bootstrap/sops (age-keygen refusing in-repo, .sops.yaml, install-age-key.sh glue installing the sops-age Secret) + bootstrap/flux (bootstrap.sh: flux install -> apply -k clusters/dev; decryption/url patches). PM wiring: place .sops.yaml at repo root (SOPS walks to root); inline the 3 flux patches into clusters/dev (avoids kustomize ../ load-restriction). clusters/dev builds with decryption enabled; full CI gate PASS. No key material; nothing executed. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

# age-keygen.sh — generate the SOPS age keypair for the platform.
|
|
#
|
|
# Phase 1, T-1.4 (ADR-0007 SOPS+age, R-SEC-01). AUTHORED, NOT RUN.
|
|
# =============================================================================
|
|
# *** THE OPERATOR RUNS THIS, ONCE, AT BOOTSTRAP. AGENTS MUST NOT RUN IT. ***
|
|
# =============================================================================
|
|
#
|
|
# What it does:
|
|
# - Generates an age keypair to a path OUTSIDE this git repo (default:
|
|
# ~/.config/sops/age/keys.txt — SOPS's conventional location, honoured by the
|
|
# SOPS_AGE_KEY_FILE default lookup).
|
|
# - Prints ONLY the PUBLIC recipient (age1...) to stdout. The public recipient
|
|
# is safe to paste into bootstrap/sops/.sops.yaml. The PRIVATE key stays in
|
|
# the file and is NEVER printed, NEVER committed (see .gitignore: age.key,
|
|
# *.key). Spec docs/07 + AGENTS.md §5: no secret material in logs/PR/output.
|
|
#
|
|
# Hard guarantees:
|
|
# - REFUSES to write anywhere inside this repository (private key must never
|
|
# land where git could track it).
|
|
# - REFUSES to overwrite an existing key file (rotation is deliberate — see
|
|
# age-key-secret.md "Rotation").
|
|
#
|
|
# Next step after running this: install the private key into the cluster as the
|
|
# `sops-age` Secret — see age-key-secret.md. Then paste the printed recipient
|
|
# into .sops.yaml.
