fix(apphost): pin MongoDB to mongo:7 with mongo-data-v7 volume#346
Merged
Conversation
- Add .WithImageTag("7") to prevent MongoDB 8.x AVX/SIGSEGV crash (exit 139)
- Rename volume to mongo-data-v7 to avoid featureCompatibilityVersion 8.2
mismatch crash (exit 62) when reusing an 8.x-initialised volume
- Bump Aspire.AppHost.Sdk from 13.3.2 to 13.3.3 to align with Directory.Packages.props
- Add MongoDbContainerConfigurationTests regression suite (Gimli)
- Update squad history and decisions for boromir, gimli, sam

Pull request overview
This PR fixes local Aspire MongoDB startup failures by pinning the AppHost MongoDB container to MongoDB 7 and moving it to a version-suffixed data volume, with regression coverage and squad process notes.
Changes:
- Pins AppHost MongoDB to
mongo:7andmongo-data-v7. - Aligns the AppHost SDK version with centralized Aspire package versions.
- Adds AppHost regression tests and documents the operational decision/history.

| Pin the MongoDB container image to a stable tag in AppHost.cs: | ||

| ```csharp | ||
| var mongo = builder.AddMongoDB("mongodb") | ||
| .WithImageTag("8.0") // pin away from 8.2 which SIGSEGVs | ||
| .WithDataVolume("mongo-data") |

| ### mongo:8.2 (Aspire.Hosting.MongoDB 13.3.3 default) causes exit 139 (SIGSEGV) | ||
|
|

| When diagnosing MongoDB container crashes under Aspire, check the image tag first. Exit code 139 is SIGSEGV — an image-level crash, not an application wiring defect. The fix is to pin the container image with `.WithImageTag("8.0")` in AppHost. Web timeout logs are downstream symptoms of the container crash and should not be mistaken for wiring bugs. |

## Summary Closes #348 Working as Boromir (DevOps/Infra) + Sam (Backend) + Gimli (Tester). ## Root Cause After PR #346 (mongo:7 + mongo-data-v7 fix) was merged, MongoDB containers continued crashing in the running environment. Investigation revealed the active Aspire AppHost was built from the **main repo's stale local `dev` branch** — 2 commits behind `origin/dev`, still launching `mongo:8.2` → exit 139 (SIGSEGV/AVX). Identified via: `ps aux | grep AppHost.dll` — DLL path revealed the wrong repo root. ## Changes ### Boromir (DevOps/Infra) - Pulled and rebuilt main repo AppHost (`git pull origin dev` + `dotnet build`) — **0 errors**, MongoDB now uses `mongo:7` + `mongo-data-v7`. - Added rule 6 to `.squad/skills/mongodb-dba-patterns/SKILL.md`: sync main repo before starting Aspire; use `ps aux | grep AppHost.dll` to identify the active build. - Added investigation findings to `boromir/history.md`. ### Sam (Backend) - Full backend audit: `MongoDbBlogPostRepository`, `MongoDbCategoryRepository`, `BlogDbContext`, `Program.cs` — all correct. **No production code change required.** - Added findings to `sam/history.md`. ### Gimli (Tester) - Added `SeedMyBlogData_Makes_Seeded_Posts_Visible_On_The_Blog_Page` integration test to `MongoSeedDataIntegrationTests` — asserts seeded posts are visible via the real AppHost-wired Web/MongoDB path. - Added findings to `gimli/history.md`. ## Validation - `MongoDbContainerConfigurationTests` — 4/4 ✅ - `Web.Tests.Integration` (Testcontainers) — 29/29 ✅ - All pre-push gates passed (markdownlint, build, unit tests, integration tests) ✅ - AppHost.Tests build: 0 errors, 0 warnings ✅ ## Volume State | Volume | Status | |---|---| | `mongo-data` |⚠️ FCV-contaminated (mongo:8.2 data, UUID-format). Do not use with mongo:7. | | `mongo-data-v7` | ✅ Clean, numeric-ident format, lock file 0 bytes. Safe for mongo:7. | --------- Co-authored-by: Boromir <boromir@squad.dev> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
