Overview
This AMI runs a single-node secrets management store on Ubuntu 24.04 LTS: a key/value store for passwords, API keys and other secrets, reached over HTTPS with a token-based login and policies. The vendor image is pinned to release 2.7.2 and baked into the AMI, so first start does not depend on a registry. Secret data is kept on the instance's disk under Raft storage.
What Perimattic adds
During first-login setup, before the site is published, the store is initialised with 5 key shares (any 3 unseal it) and unsealed once; the root token and all 5 unseal keys are generated on your server and written only to a root-only access file, with a clear warning that they cannot be recovered if lost. A separate administrator account is created with a random 24-character password. The initialisation endpoint is closed at the Apache layer and refused a second time by the store itself, so a stranger cannot initialise or unseal it after setup. Apache provides HTTPS with a free Let's Encrypt certificate.
Limits you should know
The store reseals itself on every restart or reboot and stays sealed, refusing every request, until someone runs the unseal helper with the saved key shares or enters 3 of them in the web interface; there is no automatic unseal. This is one node with local Raft storage: no clustering and no cloud auto-unseal are configured. No audit device is enabled by default. Storage is on the root volume: size it for your secret volume and back it up with EBS snapshots. The application used under 150 MB of memory in our tests, so t3.small is a comfortable starting size.

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) Read the user name, password, root token and 5 unseal keys at the end of setup (or in /opt/app/access.txt) Sign in at https://your-domain/ui/ and store your own secrets under the secret/ path After a reboot, unseal with: sudo bash /opt/app/unseal.sh
A domain name with an A record pointing at the instance is required, because the site is served over HTTPS.
This AMI is built and supported by Perimattic.

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.
Version release notes
Initial release.
- Application: Open-Source Secrets Manager 2.7.2 (container image pinned, baked into the AMI).
- Base: Ubuntu 24.04 LTS, fully patched at build time, built by an automated EC2 Image Builder pipeline.
- TLS: Apache reverse proxy with a Let's Encrypt certificate requested by certbot at first login.
- Credentials are generated on the instance at first login; none are present in the image.
- The store is initialised and unsealed once during setup, before the site is published; the root token and 5 unseal keys are generated on your server and kept root-only, a separate administrator account is created with a random 24-character password, and the initialisation endpoint is closed so a stranger cannot initialise or unseal it afterwards.
- Secrets management 2.7.2 (MPL-2.0, unmodified vendor image) with Raft storage and a web UI, listening on the loopback interface behind Apache.
- The store reseals on every reboot with no automatic unseal; no audit device is enabled by default.
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 starting size: the store used under 150 MB in our tests; the rest is the operating system, Docker and Apache.
-
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 Open-Source Secrets Manager
-
Point a domain at the instance
Create a DNS A record (for example secrets.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
- Initialises the store with 5 unseal key shares (3 needed) and unsealed it once, keeping the root token and all key shares root-only on this server
- Creates an administrator account with a random 24-character password and a matching policy
- Closes the initialisation endpoint at the Apache layer (the store itself also refuses a second initialisation)
- Configures Apache as an HTTPS reverse proxy and requests a Let's Encrypt certificate
- Prints the URL, username, password, root token and unseal keys; 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 Open-Source Secrets Manager
Open https://<your-domain>/ui/ and sign in as admin with the password printed at the end of setup (view it again with: sudo cat /opt/app/access.txt). The store reseals on every reboot: unseal it with sudo bash /opt/app/unseal.sh, or by entering 3 of the 5 saved unseal keys in the web UI.
-
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
Secret data (Raft storage) is in /opt/app/data on the root volume; back it up with EBS snapshots. This is a single node with no clustering and no automatic unseal. No audit device is enabled by default.
