Glean Multi-Environment Setup

Overview

Glean enterprise search requires environment isolation to prevent test data from polluting production search results. Each environment uses its own datasource names, API tokens, and connector configurations. Sandbox indexes synthetic test documents, staging indexes a curated subset of real documents for search quality validation, and production indexes the full corpus. Connector changes must be tested in staging before promotion to avoid breaking search relevance for end users.

Environment Configuration

const gleanConfig = (env: string) => ({
  development: {
    apiToken: process.env.GLEAN_API_TOKEN_DEV!, baseUrl: "https://sandbox.glean.com/api/v1",
    datasourceSuffix: "_sandbox", indexingEnabled: true, searchQualityChecks: false,
  },
  staging: {
    apiToken: process.env.GLEAN_API_TOKEN_STG!, baseUrl: "https://staging.glean.com/api/v1",
    datasourceSuffix: "_staging", indexingEnabled: true, searchQualityChecks: true,
  },
  production: {
    apiToken: process.env.GLEAN_API_TOKEN_PROD!, baseUrl: "https://app.glean.com/api/v1",
    datasourceSuffix: "_prod", indexingEnabled: true, searchQualityChecks: false,
  },
}[env]);

Environment Files

# Per-env files: .env.development, .env.staging, .env.production
GLEAN_API_TOKEN_{DEV|STG|PROD}=<token>
GLEAN_BASE_URL=https://{sandbox|staging|app}.glean.com/api/v1
GLEAN_DATASOURCE_SUFFIX={_sandbox|_staging|_prod}
GLEAN_INSTANCE={sandbox|staging|production}

Environment Validation

function validateGleanEnv(env: string): void {
  const suffix = { development: "_DEV", staging: "_STG", production: "_PROD" }[env];
  const required = [`GLEAN_API_TOKEN${suffix}`, "GLEAN_BASE_URL", "GLEAN_INSTANCE"];
  const missing = required.filter((k) => !process.env[k]);
  if (missing.length) throw new Error(`Missing Glean env vars for ${env}: ${missing.join(", ")}`);
}

Promotion Workflow

# 1. Index test documents in sandbox
curl -X POST "$GLEAN_BASE_URL/indexing/datasources/wiki_sandbox/documents" \
  -H "Authorization: Bearer $GLEAN_API_TOKEN_DEV" -d @test-docs.json

# 2. Validate search quality in staging
curl "$GLEAN_BASE_URL/search" -H "Authorization: Bearer $GLEAN_API_TOKEN_STG" \
  -d '{"query": "onboarding guide"}' | jq '.results[:3].title'

# 3. Compare relevance scores against baseline
node scripts/compare-search-quality.js --env staging --baseline baseline.json

# 4. Promote connector config to production
cp connectors/staging/*.json connectors/production/
curl -X POST "$GLEAN_BASE_URL/indexing/datasources/wiki_prod/crawl" \
  -H "Authorization: Bearer $GLEAN_API_TOKEN_PROD"

Environment Matrix

Setting	Dev (Sandbox)	Staging	Prod
Data Source	Synthetic test docs	Subset of real docs	Full document index
Datasource Suffix	_sandbox	_staging	_prod
Connectors	Mock connectors	Real connectors	Real connectors
User Access	Developers only	QA + developers	All employees
Crawl Frequency	Manual	Daily	Continuous

Error Handling

Issue	Cause	Fix
Datasource not found	Suffix mismatch between env and config	Verify GLEAN_DATASOURCE_SUFFIX matches connector registration
401 on indexing API	Token scoped to wrong instance	Regenerate token in the correct Glean admin console
Search returns stale results	Crawl not triggered after promotion	Manually trigger crawl via indexing API
Connector sync fails	OAuth credentials expired for data source	Re-authorize connector in Glean admin for the target env
Staging indexes prod data	Connector config copied without suffix update	Always update datasource names when promoting configs
