Deploy agentmemory on Render

This template runs agentmemory on a single Render Web Service with a persistent disk mounted at /data. The HMAC secret is generated on first boot and persisted to the disk — you capture it from the deploy logs exactly once.

What you get

  • A public HTTPS endpoint serving the agentmemory REST API on port 3111 (Render injects PORT defaulting to 10000; we override it to 3111 via envVars so the published port matches the container's bind)
  • A 1 GB persistent disk at /data for memories, BM25 index, and stream backlog
  • Render healthcheck against /agentmemory/livez
  • The HMAC bearer secret is generated on first boot inside the container and persisted to /data/.hmac (chmod 600); the operator copies it from the deploy logs once.

Deploy via Render Blueprint

Render's one-click deploy button only auto-detects render.yaml at the repository root, which the agentmemory repo keeps clean. Use the dashboard's manual Blueprint flow instead:

  1. Push the deploy/render/ directory to a Git provider Render can reach (a fork of rohitg00/agentmemory works).
  2. In the Render dashboard, click New + → Blueprint.
  3. Point Render at the repo and the path deploy/render/render.yaml.
  4. Render reads the Blueprint, provisions the disk, builds the Dockerfile, and starts the service. The whole flow takes 3–5 minutes on the first run.

Deploy via Render Deploy Hook (one-click)

Once the Blueprint exists in your account, generate a Deploy Hook URL in the service settings. Future deploys are a single curl call:

curl "https://api.render.com/deploy/srv-XXYYZZ?key=AABBCC"

To pin a specific @agentmemory/agentmemory release, set the AGENTMEMORY_VERSION build arg in the service's Environment tab before the next deploy. Same for III_VERSION.

Capture the HMAC secret

After the first deploy succeeds, open the service's Logs tab and search for AGENTMEMORY_SECRET=. You will see exactly one line of the form AGENTMEMORY_SECRET=<64 hex chars>. Copy it into your client environment. The secret is never printed again on subsequent boots.

Verify the deployment

curl https://agentmemory.onrender.com/agentmemory/livez
# {"status":"ok"}

For an authenticated call, your client must send Authorization: Bearer <secret>.

Viewer access (port 3113 stays internal)

Render only exposes one public port per service, and we use it for 3111. The viewer port stays bound to localhost inside the container. Reach it via Render's SSH:

# Settings → SSH → enable for your service, copy the connection command
ssh srv-XXYYZZ@ssh.<region>.render.com -L 3113:localhost:3113
# now http://localhost:3113 in your browser hits the in-container viewer

Rotate the HMAC secret

ssh srv-XXYYZZ@ssh.<region>.render.com
rm /data/.hmac
exit
# trigger a redeploy from the Render dashboard or via the Deploy Hook

After the redeploy, grab the new secret from the logs and update every client. Old tokens stop working immediately.

Back up /data

ssh srv-XXYYZZ@ssh.<region>.render.com "tar czf - /data" > agentmemory-$(date +%Y%m%d).tar.gz

Render also takes daily snapshots of persistent disks automatically on paid plans — the SSH tarball is a belt-and-braces option you can ship off-platform.

Cost floor and egress

  • Starter plan web service: $7/month (0.5 CPU, 512 MB RAM).
  • 1 GB persistent disk: $0.25/GB/month, so $0.25/month for the default.
  • Bandwidth: 100 GB outbound included, then $0.10/GB.

See https://render.com/pricing for the current rate card.

Known caveats

  • Render Free tier does not support persistent disks. The Starter plan ($7/month) is the minimum.
  • Render restarts the service on every deploy. The HMAC secret survives because it lives on the disk, but expect a 10–30 s gap of 502s during rollouts.
  • Render runs amd64 only for web services. The Dockerfile selects the matching iii binary automatically via uname -m.
