Clerk Multi-Environment Setup
Overview
Configure Clerk across development, staging, and production environments with separate instances, environment-aware configuration, and safe promotion workflows.
Prerequisites
- Clerk account (one instance per environment recommended)
- CI/CD pipeline (GitHub Actions, Vercel, etc.)
- Environment variable management in place
Instructions
Step 1: Create Clerk Instances
Create separate Clerk instances in the Dashboard for each environment:
| Environment | Instance | Key Prefix | Domain |
|---|---|---|---|
| Development | my-app-dev | pk_test_ / sk_test_ | localhost:3000 |
| Staging | my-app-staging | pk_test_ / sk_test_ | staging.myapp.com |
| Production | my-app-prod | pk_live_ / sk_live_ | myapp.com |
Step 2: Environment Configuration Files
# .env.local (development - git-ignored)
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_dev...
CLERK_SECRET_KEY=sk_test_dev...
CLERK_WEBHOOK_SECRET=whsec_dev...
# .env.staging (staging)
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_staging...
CLERK_SECRET_KEY=sk_test_staging...
CLERK_WEBHOOK_SECRET=whsec_staging...
# .env.production (production)
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_live_prod...
CLERK_SECRET_KEY=sk_live_prod...
CLERK_WEBHOOK_SECRET=whsec_prod...
Step 3: Environment-Aware Configuration
// lib/clerk-config.ts
type ClerkEnv = 'development' | 'staging' | 'production'
function getClerkEnv(): ClerkEnv {
const key = process.env.NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY || ''
if (key.startsWith('pk_live_')) return 'production'
if (process.env.VERCEL_ENV === 'preview') return 'staging'
return 'development'
}
export const clerkConfig = {
env: getClerkEnv(),
get isDev() { return this.env === 'development' },
get isProd() { return this.env === 'production' },
signInUrl: '/sign-in',
signUpUrl: '/sign-up',
afterSignInUrl: '/dashboard',
get allowedRedirectOrigins() {
switch (this.env) {
case 'production': return ['https://myapp.com']
case 'staging': return ['https://staging.myapp.com']
default: return ['http://localhost:3000']
}
},
}
