Required top-level keys: credentials, secrets

Environment variables

Every configuration key can be set via an environment variable. Ory Talos converts dot-separated config paths to uppercase with underscores:

<SECTION>_<KEY>

Replace dots (.) with underscores (_) and convert to uppercase. For example, serve.http.port becomes SERVE_HTTP_PORT.

Array values

For array-typed config keys (like secrets.hmac.retired), use comma separation or indexed variables:

# Comma-separated

export SECRETS_HMAC_RETIRED="old-secret-1,old-secret-2"

# Or indexed

export SECRETS_HMAC_RETIRED_0="old-secret-1"

export SECRETS_HMAC_RETIRED_1="old-secret-2"

Precedence

Configuration sources are applied in this order (highest priority first):

  1. Environment variables
  2. Configuration file (--config flag)
  3. Default values

Environment variables always override file-based configuration.

Required variables

At minimum, these must be set (via env var or config file):

SECRETS_HMAC_CURRENT HMAC secret (also derives the pagination cursor key). Minimum 32 characters.
CREDENTIALS_ISSUER Token issuer (iss claim) for derived tokens.
