# Glean Deploy Integration

## Overview

Deploy a containerized Glean enterprise search integration service with Docker. This skill covers building a production image that connects to Glean's Indexing and Search APIs for managing document ingestion, custom datasource connectors, and search queries. Includes environment configuration for multi-datasource indexing, health checks that verify API connectivity and indexing status, and rolling update strategies that avoid interrupting active indexing jobs.

## Docker Configuration

```dockerfile
FROM node:20-slim AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY tsconfig.json ./
COPY src/ ./src/
RUN npm run build

FROM node:20-slim
RUN addgroup --system app && adduser --system --ingroup app app
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
COPY package*.json ./
USER app
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=5s --retries=3 \
  CMD curl -f http://localhost:3000/health || exit 1
CMD ["node", "dist/index.js"]
```

## Environment Variables

```bash
export GLEAN_API_KEY="glean_xxxxxxxxxxxx"
export GLEAN_BASE_URL="https://company-be.glean.com/api/index/v1"
export GLEAN_DATASOURCE="custom-wiki"
export GLEAN_DOMAIN="company-be.glean.com"
export LOG_LEVEL="info"
export PORT="3000"
export NODE_ENV="production"
```

## Health Check Endpoint

```typescript
import express from 'express';

const app = express();

app.get('/health', async (req, res) => {
  try {
    const response = await fetch(`https://${process.env.GLEAN_DOMAIN}/api/index/v1/getdatasourceconfig`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.GLEAN_API_KEY}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ datasource: process.env.GLEAN_DATASOURCE }),
    });
    if (!response.ok) throw new Error(`Glean API returned ${response.status}`);
    res.json({ status: 'healthy', service: 'glean-integration', datasource: process.env.GLEAN_DATASOURCE, timestamp: new Date().toISOString() });
  } catch (error) {
    res.status(503).json({ status: 'unhealthy', error: (error as Error).message });
  }
});
```

## Deployment Steps

### Step 1: Build

```bash
docker build -t glean-integration:latest .
```

### Step 2: Run

```bash
docker run -d --name glean-integration \
  -p 3000:3000 \
  -e GLEAN_API_KEY -e GLEAN_BASE_URL -e GLEAN_DATASOURCE -e GLEAN_DOMAIN \
  glean-integration:latest
```

### Step 3: Verify

```bash
curl -s http://localhost:3000/health | jq .
```

### Step 4: Rolling Update

```bash
docker build -t glean-integration:v2 . && \
docker stop glean-integration && \
docker rm glean-integration && \
docker run -d --name glean-integration -p 3000:3000 \
  -e GLEAN_API_KEY -e GLEAN_BASE_URL -e GLEAN_DATASOURCE -e GLEAN_DOMAIN \
  glean-integration:v2
```

## Error Handling

| Issue | Cause | Fix |
|-------|-------|-----|
| `401 Unauthorized` | Invalid indexing token | Regenerate token in Glean admin under Custom Connectors |
| `403 Forbidden` | Datasource not registered | Create datasource in Glean admin before indexing |
| `400 Bad Request` | Malformed document payload | Validate document schema against Glean Indexing API spec |
| `429 Rate Limited` | Exceeding indexing rate limits | Batch documents (max 100 per request) and add backoff |
| Stale search results | Connector not running on schedule | Verify cron schedule or Cloud Scheduler job status |
