# ACDL v1.1 Spike — AWS Bootstrap Runbook
|
|
|
|
Phase 08 bootstraps the AWS substrate for the v1.1 spike. It uses the
|
|
**root account credential for account 581513795199 exactly once**, then
|
|
closes D-034 by having the user manually rotate the root key afterward.
|
|
|
|
> **Spike scope (D-039):** the spike uses a per-run-rotated IAM *user* key
|
|
> (`acdl-spike-runner`), NOT OIDC. Real OIDC federation is deferred to
|
|
> v1.2 (blocked on go-gitea/gitea#36988 — Gitea Actions does not support
|
|
> `id-token: write`). The `acdl-spike-runner` user + its key are deleted
|
|
> in v1.2 cleanup when the OIDC role lands.
|
|
|
|
## Steps
|
|
|
|
1. **Set the bootstrap root key in env** (never commit, never echo):
|
|
```bash
|
|
export ACDL_BOOTSTRAP_AWS_ACCESS_KEY_ID="<root key>"
|
|
export ACDL_BOOTSTRAP_AWS_SECRET_ACCESS_KEY="<root secret>"
|
|
export AWS_DEFAULT_REGION="us-east-1"
|
|
```
|
|
|
|
2. **Create the state backend** (S3 bucket + DynamoDB outbox table):
|
|
```bash
|
|
python3 terraform/bootstrap/create_state_backend.py
|
|
```
|
|
Idempotent; writes `terraform/bootstrap/.bootstrap_state.json` marker.
|
|
|
|
3. **Create the IAM user + scoped policy + initial key**:
|
|
```bash
|
|
python3 terraform/bootstrap/create_iam_user.py
|
|
```
|
|
Prints `ACDL_AWS_ACCESS_KEY_ID=<...>` + `ACDL_AWS_SECRET_ACCESS_KEY=<...>`
|
|
to stdout (capture if you want the initial key; `rotate_spike_key.sh`
|
|
creates a fresh one anyway).
|
|
|
|
4. **Rotate the spike key** (creates a new key, deactivates+deletes old,
|
|
writes the new key to gitignored `.env.secrets`):
|
|
```bash
|
|
bash scripts/rotate_spike_key.sh
|
|
```
|
|
Optionally uploads to Gitea Actions secrets if `ACDL_GITEA_TOKEN` is set.
|
|
|
|
5. **Verify**:
|
|
```bash
|
|
bash scripts/verify_phase08.sh
|
|
```
|
|
Asserts: caller identity is `acdl-spike-runner` (not root); S3 bucket +
|
|
DynamoDB table + IAM user + scoped policy all exist; `.env.secrets` +
|
|
`.bootstrap_state.json` are gitignored.
|
|
|
|
6. **MANUAL — D-034 closure:** rotate/deactivate the **root** key in the
|
|
AWS IAM console (the user does this, not the script). The bootstrap
|
|
root key has now served its one-shot purpose; the spike uses the
|
|
rotated `acdl-spike-runner` key for Phases 09-10.
|
|
|
|
## What the spike uses for Phases 09-10
|
|
|
|
- **State backend:** S3 bucket `acdl-tfstate-581513795199-us-east-1` +
|
|
DynamoDB table `acdl-outbox` (one table for both lock + outbox, D-P08-1).
|
|
- **Auth:** the rotated `acdl-spike-runner` key in `.env.secrets`
|
|
(gitignored, chmod 600). Re-rotate after each spike run via
|
|
`rotate_spike_key.sh` (D-039).
|
|
|
|
## Spike scope vs v1.2 boundary
|
|
|
|
| Concern | Spike (Phase 08) | v1.2 |
|
|
|---------|------------------|------|
|
|
| AWS auth | per-run-rotated long-lived key (D-039 waiver) | real OIDC federation (go-gitea/gitea#36988) |
|
|
| IAM | minimal user `acdl-spike-runner` + scoped policy | OIDC role + trust policy (no user, no key) |
|
|
| State backend | S3 + DynamoDB single-region (us-east-1) | multi-region |
|
|
| Secret storage | gitignored `.env.secrets` + optional Gitea secret | Gitea OIDC-issued web-identity token (no secret) | |
