docs: add k6 preparation steps to the dev-database fixture runbook - #643
Conversation
📝 WalkthroughWalkthroughThe runbook documents direct k6 execution against a seeded debug database. It adds credential, Owner, seed, rate-limit, execution, metric, cleanup, and development Changesk6 debug database workflow
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The runbook currently risks making the k6 preparation fail by restoring rate limits before the smoke test, and its wipe guidance is too narrow about other failures that can leave partial data. These bounded instructions should be clarified before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
Full details: Description checkExplanation The description clearly explains why the runbook needs changes, lists the documented workflow, and records verification details and limitations. It uses separate Why, What, and Verification headings instead of the template headings and omits the checklist, but the required substance is mostly present.

@coderabbitai Round 2 addressed across 8694073 and e09ba0b.
Please re-review. |
The runbook seeds the simulation fixture into a Compose or Aspire dev database, but the fixture it produces cannot be driven by k6: the cast password is hand-chosen rather than taken from `.env.sim`, the Owner `.sim-cast.json` names is never created, and nothing rotates it off `MustChangePassword`, so the Owner VU 403s on every request. Add a "Preparing this database for k6" section covering both forms: generate the cast with `bootstrap.sh` (which starts no container and touches no compose project), seed with those values rather than chosen ones, create and rotate the Owner, raise the three rate-limit buckets via the API's user-secrets so they bind under `aspire run` too, then point `BASE_URL` at the API. Records two things the harness stack hides: the personas write, so a k6 run pushes the account past the exact counts the seed validates, and `MapFallbackToFile` is a no-op in dev, so k6's `staticAssets` flow 404s unless the API is given a `wwwroot`. `reset.sh` and `run-baseline.sh` remain off-limits against a debug database; only direct `k6 run` is supported.
Two defects in the "Preparing this database for k6" section, both found by review on #643. Ordering: the section ran `seed --profile simulation` (k2) before `bootstrap-admin` (k3). The seed refuses to write a row without an Owner in the default account (#500), and `bootstrap-admin` is a silent no-op once any Owner exists (#283) — so as written the seed either fails outright, or an Owner minted at some other address permanently blocks the `admin@<EmailDomain>` one the k6 Owner VU logs in as. Swapped the two steps, so the runbook now matches the order `tools/simulation/reset.sh` uses (bootstrap-admin, rotate, seed), and said why the order is load-bearing rather than leaving it implicit. Cleanup: the setup raises `RateLimiting:Login`, `:Refresh` and `:ClientErrors` to 1,000,000, but the teardown removed only `Login`, leaving two limiters effectively off in the dev box's user-secrets. Removes all three.
…ll it Removing the three `RateLimiting:*:PermitLimit` user-secrets does not restore the production limits on a running process. `AddCluckworkRateLimiting` binds the section once at service registration and passes the ints straight into the `DistributedIpFixedWindowPolicy` instances; nothing re-reads configuration afterwards. So the runbook's cleanup, followed as written, left a dev box serving a 1,000,000 login budget off a user-secrets file that no longer mentions one — clean-looking config, limiter still off. Says so, with the reference. Also adds a second drill for the k6 preparation path. The existing drill covers form A's seed and its recovery arithmetic only, and cannot cover k2: that step needs an Owner at one specific address on an account that has none, which is incompatible with the first drill's step 2. The new drill asserts the two failure modes that are otherwise silent — `Admin already provisioned` standing in for a created Owner, and a cleanup that does not actually restore the limiter (auth-smoke must go red on 429s once it does).
The k6 drill's steps 2 and 3 are one-shot verbs, so under Aspire they hit the Compose database unless given an explicit ConnectionStrings__Default (#565) — the same trap k2 and k3 already warn about, which the drill repeated without the warning.
#644 removed the ceiling box from step 2 but left the knobs table in step 4 pointing at it. The runbook now says depth is unbounded in one place and 'see the ceiling above' in another.

Two instances of one mistake, both mine from the previous commit: drill steps written as shorthand references rather than as commands an operator can run. Step 1 said `down -v && up -d` "as above", which is not a command. Step 5 ran `k6 run` with no BASE_URL, which is worse than not running — it defaults to http://127.0.0.1:8081 (tools/simulation/k6/config.js), the sim stack, so the drill would have exercised a database this runbook never touches and reported whatever it found there. Both are now full commands, and step 5 says why the variable has to be set rather than leaving it to be inferred from k5.

Separate rate-limit setup from cleanup in the drill.
The linked k4 section contains both the set commands and the remove commands. If an operator follows the section before step 5, the elevated limits can be removed before auth-smoke.js runs. Step 6 then repeats the cleanup. State that step 4 runs only the three set commands and the restart.
Proposed clarification

One issue remains in drill step 6. It says: This is still shorthand, not an executable command. It also does not explicitly identify the development API URL. Replace it with the full command from step 5, with the operator’s actual development API URL. This keeps the cleanup check copy-pasteable and prevents an accidental k6 run against the default simulation stack. 🧠 Learnings usedYou are interacting with an AI system. |

Why
docs/runbooks/simulation-fixture-on-a-dev-database.md(#639) seeds the simulation fixture into a Compose or Aspire dev database, but the fixture it produces cannot be driven by k6. Three gaps, all silent:'choose-a-20-char-password') rather than the onetools/simulation/.sim-cast.jsoncarries, so every cast login 401s;admin@sim.local) is never created — the runbook'sbootstrap-adminprerequisite only requires an Owner at any address;MustChangePassword, soMustChangePasswordMiddleware403s every request the Owner VU makes. WithCAPACITY_VUSdefaulting to 10 = one VU per cast user, that is a failed run, not a degraded one.What
A new "Preparing this database for k6" section, covering both the Compose and Aspire forms:
bootstrap.sh. It starts no container and names no compose project, so it is safe to run for this purpose; only itsSimulation__*andSIM_ADMIN_*lines apply to a dev API.ConnectionStrings__Default, per Developer experience: add an Aspire AppHost for local orchestration and observability #565).bootstrap-adminat the cast file's address, then the login + change-password rotationreset.shalready does.Login/Refresh/ClientErrorspast the production defaults (10/900s, 60/900s, 10/300s). A baseline rep logs in 12 times before it starts, so it otherwise measures the limiter. Set via the API's user-secrets, which the AppHost does not override.BASE_URLat the API.Plus two things the harness stack hides:
SimulationDataSeedervalidates, so the nextseed --profile simulationfails closed — the same wipe-only trap as step 1, reached from the other direction.MapFallbackToFileis a no-op in dev (nowwwroot), so k6'sstaticAssetsflow 404s.
