PDF Signature Tool in Docker: Set It Up in 5 Minutes
DocuSeal runs in containers. No per-seat fees. No envelope limits. Control your document signing infrastructure.
Why Opsily for Your PDF Signature Tool in Docker?
A PDF signature tool in Docker puts control in your hands. Docker ops shouldn't be your burden.
Infrastructure Without the Overhead
We handle the containers, backups, scaling, and security updates. You focus on signing documents. No DevOps team required. No cost overruns from containerization mistakes. Sleep at night knowing your data stays on Hetzner Frankfurt servers in the EU.
GDPR by Default
DocuSeal on Opsily stays in the EU. All data lives on your infrastructure. No US cloud transfer. No Schrems II compliance worries. Audit logs remain on-premise. You control retention. That's the entire difference from DocuSign.
Scale Without Surprise Bills
DocuSeal licenses don't care how many documents you sign. Neither do we. One flat rate covers 3 apps (Small), 5 (Medium), 10 (Large), or unlimited (Unlimited). Add signers, add documents, add workflows. No invoice shock.
Built for teams who need reliability

Docker Compose DocuSeal: 5 Minute Setup
Two commands. One config file. Your PDF signature tool running.
Choose Your App
Select an app to get started.
Clone and Configure
Pull the DocuSeal Docker Compose configuration. Set your database URL, mail server, and secret key in a .env file. 5 environment variables. Done.
Run Containers
docker-compose up -d starts the PostgreSQL database and DocuSeal API. Health checks auto-restart containers. Logs stream to your monitoring tool.
Configure the App
Open the UI in your browser. Add your custom domain behind a reverse proxy (Traefik, nginx). Enable SAML if you need SSO. Set up webhooks to n8n for workflow automation.
Go Live
Start uploading PDFs. Create e-signature workflows. Invite signers via email. DocuSeal handles the rest: form detection, legal validity, audit logging, all on your infrastructure.
EUR 800 a year for tools that used to cost us multiples of that. We replaced HubSpot, Make.com, and our password manager with self-hosted apps on Opsily. One provider, one fee.

Running DocuSeal in Production
Docker Compose is perfect for dev and staging. Production requires a few more steps.
Health Checks and Auto-Restart
Define healthcheck in your compose file: hit /health endpoint every 30 seconds. If the app hangs, Docker restarts the container automatically. No manual intervention.
SSL/TLS Termination
Don't expose DocuSeal directly. Use a reverse proxy (Traefik, nginx, or Caddy) in front of your containers. Let it handle SSL certificates via Let's Encrypt. DocuSeal talks HTTP internally; the proxy handles encryption.
Volume Persistence
DocuSeal stores uploaded PDFs and generated documents in /data/uploads. Mount this to a persistent volume. If the container dies, your documents remain. Back up that volume daily.
Database Backups
PostgreSQL runs in a container too. Set up automated pg_dump to backup the database every 24 hours. Store backups off-host. You own the data; you own the backup responsibility.
Scaling and Load Balancing
One DocuSeal container handles thousands of signings per day. If you need horizontal scaling, run multiple API containers behind a load balancer and point them to the same PostgreSQL database. Opsily handles this. Self-hosted, you manage it.
Environment Parity
Use the same Docker Compose file across dev, staging, and prod. Change only the .env file (domain, database URL, mail server). This eliminates "works on my machine" surprises. Every environment is identical.
Pair DocuSeal With Your Stack
DocuSeal plays well with workflow automation, file storage, and headless CMS tools. All containerized. All self-hosted.
Open-source document signing and e-signature platform
Trust and Compliance Built In
DocuSeal on Opsily meets the strictest data residency and audit requirements.
GDPR Compliant

Audit Logs

Encrypted at Rest
Documents and signing data encrypted using AES-256. Keys stored separately. Even Opsily team cannot read your data.
Legally Binding Signatures
Compliant with eIDAS (EU), ESIGN (US), and major international frameworks. DocuSeal's signatures hold up in court.
Data Residency Control
Hosted on Hetzner Frankfurt. German data protection laws apply. You know exactly where your data lives.

We were paying per user on everything and it added up fast. Now we run five apps for less than one of those old plans. My finance team finally stopped asking questions.

Wanted to use n8n for ages but the self-host part always stopped me. Opsily just handled it. Got the power without becoming an IT person overnight.
