HedgeDoc 1.12.0 (AGPL-3.0) on Ubuntu 24.04: real-time collaborative Markdown notes with live preview and slide mode, behind HTTPS with a generated administrator password and anonymous editing and open sign-up turned off.
Overview
This AMI runs HedgeDoc, a real-time collaborative Markdown editor, on Ubuntu 24.04 LTS. Multiple people edit the same note at once and see each other's changes live, with a side-by-side Markdown preview, syntax highlighting, tables, diagrams and a slide presentation mode. The vendor image is pinned to version 1.12.0 and baked into the AMI, so first start does not depend on a registry. Notes and uploads are kept in a PostgreSQL database and a local folder on the instance.
What Perimattic adds
Closed by default: out of the box HedgeDoc allows anyone to create and edit notes anonymously and anyone to register an account. Here anonymous note creation and anonymous editing are both turned off, new default notes are limited to signed-in users, and email sign-up is closed once the administrator account is created on your server during first-login setup, with a generated 24-character password. Setup checks that the password works, that a wrong password and a stranger's sign-up are refused, and that an anonymous visitor cannot create a note, before the site is published.
HTTPS and live collaboration: Apache is configured as a reverse proxy with websocket support and a free Let's Encrypt certificate from certbot, so the real-time editing connection works the same as it would directly against the application. Gravatar avatars and the public statistics API are turned off.
Limits you should know
Without the administrator's own sign-up turned back on, only the administrator can use the site; sign in and invite others, or re-enable registration from the application settings if you want an open team space. No SMTP server is configured, so email-based password reset is not available until you add one. In our tests the application and database together used well under 350 MB of memory; a t3.small is a comfortable size. Notes and uploads live on the instance: back them up or snapshot the volume before upgrades.
Licence and attribution
Built on the open-source HedgeDoc (AGPL-3.0 licence), unmodified. Not affiliated with, endorsed by, or sponsored by the HedgeDoc project; HedgeDoc is a trademark of its owner.
Getting Started Launch the AMI and open ports 22, 80 and 443 in the security group SSH in and answer the setup prompts (domain and admin email) Open https://your-domain/ and sign in with the admin email and the password printed at the end of setup Create a note, share its link with your team, and watch edits appear live
A domain name with an A record pointing at the instance is required, because the site is served over HTTPS.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Additional details
Usage instructions
-
Launch an Instance
From AWS Marketplace, click Continue to Subscribe and then Continue to Configuration to launch the AMI.
-
Choose the Recommended Instance Type
t3.small (2 GB of memory) is the recommended size: the application and database together used well under 350 MB in our tests.
-
Configure Security Group
Allow inbound traffic on the following ports:
- 22 (SSH) - terminal access for setup
- 80 (HTTP) - needed to validate your domain for the TLS certificate
- 443 (HTTPS) - access to Collaborative Markdown Editor
-
Point a domain at the instance
Create a DNS A record (for example notes.example.com) pointing to the instance's public IP before you log in.
-
Connect to the Instance
ssh -i <your-key.pem> ubuntu@<public-ip>
-
First-Login Setup
The first SSH login runs a guided setup:
- Prompts for your domain and admin email and checks the DNS A record
- Generates a random 24-character administrator password and creates the administrator account on your server
- Starts the application with anonymous note creation and editing off and email sign-up closed, then checks that the password works, a wrong password is refused and an anonymous visitor cannot create a note
- Configures Apache as an HTTPS reverse proxy with websocket support and requests a Let's Encrypt certificate
- Prints the URL, email and password; they are also stored in /opt/app/access.txt (root only)
If a step fails, fix the problem shown and log in again: the setup resumes where it stopped.
-
Access Collaborative Markdown Editor
Open https://<your-domain>/ and sign in with the admin email and the password printed at the end of setup (view it again with: sudo cat /opt/app/access.txt). Turn registration back on from the application's own settings if you want others to create their own accounts.
-
Credentials
Generated on your server, never shared between customers. View them again with:
sudo cat /opt/app/access.txt
-
Manage the Services
cd /opt/app sudo docker compose ps sudo docker compose restart
Notes are kept in PostgreSQL at /opt/app/postgres and uploads in /opt/app/uploads; back them up or snapshot the volume before upgrades. Anonymous visitors cannot create or edit notes.
