How to Deploy Docassemble Securely on AWS: Complete DevOps Checklist

Introduction

Deploying Docassemble on AWS is easy to begin and easy to get wrong. A production legal application must protect client records, uploaded evidence, generated documents, credentials, and sessions.

To deploy Docassemble on AWS securely, separate compute from persistent data, use private networks, encrypt data paths, centralize secrets, and prove backups can be restored. This checklist is for US legal organizations and technology teams.

 Your organization remains responsible for configuration, application controls, data governance, and legal obligations. “Hosted on AWS” does not automatically mean compliant.

What Is a Secure Docassemble AWS Deployment?

Docassemble is an open-source platform for guided interviews, document assembly, workflow logic, and form generation. Teams use it for client intake, court forms, eligibility screening, contracts, and administrative processes.

Docassemble is commonly installed with Docker. Its environment may include NGINX, PostgreSQL, Redis, RabbitMQ, Celery workers, scheduled tasks, user uploads, and generated documents. Its scalability guidance explains how web servers can share centralized SQL, Redis, and cloud storage.

A secure production design therefore treats the container as replaceable. Databases, files, configuration, logs, and secrets require deliberate persistence and protection outside the application instance.

Choose the Right Docassemble AWS Deployment Architecture

Secure single-instance hosting

A hardened EC2 instance running Docker can suit an internal tool, controlled pilot, or low-volume workflow. Put an Application Load Balancer (ALB) in public subnets and the EC2 instance in a private subnet. Use Amazon RDS for PostgreSQL, S3 for persistent objects, and Secrets Manager for credentials.

This model is simpler to operate, but the application instance remains a potential availability bottleneck. Define acceptable recovery time before choosing it.

Highly available legal tech infrastructure

Public or business-critical services usually need at least two application instances across Availability Zones, an ALB, Multi-AZ RDS, centralized Redis where supported and tested, shared S3 storage, and automated recovery procedures.

EC2 with Docker follows the conventional Docassemble model. ECS, Fargate, or EKS may work, but first validate background workers, persistent paths, startup, and graceful shutdown.

Layer	Recommended AWS control	Security purpose
Edge	Route 53, ACM, ALB, AWS WAF	TLS, routing, request filtering
Compute	Private EC2 or validated orchestration	Isolate replaceable application workloads
Data	RDS PostgreSQL, S3, optional ElastiCache	Centralize and protect persistent state
Secrets	Secrets Manager and KMS	Remove credentials from images and repositories
Operations	CloudWatch, CloudTrail, GuardDuty, Security Hub	Detect faults and suspicious activity
Recovery	RDS backups, S3 versioning, AWS Backup	Restore data and infrastructure

Complete Secure Docassemble Hosting Checklist

1. Establish account and IAM guardrails

• Require MFA for human administrators and prefer federated, short-lived access.
• Give EC2 tasks or instances IAM roles instead of long-lived access keys.
• Enable CloudTrail across all active Regions and protect its log destination.
• Review permissions regularly; avoid wildcard actions and resources where practical.

The goal is least privilege with traceability: every administrative action should be attributable to a person or workload.

2. Build a private VPC

Place the ALB in public subnets across at least two Availability Zones. Put application instances, RDS, Redis, and other internal services in private subnets. Do not assign public IP addresses to databases or application hosts.

Security groups should allow:

• Internet traffic to the ALB on HTTPS only
• Application traffic only from the ALB security group
• PostgreSQL only from the application security group
• Redis or queue traffic only from approved workloads

Use AWS Systems Manager Session Manager instead of exposing SSH. Add VPC endpoints for AWS services when appropriate.

3. Harden the Docassemble container and host

Pin a tested image version or immutable digest. Scan dependencies, patch the host OS, remove unnecessary packages, and restrict Docker socket access.

Use application health checks and resource limits. Centralize logs without recording answers, document contents, tokens, passwords, or unnecessary personal data. Test interviews, PDF generation, email, jobs, authentication, and rollback in staging.

4. Protect config.yml and application secrets

Docassemble reads system settings from /usr/share/docassemble/config/config.yml. Its documentation notes that an S3-backed setup may copy this file from the bucket during startup. Treat that cloud copy as authoritative configuration: encrypt it, version it, restrict access, and monitor changes.

Never commit credentials to Git or bake them into an image. Retrieve them from Secrets Manager through a narrowly scoped IAM role. After rotation, confirm that dependent services reconnect.

5. Secure PostgreSQL, Redis, queues, and storage

Use RDS PostgreSQL in private subnets with encryption at rest, automated backups, deletion protection, and Multi-AZ for critical workloads. Require TLS connections; AWS documents rds.force_ssl=1 as the relevant PostgreSQL control. Monitor connections, storage, CPU, latency, and replication or failover events.

For Redis or messaging, require encryption where available, authentication, private access, and restrictive security groups. Confirm compatibility in staging.

Use S3 Block Public Access, KMS encryption, versioning, lifecycle rules, and narrowly scoped bucket policies for uploads, generated files, backups, and configuration. Avoid one broad bucket policy for every data class.

