Deploy agentmemory on Railway

This template runs agentmemory on a single Railway service with a persistent volume mounted at /data. The HMAC secret is generated on first boot and persisted to the volume — you read it once from the deploy logs and copy it into your client.

What you get

• A public HTTPS endpoint serving the agentmemory REST API on port 3111
• A persistent Railway Volume at /data for memories, BM25 index, and stream backlog
• Railway 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.
• The deploy uses requiredMountPath: /data so Railway refuses to start the service if no volume is attached at that path — first deploy must create the volume from the dashboard.

Deploy via Railway dashboard

1. Click Deploy from GitHub in the Railway dashboard and pick the rohitg00/agentmemory repo.
2. Set the Config-as-Code Path under the service Settings to deploy/railway/railway.json. Railway picks up the Dockerfile path from there.
3. Open the service's Volumes tab and add a volume mounted at /data (Railway volumes are configured in the dashboard or via railway volume add, not in railway.json).
4. Click Deploy.

Deploy via Railway CLI

# Install: https://docs.railway.com/guides/cli
railway login
railway init                                            # link a new project
railway up --service agentmemory                        # builds + deploys
railway volume add --service agentmemory --mount /data  # attach persistent volume
railway redeploy                                        # restart with the volume

Capture the HMAC secret

After the first deploy succeeds, open the service's Deploy Logs:

railway logs --service agentmemory | grep 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://<your-service>.up.railway.app/agentmemory/livez
# {"status":"ok"}

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

Viewer access (port 3113 stays internal)

Railway only exposes the single public port from your service's PORT env var (which we map to 3111). The viewer stays bound to localhost inside the container. railway ssh is an interactive shell only — it does not support -L-style port forwarding, so reach the viewer with one of the following.

Quick in-container check:

railway ssh --service agentmemory
# inside the container:
curl http://localhost:3113

Browser session — option A (TCP Proxy, recommended): in the Railway dashboard, open the service's Settings → Networking tab and add a TCP Proxy for container port 3113. Railway returns a public host/port pair you can hit directly from your browser. Pair it with the HMAC bearer-auth header so the viewer is not anonymously reachable.

Browser session — option B (in-container sshd): add an openssh-server process to the image and start it from entrypoint.sh on a fixed port, expose that port through a second Railway TCP Proxy, then use a native ssh -L 3113:localhost:3113 <proxy-host> -p <proxy-port> from your laptop. This is the heavier path; option A is what most users will want.

Rotate the HMAC secret

railway ssh --service agentmemory
rm /data/.hmac
exit
railway redeploy --service agentmemory
railway logs --service agentmemory | grep AGENTMEMORY_SECRET=

Update every client with the new secret. Old tokens stop working immediately.

Back up /data

railway ssh --service agentmemory -- "tar czf - /data" > agentmemory-$(date +%Y%m%d).tar.gz

To restore on a fresh volume:

cat agentmemory-YYYYMMDD.tar.gz | railway ssh --service agentmemory -- "tar xzf - -C /"
railway redeploy --service agentmemory

Cost floor and egress

• Hobby plan: $5/month flat, includes $5 of usage.
• agentmemory at idle plus a 1 GB volume typically uses $3–$6 of usage per month on the smallest instance, so most users stay near the $5 floor.
• Egress: $0.10/GB after the bundled allowance.

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

Known caveats

• Railway volumes do not auto-snapshot. Take your own backups (above) or use the dashboard's manual snapshot feature.
• The Dockerfile builds on Railway's builder on every deploy. First deploy is ~2 minutes; cached layers make subsequent rebuilds quick. Pin AGENTMEMORY_VERSION / III_VERSION build args in the service's Variables tab to lock a specific release.
