Feature Request: Environment-Specific Secrets in Parent Stacks

[alex-y-su]

Problem

Currently, secrets defined in .sc/stacks/<parent-stack>/secrets.yaml are available globally to all environments. This creates challenges:

1. Security: Production secrets (API keys, passwords) shouldn't be accessible in dev/staging
2. Isolation: Some secrets should only exist in specific environments
3. Naming: Same secret name (e.g., DATABASE_PASSWORD) needs different values per environment while services expect a consistent name

Example of the Problem

# Current: .sc/stacks/devops/secrets.yaml
values:
  DATABASE_PASSWORD: "prod-password-123"      # Available everywhere - wrong for dev/staging
  STRIPE_API_KEY: "sk_live_xxx"               # Production key exposed to all envs
  SLACK_WEBHOOK: "https://hooks.slack.com/..." # Maybe OK to share

A developer deploying to staging inadvertently gets access to production secrets.

Proposed Solution

Add a secrets section to server.yaml that controls per-environment secret availability and mapping.

Syntax

# .sc/stacks/devops/server.yaml
schemaVersion: 1.0

secrets:
  inheritAll: false  # Default: true (backwards compatible)
  
  environments:
    staging:
      include:
        # null (~) means "use same key from secrets.yaml"
        SLACK_WEBHOOK: ~
        
        # Reference another key in secrets.yaml
        DATABASE_PASSWORD: "${secret:DATABASE_PASSWORD_STAGING}"
        STRIPE_API_KEY: "${secret:STRIPE_TEST_KEY}"
        
        # Literal value (no ${secret:} wrapper)
        LOG_LEVEL: "debug"
        ENABLE_PROFILING: "true"
    
    production:
      include:
        SLACK_WEBHOOK: ~
        DATABASE_PASSWORD: "${secret:DATABASE_PASSWORD_PROD}"
        STRIPE_API_KEY: "${secret:STRIPE_LIVE_KEY}"
        DATADOG_API_KEY: ~
        LOG_LEVEL: "warn"

resources:
  staging:
    template: stack-per-app
    # ...
  production:
    template: stack-per-app
    # ...

secrets.yaml (encrypted):

values:
  DATABASE_PASSWORD_PROD: "super-secret-prod-password"
  DATABASE_PASSWORD_STAGING: "staging-password-123"
  STRIPE_LIVE_KEY: "sk_live_xxx"
  STRIPE_TEST_KEY: "sk_test_yyy"
  SLACK_WEBHOOK: "https://hooks.slack.com/..."
  DATADOG_API_KEY: "dd-api-xxx"

Syntax Reference

Pattern	Type	Description
SECRET_NAME: ~	Reference	Use value of SECRET_NAME from secrets.yaml
NAME: "${secret:KEY}"	Mapped Reference	Expose as NAME, fetch value from KEY in secrets.yaml
NAME: "value"	Literal	Expose as NAME with hardcoded value

Behavior

Setting	Description
inheritAll: true (default)	All secrets.yaml values available in all envs (current behavior)
inheritAll: false	Only explicitly listed secrets available per environment
exclude: [names]	Block specific secrets (only with inheritAll: true)

Example with Exclusions

secrets:
  inheritAll: true  # Start with all secrets
  
  environments:
    staging:
      exclude:
        - DATADOG_API_KEY      # Not needed in staging
        - STRIPE_LIVE_KEY      # Security: no prod keys in staging
      override:
        STRIPE_API_KEY: "${secret:STRIPE_TEST_KEY}"
    
    production:
      # Gets everything, no overrides needed

Service Usage (No Changes)

Client configurations remain unchanged:

# client.yaml
stacks:
  production:
    parent: company/devops
    secrets:
      DB_PASS: "${secret:DATABASE_PASSWORD}"  # Resolves to prod value
      STRIPE: "${secret:STRIPE_API_KEY}"      # Resolves to live key

# Same client.yaml deployed to staging
stacks:
  staging:
    parent: company/devops
    secrets:
      DB_PASS: "${secret:DATABASE_PASSWORD}"  # Resolves to staging value
      STRIPE: "${secret:STRIPE_API_KEY}"      # Resolves to test key

Validation

sc validate should:

• Warn if a secret referenced in client.yaml isn't available for target environment
• Error if ${secret:KEY} references a non-existent key in secrets.yaml
• Warn about unused secrets in secrets.yaml

Migration

• Backwards compatible: Without secrets section, all secrets available everywhere
• Opt-in: Teams adopt incrementally
• No client changes: Existing service configs work without modification

Benefits

• Secret values stay encrypted in secrets.yaml
• Mapping logic in version-controlled server.yaml
• Supports both references and literals
• No changes to service configurations
• Clear separation of environments
• Backwards compatible

📝 Execution Summary:
I've processed the issue and made the following changes:

I'll analyze the GitHub issue #60 and provide a solution. Let me start by exploring the repository structure and understanding the issue.

Let me explore the parent-stacks examples and related code to understand the current implementation:

Now let me search for the actual code that handles secrets and server.yaml processing:

Let me examine the core server.go and secrets.go files to understand the current implementation:

Now let me check the schema files to understand the current JSON schema:

📝 Execution Summary:
I've processed the issue and made the following changes:

I'll analyze the issue and create the necessary product management documentation for the environment-specific secrets feature. Let me start by understanding the codebase structure and the issue requirements.

Let me read the key secrets management files in smaller chunks and understand the current implementation:

Let me read more files to understand the complete context, including models and placeholder resolution:

Now let me look at the CLI to understand how commands are structured:

Now I have a comprehensive understanding of the codebase. Let me create the product management documentation for this feature. I'll create the necessary documentation files under the correct directory structure.

Let me create the files properly by checking if they exist first:

The files already exist from the previous PM work. Let me read them to understand what was created and verify the content:

I can see that the product management documentation has already been created. Now I need to read the remaining files to understand the complete scope and then provide the handoff JSON for the next role (Architect).

Perfect! I can see that comprehensive product management documentation has already been created. All the required files are in place:

1. requirements.md - Comprehensive product requirements specification
2. task-breakdown.md - Detailed implementation task breakdown with 6 phases and 23 tasks
3. acceptance-criteria.md - Detailed acceptance criteria and test scenarios
4. README.md - Overview document for the PM work
5. .handoff.json - Handoff data for the next role

The documentation is complete and ready for the next phase. Let me verify the file structure and provide the final handoff JSON:

Excellent! All product management documentation has been created successfully. Now I need to provide the final handoff JSON for the sequential workflow to continue to the next role (Architect).