6. Enforce HTTPS and edge protection

Use an ACM certificate on an HTTPS ALB listener, redirect HTTP to HTTPS, and choose a modern AWS TLS policy. Configure external URL and proxy behavior so secure cookies and redirects work.

Associate AWS WAF with the ALB. Test managed rules in count mode before blocking, and tune rate limits around legitimate uploads and long requests.

Set security headers deliberately, including HSTS after HTTPS is fully validated, content-type protections, an appropriate referrer policy, and a tested Content Security Policy. Cookie settings should include Secure, HttpOnly, and suitable SameSite behavior.

7. Strengthen identity and application access

Require administrator MFA and role-based access for developers, authors, support staff, and auditors. Use SSO where appropriate and review privileged access regularly.

For public interviews, apply data minimization and clear consent language. Expire abandoned sessions, define retention periods for answers and files, and prevent sensitive values from appearing in URLs, analytics platforms, or support screenshots.

8. Centralize monitoring and incident detection

Create CloudWatch dashboards and alarms for:

• ALB 4xx/5xx rates, latency, and unhealthy targets
• Host or task CPU, memory, disk, and restarts
• RDS connections, storage, latency, and failovers
• Queue depth and Celery job failures
• Certificate expiry and WAF rule activity
• Backup failures and unusual authentication events

Enable GuardDuty and aggregate findings in Security Hub. Route actionable alerts to an owned on-call channel with escalation rules.

9. Make backups independently recoverable

Back up PostgreSQL, S3 objects, configuration, custom packages, key dependencies, and infrastructure definitions. Encrypt recovery points and use cross-account or cross-Region copies when justified.

Define two business metrics:

• Recovery Point Objective (RPO): the maximum acceptable data loss
• Recovery Time Objective (RTO): the maximum acceptable outage

Perform restoration drills in isolation. Confirm that interviews, attachments, documents, authentication, workers, and email function. Backups prove copies exist; restore tests prove recoverability.

10. Build a controlled CI/CD release process

Keep infrastructure in version-controlled Terraform, AWS CDK, or CloudFormation. Run secret detection, dependency and container scans, infrastructure-policy checks, and automated tests before deployment. Promote the same immutable artifact from staging to production.

Validate sessions and background jobs before rolling releases. Document rollback for images, configuration, migrations, and packages, and record release approvals.

The Missing Angle: Data Lifecycle Is Part of Cloud Security for Law Firms

Many deployment guides stop after encryption and firewalls. The commonly missed risk is uncontrolled data replication.

Map where legal data travels: browser, ALB, application memory, PostgreSQL, Redis, queues, S3, email, logs, backups, monitoring tools, staging environments, and support exports. For each location, document the data owner, purpose, retention period, access group, deletion method, and recovery implication.

Decide whether deleted client data must disappear immediately or age out under a retention schedule. Test legal holds, access requests, vendor access, and evidence preservation.

Citation-Ready: Minimum Production Baseline for Docassemble on AWS

A production Docassemble AWS deployment should, at minimum, use private application and data subnets; HTTPS through an ALB; no publicly reachable database; encrypted RDS, S3, and backups; TLS for database and cache connections; runtime secret retrieval; least-privilege IAM roles; centralized redacted logs; monitored health and security alerts; immutable, tested releases; and regularly verified restores. High-availability systems also need multiple application instances, centralized state, Multi-AZ data services, and documented failure testing.

This baseline is a starting point, not a compliance certification. Final controls must reflect the data handled, contractual duties, applicable US privacy rules, professional obligations, and the organization’s risk assessment.

Final Takeaway

The safest answer to how to deploy Docassemble AWS secure is not a single command. It is a repeatable operating model: isolate the application, externalize state, encrypt data, restrict access, observe behavior, control releases, minimize retained information, and rehearse recovery.

Start with the production baseline, document exceptions, and make verification part of normal maintenance.

Frequently Asked Questions About Docassemble AWS Deployment

Can Docassemble be deployed securely on AWS?

Yes. A secure design uses private networking, encrypted managed data services, runtime secrets, least-privilege access, monitored workloads, controlled updates, and tested recovery. Security depends on configuration and operations, not the cloud provider’s name alone.

Is one EC2 instance enough for Docassemble?

It may be enough for a pilot or low-volume internal workflow if downtime is acceptable and recovery is tested. Public or critical services generally need redundant application instances and centralized persistent state.

Should Docassemble use RDS instead of its container database?

For most production deployments, RDS improves persistence, backup management, monitoring, encryption, and availability. Migration and compatibility must still be tested before launch.

Does AWS make a Docassemble application compliant?

No. AWS offers services and compliance programs, but the customer remains responsible for configuration, access, data handling, application security, policies, and evidence. Obtain legal or compliance advice for your specific obligations.

How often should a Docassemble deployment be tested?

Continuously test code and configuration in CI/CD, monitor production at all times, patch on a risk-based schedule, scan regularly, and perform restore and incident-response exercises at intervals tied to the system’s risk and RTO/RPO.
