributes`, `setBudgetAttributes`, `endSpan`, `endSpanError`, `shutdown`, `isEnabled` and internal helpers
2. Test Suite	✅	39 tests passed in `otel.test.js` + 20 tests passed in `otel-fanout.test.js` (59 total, 0 failures)
3. Env Var Forwarding	✅	`src/services/agent-environment-credentials.ts` forwards `OTEL_*` vars to containers; tests in `agent-environment-credentials.test.ts` cover `OTEL_SERVICE_NAME`, `OTEL_EXPORTER_OTLP_ENDPOINT`, `OTEL_EXPORTER_OTLP_HEADERS`, and related vars
4. Token Tracker Integration	✅	`onUsage` callback exists in `token-tracker-http.js` as the OTEL hook point; invoked after normalized usage extraction
5. OTEL Diagnostics	✅	`otel.js` supports graceful degradation: falls back to file exporter (`/var/log/api-proxy/otel.jsonl`) when no OTLP endpoint configured; fan-out mode available via `GH_AW_OTLP_ENDPOINTS`
6. Graceful Degradation	✅	Test confirms `FileSpanExporter` is used when no OTLP config present — no errors

Summary: All 6 scenarios pass. The OTEL integration is fully implemented with 59 passing tests covering span creation, token attributes (GenAI semantic conventions), parent context propagation, OTLP export via Squid proxy, fan-out multi-endpoint support, and graceful fallback to file export.
