Documenso Deploy Integration

Overview

Deploy Documenso-integrated applications and self-hosted Documenso instances to Docker, Kubernetes, serverless, and cloud platforms. Covers both app deployment (your code that uses the Documenso API) and self-hosted Documenso deployment.

Prerequisites

• Application ready for deployment
• Cloud platform account (AWS, GCP, Azure)
• Docker installed locally
• Completed documenso-multi-env-setup

Instructions

Step 1: Dockerize Your Documenso Integration

# Dockerfile
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM node:20-alpine AS runtime
WORKDIR /app
RUN addgroup -S app && adduser -S app -G app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/package.json .
USER app
EXPOSE 3000
CMD ["node", "dist/server.js"]
# Note: DOCUMENSO_API_KEY injected at runtime, never baked into image

Step 2: Self-Hosted Documenso (Docker Compose)

# docker-compose.prod.yml
services:
  documenso:
    image: documenso/documenso:latest
    ports:
      - "3000:3000"
    environment:
      - NEXTAUTH_URL=https://sign.yourcompany.com
      - NEXTAUTH_SECRET=${NEXTAUTH_SECRET}   # openssl rand -hex 32
      - NEXT_PRIVATE_ENCRYPTION_KEY=${ENCRYPTION_KEY}
      - NEXT_PRIVATE_ENCRYPTION_SECONDARY_KEY=${ENCRYPTION_SECONDARY_KEY}
      - NEXT_PUBLIC_WEBAPP_URL=https://sign.yourcompany.com
      - NEXT_PRIVATE_DATABASE_URL=postgresql://documenso:${DB_PASS}@db:5432/documenso
      - NEXT_PRIVATE_DIRECT_DATABASE_URL=postgresql://documenso:${DB_PASS}@db:5432/documenso
      # SMTP
      - NEXT_PRIVATE_SMTP_TRANSPORT=smtp-auth
      - NEXT_PRIVATE_SMTP_HOST=${SMTP_HOST}
      - NEXT_PRIVATE_SMTP_PORT=587
      - NEXT_PRIVATE_SMTP_USERNAME=${SMTP_USER}
      - NEXT_PRIVATE_SMTP_PASSWORD=${SMTP_PASS}
      - NEXT_PRIVATE_SMTP_FROM_ADDRESS=signing@yourcompany.com
      - NEXT_PRIVATE_SMTP_FROM_NAME=YourCompany Signing
      # Signing certificate
      - NEXT_PRIVATE_SIGNING_PASSPHRASE=${CERT_PASSPHRASE}
    volumes:
      - ./certs/signing-cert.p12:/opt/documenso/cert.p12:ro
    depends_on:
      db:
        condition: service_healthy
    restart: unless-stopped

  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: documenso
      POSTGRES_PASSWORD: ${DB_PASS}
      POSTGRES_DB: documenso
    volumes:
      - pgdata:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U documenso"]
      interval: 5s
      retries: 5

volumes:
  pgdata:

Important notes:

• Documenso container runs as non-root (UID 1001) -- ensure mounted files are readable
• Prisma migrations run automatically on container start
• Documents are stored in PostgreSQL by default (fine for small-to-medium deployments)
• Use a reverse proxy (nginx, Caddy, Traefik) for SSL termination

Step 3: AWS Lambda (API Integration)

// lambda/signing-handler.ts
import { Documenso } from "@documenso/sdk-typescript";
import { SecretsManager } from "@aws-sdk/client-secrets-manager";

const sm = new SecretsManager({ region: "us-east-1" });
let client: Documenso;

async function getClient(): Promise<Documenso> {
  if (!client) {
    const secret = await sm.getSecretValue({ SecretId: "documenso/api-key" });
    client = new Documenso({ apiKey: JSON.parse(secret.SecretString!).apiKey });
  }
  return client;
}

export async function handler(event: any) {
  const documenso = await getClient();
  const { title, signerEmail, signerName } = JSON.parse(event.body);

  const doc = await documenso.documents.createV0({ title });
  await documenso.documentsRecipients.createV0(doc.documentId, {
    email: signerEmail,
    name: signerName,
    role: "SIGNER",
  });
  await documenso.documents.sendV0(doc.documentId);

  return {
    statusCode: 200,
    body: JSON.stringify({ documentId: doc.documentId }),
  };
}

Step 4: Google Cloud Run

# Store secret
echo -n "$DOCUMENSO_API_KEY" | gcloud secrets create documenso-api-key --data-file=-

# Deploy
gcloud run deploy signing-service \
  --image gcr.io/$PROJECT_ID/signing-service \
  --platform managed \
  --region us-central1 \
  --set-secrets DOCUMENSO_API_KEY=documenso-api-key:latest \
  --memory 256Mi \
  --timeout 30s

Step 5: Health Check Endpoint

// src/health.ts — include in every deployment
app.get("/health", async (req, res) => {
  try {
    const client = new Documenso({ apiKey: process.env.DOCUMENSO_API_KEY! });
    await client.documents.findV0({ page: 1, perPage: 1 });
    res.json({ status: "healthy", service: "documenso" });
  } catch (err: any) {
    res.status(503).json({
      status: "unhealthy",
      service: "documenso",
      error: err.message,
    });
  }
});

Deployment Checklist

• API keys stored in secret manager (not env files)
• Health check endpoint configured
• HTTPS enforced (required for webhooks)
• Self-hosted: signing certificate mounted
• Self-hosted: secrets generated with openssl rand -hex 32
• Reverse proxy handles SSL termination
• Container runs as non-root user
• Monitoring and alerting configured
