# ─────────────────────────────────────────────────────────────────────────────
# compose.vault.yml — SecretOps for a standalone Olympus checkout.
#
# On the Cerulean platform you do NOT need this file. Vault already runs there
# as `cerulean-vault`, so consume it instead:
#
#   VAULT_ADDR=http://<host>:8200
#   VAULT_TOKEN_FILE=./data/vault/token/olympus.token   # scoped, never root
#   VAULT_PREFIX=cerulean
#
# and reference secrets as `vault://<mount>/<path>#<key>` — the same convention
# Cerulean resolves at startup, so the stack and the platform agree on one
# format. Point VAULT_TOKEN at a token scoped to this stack's own path under
# that prefix (the `olympus` policy, never the platform's mount-wide one); never
# use the root token, which lives in ./data/vault/init/init.json (0600).
#
# This file is the fallback for a checkout with no platform Vault:
#
#   docker compose -f compose.vault.yml --profile vault up -d
#   export VAULT_ADDR=http://127.0.0.1:8200
#   export VAULT_TOKEN=<the VAULT_DEV_ROOT_TOKEN_ID below>
#   python3 scripts/vault-bootstrap.py
#
# ⚠ It runs Vault in **dev mode**: in-memory storage, auto-initialised and
# auto-unsealed. That is fine for local iteration and NOT for anything whose
# secrets must survive a restart — dev mode loses everything when the container
# is recreated, and its root token is a fixed, well-known string. For durable
# storage use the platform's file-backed Vault (see docs/stack.md).
