Profiles

What Are Profiles?

Profiles are named configurations that define how secrets behave in different environments. They specify which secrets are required vs optional, provide safe defaults for development, and enforce strict requirements for production.

A key feature of profiles is inheritance: non-default profiles inherit secrets from the default profile when it exists. This means you only need to override the specific properties that change between related environments. SecretSpec 0.19+ also lets an unrelated profile opt out and remain standalone.

If a manifest omits default, callers must select an existing profile with --profile, SECRETSPEC_PROFILE, or their user config; the final fallback name is still default.

Basic Usage

Define profiles in your secretspec.toml:

[profiles.default]DATABASE_URL = { description = "PostgreSQL connection", required = true }API_KEY = { description = "External API key", required = true }
[profiles.development]# Inherits DATABASE_URL and API_KEY from default, only overriding their requirementsDATABASE_URL = { required = false, default = "postgresql://localhost:5432/myapp_dev" }API_KEY = { required = false, default = "dev-key-12345" }DEBUG = { description = "Enable debug mode", required = false, default = "true" }
[profiles.production]# Inherits all secrets from default profile# Only need to add production-specific secretsSENTRY_DSN = { description = "Error tracking", required = true }

Selecting Profiles

SecretSpec resolves the active profile in this order:

  1. Command line: --profile production (highest priority)
  2. Environment variable: SECRETSPEC_PROFILE=staging
  3. User config: Default profile in ~/.config/secretspec/config.toml
  4. Fallback: default profile
# Use specific profile$ secretspec check --profile development✓ DATABASE_URL - PostgreSQL connection (using default)✓ API_KEY - External API key (using default)
# Set via environment$ export SECRETSPEC_PROFILE=production
$ secretspec run -- npm start

Profile Inheritance in Detail

When using profiles, inheritance works as follows:

  1. Base definition in default: Define all your secrets with their descriptions and base requirements in the default profile
  2. Override only what changes: Other profiles only need to specify the properties that differ from default
  3. Field-level overrides: Most explicitly set properties replace the corresponding property from default, while omitted properties continue to inherit
  4. Profile-specific secrets: Secrets not in the default profile can be added to any profile

Standalone profiles

Set inherit = false in a non-default profile’s defaults table when its secret set is unrelated to [profiles.default]:

[profiles.default]DATABASE_URL = { description = "Development database", default = "sqlite://./dev.db" }API_KEY = { description = "Development API key" }
[profiles.production]# Inherits both default declarations and overrides only what changes.DATABASE_URL = { required = true }
[profiles.deployment.defaults]inherit = false # SecretSpec 0.19+
[profiles.deployment]# Does not inherit DATABASE_URL, API_KEY, or any of their fields.DEPLOY_TOKEN = { description = "Deployment credential", required = true }

The setting disables both automatic inclusion of default secrets and field-by-field inheritance for secrets explicitly redeclared in the standalone profile. Omitting it preserves the existing inheritance behavior. A standalone profile must declare at least one secret.

Switching reference models

Legacy ref and provider-scoped refs are alternative forms of one inherited address-model setting. Declaring either one in a profile replaces both forms from [profiles.default]; omitting both continues to inherit the default profile’s form. This lets a profile switch from one route-wide address to provider-specific addresses without retaining an invalid mixture of both:

[providers]legacy = "onepassword://Legacy"production = "onepassword://Production"
[profiles.default]API_KEY = { description = "API key", providers = ["legacy"], ref = { item = "shared-api", field = "token" } }
[profiles.production]# Inherits the description, but replaces providers and the complete ref/refs choice.API_KEY = { providers = ["production"], refs = { production = { item = "production-api", field = "credential" } } }

The reverse switch also works: a profile’s ref replaces inherited refs. Within one effective secret, ref and refs remain mutually exclusive. See Secret References for how each model addresses providers.

Profiles, Scopes, Providers, and Extends

These features solve different dimensions of a configuration:

  • A profile chooses an environment or context. It controls requiredness, defaults, provider routes, references, and the {profile} storage namespace.
  • A scope selects which secrets one service or task receives from the effective profile. It does not create another environment.
  • A secret’s providers choose where its value is read and written. Provider chains are also the least-privilege boundary: a process only needs access to the stores used by the secrets in its scope.
  • extends merges separate secretspec.toml files. Use it to share manifests across projects, not to express relationships among several profiles in one small manifest.

For an application with development and production environments plus app, public, and deploy consumers, profiles normally model the two environments, scopes model the three consumers, and per-secret provider chains route each value to the appropriate store.

Profile-Level Defaults

To reduce repetition when multiple secrets in a profile share the same settings, use the profiles.\<name\>.defaults section:

[providers]prod_vault = "onepassword://Production"keyring = "keyring://"
[profiles.production.defaults]providers = ["prod_vault", "keyring"]required = true
[profiles.production]DATABASE_URL = { description = "Production DB" }API_KEY = { description = "API Key" }SENTRY_DSN = { description = "Error tracking" }

Profile defaults apply to all secrets in that profile unless explicitly overridden. In SecretSpec 0.19+, the same table accepts inherit = false to make a non-default profile standalone; unlike required, default, and providers, this controls the relationship with [profiles.default] rather than supplying a value to each secret. The precedence order is:

  1. Secret-level configuration (highest priority) — explicit settings in the secret definition
  2. Profile defaults — from profiles.\<name\>.defaults
  3. Profile inheritance — inherited from default profile
  4. Global defaults (lowest priority) — from CLI, environment, or global config

This is particularly useful for setting common provider fallback routes, requirements, or defaults across all secrets in a profile.

Practical Example

A web application with different requirements per environment:

[project]name = "web-app"revision = "1.0"
[profiles.default]DATABASE_URL = { description = "PostgreSQL connection", required = true }REDIS_URL = { description = "Redis for caching", required = true }JWT_SECRET = { description = "JWT signing key", required = true }
[profiles.development]# Inherits all secrets from default, just adding defaultsDATABASE_URL = { default = "postgresql://localhost:5432/webapp_dev" }REDIS_URL = { default = "redis://localhost:6379/0" }JWT_SECRET = { default = "dev-secret-change-in-prod" }HOT_RELOAD = { description = "Enable hot reload", required = false, default = "true" }
[profiles.production]# Inherits DATABASE_URL, REDIS_URL, JWT_SECRET from default# Only adds production-specific secretsSENTRY_DSN = { description = "Error tracking", required = true }SSL_CERT = { description = "SSL certificate path", required = true }
