Skill: Configuration Management

Secrets stay secret. Configs are code. Feature flags enable safe rollout.

Secrets Management

Never commit secrets:

# ✗ Don't
export DATABASE_PASSWORD="my-password"
git add .env
git commit

# ✓ Do
export DATABASE_PASSWORD=$(aws secretsmanager get-secret-value ...)
# or
source <(vault kv get -format=json secret/db | jq -r '.data | to_entries | .[] | "\(.key)=\(.value)"')

Tools: Vault, AWS Secrets Manager, Azure Key Vault

Environment Configs

# config/environments.yaml

development:
  database:
    host: localhost:5432
    pool_size: 5
  cache:
    ttl: 60s

production:
  database:
    host: db.prod.example.com:5432
    pool_size: 100
  cache:
    ttl: 3600s

Load by environment:

import yaml
config = yaml.load(open(f'config/{ENV}.yaml'))

Feature Flags

Safe rollout:

feature_auth_v2: enabled for [10%, 25%, 50%, 100%]

if feature_flag("auth_v2"):
    use_new_auth()
else:
    use_old_auth()

Tools: LaunchDarkly, Unleash, custom

Safe Defaults

# ✓ Good defaults
class Config:
    DEBUG = False  # Never debug in production
    TIMEOUT = 30   # Reasonable default
    RETRIES = 3    # Sensible retry count

# ✗ Bad defaults
class Config:
    DEBUG = True   # Oops, left it on
    TIMEOUT = 3600  # Way too long
