Emi Griffith	657e27ba9f	openbao: render Centralis from the vault ... Centralis could not migrate at all. `seed-from-sops.sh --all` refused centralis.prod with `CENTRALIS_TOKENS: contains a shell metacharacter`, and render-secrets-openbao.sh had no Centralis path whatsoever — so the seeded data would have had nothing to read it. Both halves come from applying the app stack's rules to a file that does not share its shape. /etc/thermograph.env is raw unquoted KEY=value. /etc/centralis.env is consumed by exactly one thing and that thing is a shell: sudo bash -c 'set -a && . /etc/centralis.env && set +a && docker compose up' CENTRALIS_TOKENS is JSON, so it can never satisfy a no-metacharacters rule, and rendering it unquoted is precisely the 2026-07-24 failure: bash strips the quotes, Centralis fails closed on the malformed registry and serves a single `shared` identity, indistinguishable from the file never being written. So: - seed-from-sops.sh validates against the renderer that will consume the path. The dotenv rules still apply to common and env/*; centralis/* is exempt because it is single-quoted downstream. - render-secrets-openbao.sh gains thermograph_render_openbao_centralis, mirroring render_centralis_secrets: fetch as JSON, emit POSIX single-quoted assignments, then PROVE the file by sourcing it under `env -i` with `set -a` and comparing every value back before anything touches the destination. Mirrored rather than shared, per the existing note above thermograph_render_openbao — consolidate when the SOPS path is deleted. - render_centralis_secrets gains the same early-return backend dispatch the app path already uses, so the new function is reachable. Without it the SOPS path was the only path regardless of TG_SECRETS_BACKEND. Verified against a synthetic registry containing a JSON token map, an apostrophe, and `$(...)`/backtick/backslash/double-quote payloads: 5 keys round-trip byte-for-byte through `set -a; . file`, CENTRALIS_TOKENS parses to the right subjects, and the command substitution does not execute. The negative case is covered too — fed the unquoted 2026-07-24 shape, the round-trip check reports the value as changed (by length, never content) and refuses to write. Also corrects the claim in render-secrets-openbao.sh that the SOPS path never tripped the metacharacter hazard "because every current value happens to be alphanumeric". CENTRALIS_TOKENS is the counter-example; it never tripped those paths because it was never in them.	2026-07-30 19:55:17 -07:00
Emi Griffith	6bd07d33cb	openbao: add a dormant OpenBao backend alongside SOPS ... Phase 1 of moving the secret store to OpenBao. Nothing is cut over: TG_SECRETS_BACKEND defaults to sops for all three environments, so SOPS remains authoritative until an environment is flipped in a reviewed PR. The reason for the migration is one specific failure class. infra/CLAUDE.md requires that vps1 never hold prod credentials, but that rule is currently enforced by a caller-side shell flag (THERMOGRAPH_SECRETS_SKIP_COMMON) at three call sites. A fourth call site, or one by-hand render, writes both S3 keypairs, the VAPID private key, REGISTRY_TOKEN and the IndexNow/metrics tokens onto the Forgejo CI-runner box and exits 0. policies/tg-host-dev.hcl makes that a 403 instead: dev's identity cannot read the common path at all. Shape: - vps2 only, native systemd (not a container: a Swarm service is circular, and a plain docker run is one `prune -a` from gone), raft storage (2.6.0 deprecated the file backend), static auto-unseal so a reboot cannot block deploys, mesh-only self-signed TLS (not ACME — that would put DNS in the boot chain of the secret store). - AppRole per environment, CIDR-bound, 5-minute tokens. Each environment's secret-id is owned by its own deploy user, which is a boundary that does not exist today since prod and beta both reach the same root-owned age key. - Render still produces the same raw unquoted dotenv: Centralis compares /etc/thermograph.env textually and the Swarm entrypoint parses it by line. The backend dispatch in render-secrets.sh returns early rather than refactoring the shared write path, so the SOPS path stays byte-identical. Verified by rendering dev (12 keys) and prod (32 keys) through it, matching the live hosts. The duplicated write path is noted for consolidation once prod has been on OpenBao for a release cycle. The OpenBao renderer rejects values containing a newline or a shell metacharacter. /etc/thermograph.env is sourced by bash in six places, so such a value is a command-execution path on the deploy host; the SOPS path has always had this hazard and avoids it only because every current value happens to be alphanumeric. Also records that the age keypair is NOT retired by this migration: it is the backup encryption key for every off-box dump (ops-cron.yml:142,197, 30-day retention), so deleting it with the vault files would silently destroy a month of database recoverability. verify-parity.sh is the cutover gate — it renders both backends and diffs them, reporting key names and counts only, never values.	2026-07-29 21:35:20 -07:00
