Fly.io Deployment

Goal: Run Fased on a Fly.io machine with persistent storage.
Fly is not the default Fased hosting posture. The standard hosted guidance is: use a normal VPS, join it to Tailscale, and keep operator access private through the tailnet. If you want that posture, use Hetzner or GCP instead.
Use Fly only when you intentionally want an internet-facing deployment or a Fly-native edge setup. Do not treat *.fly.dev as the default private operator path.

What you need

  • flyctl CLI installed
  • Fly.io account
  • Gateway token and any model/channel credentials you plan to add later

Beginner quick path

  1. Clone repo → customize deploy/hosting/fly.toml
  2. Create app + volume → set secrets
  3. Deploy with fly deploy -c deploy/hosting/fly.toml
  4. Use fly proxy for Control UI
  5. Finish setup from the Agent tabs

1) Create the Fly app

# Clone the repo
git clone https://github.com/fased-ai/fased.git fased
cd fased

# Create a new Fly app (pick your own name)
fly apps create my-fased

# Create a persistent volume (1GB is usually enough)
fly volumes create fased_data --size 1 --region iad
Tip: Choose a region close to you. Common options: lhr (London), iad (Virginia), sjc (San Jose).

2) Configure fly.toml

Edit deploy/hosting/fly.toml to match your app name and requirements. Security note: The default Fly path exposes a public URL. That is not the standard Fased operator posture. If you need private operator access, prefer a VPS with Tailscale instead of Fly.
app = "my-fased"  # Your app name
primary_region = "iad"

[build]
  dockerfile = "Dockerfile"

[env]
  NODE_ENV = "production"
  FASED_PREFER_PNPM = "1"
  FASED_STATE_DIR = "/data"
  NODE_OPTIONS = "--max-old-space-size=1536"

[processes]
  app = "node dist/index.js gateway --allow-unconfigured --port 3000 --bind lan"

[http_service]
  internal_port = 3000
  force_https = true
  auto_stop_machines = false
  auto_start_machines = true
  min_machines_running = 1
  processes = ["app"]

[[vm]]
  size = "shared-cpu-2x"
  memory = "2048mb"

[mounts]
  source = "fased_data"
  destination = "/data"
Key settings:
SettingWhy
--bind lanBinds to 0.0.0.0 so Fly’s proxy can reach the gateway
--allow-unconfiguredStarts without a config file so the Control UI can write first-run state
internal_port = 3000Must match --port 3000 (or FASED_GATEWAY_PORT) for Fly health checks
memory = "2048mb"512MB is too small; 2GB recommended
FASED_STATE_DIR = "/data"Persists state on the volume
FASED_STATE_DIR persists Fased config and credentials. Agent workspace files are controlled by agents.defaults.workspace or each Agent’s workspace setting, not by FASED_STATE_DIR. For a hosted volume, set the default Agent workspace to /data/workspace during setup or with:
fly ssh console --command "node dist/index.js config set agents.defaults.workspace /data/workspace"
Restart the gateway after changing config.

3) Set secrets

# Required: Gateway token (for non-loopback binding)
fly secrets set FASED_GATEWAY_TOKEN=$(openssl rand -hex 32)

# Optional model/channel secrets can be added later from the Control UI or as env vars.
# Example:
# fly secrets set OPENAI_API_KEY=sk-...
Notes:
  • Non-loopback binds (--bind lan) require FASED_GATEWAY_TOKEN for security.
  • Treat these tokens like passwords.
  • Prefer env vars over config file for all API keys and tokens. This keeps secrets out of fased.json where they could be accidentally exposed or logged.

4) Deploy

fly deploy -c deploy/hosting/fly.toml
First deploy builds the Docker image (~2-3 minutes). Subsequent deploys are faster. After deployment, verify:
fly status
fly logs
You should see:
[gateway] listening on ws://0.0.0.0:3000 (PID xxx)

5) Complete setup in the Control UI

Use a private local proxy instead of treating the public fly.dev URL as your normal operator entrypoint:
fly proxy 3000:3000 -a my-fased
Then open http://localhost:3000/ and paste your gateway token. If you open through fased dashboard or a tokenized dashboard link, Fased uses the link once, strips the token from the URL, and stores a Control UI session. Finish setup from the selected Agent:
  • Agent > Models for model auth and model roles
  • Chat for the first working message
  • Agent > Channels for Discord, Telegram, Slack, WhatsApp, and other routes
  • Agent > Services for web/search, GitHub, Gmail, and other API connectors
If you did not already set it, point the Agent workspace at the Fly volume before creating editable skills, files, or memory content:
fly ssh console --command "node dist/index.js config set agents.defaults.workspace /data/workspace"
If you need to edit raw config for debugging, with FASED_STATE_DIR=/data, the config path is /data/fased.json.

6) Access the Gateway

Use the local fly proxy URL for operator access whenever possible. Do not make the public Fly URL your normal admin surface unless you have separately reviewed the exposure.

Logs

fly logs              # Live logs
fly logs --no-tail    # Recent logs

SSH Console

fly ssh console

Troubleshooting

”App is not listening on expected address”

The gateway is binding to 127.0.0.1 instead of 0.0.0.0. Fix: Add --bind lan to your process command in deploy/hosting/fly.toml.

Health checks failing / connection refused

Fly can’t reach the gateway on the configured port. Fix: Ensure internal_port matches the gateway port (set --port 3000 or FASED_GATEWAY_PORT=3000).

OOM / Memory Issues

Container keeps restarting or getting killed. Signs: SIGABRT, v8::internal::Runtime_AllocateInYoungGeneration, or silent restarts. Fix: Increase memory in deploy/hosting/fly.toml:
[[vm]]
  memory = "2048mb"
Or update an existing machine:
fly machine update <machine-id> --vm-memory 2048 -y
Note: 512MB is too small. 1GB may work but can OOM under load or with verbose logging. 2GB is recommended.

Gateway Lock Issues

Gateway refuses to start with “already running” errors. This happens when the container restarts but the PID lock file persists on the volume. Fix: Delete the lock file:
fly ssh console --command "rm -f /data/gateway.*.lock"
fly machine restart <machine-id>
The lock file is at /data/gateway.*.lock (not in a subdirectory).

Config Not Being Read

If using --allow-unconfigured, the gateway creates a minimal config. Your custom config at /data/fased.json should be read on restart. Verify the config exists:
fly ssh console --command "cat /data/fased.json"

Writing Config via SSH

The fly ssh console -C command doesn’t support shell redirection. To write a config file:
# Use echo + tee (pipe from local to remote)
echo '{"your":"config"}' | fly ssh console -C "tee /data/fased.json"

# Or use sftp
fly sftp shell
> put /local/path/config.json /data/fased.json
Note: fly sftp may fail if the file already exists. Delete first:
fly ssh console --command "rm /data/fased.json"

State Not Persisting

If you lose credentials or sessions after a restart, the state dir is writing to the container filesystem. Fix: Ensure FASED_STATE_DIR=/data is set in deploy/hosting/fly.toml and redeploy.

Updates

# Pull latest changes
git pull

# Redeploy
fly deploy -c deploy/hosting/fly.toml

# Check health
fly status
fly logs

Updating Machine Command

If you need to change the startup command without a full redeploy:
# Get machine ID
fly machines list

# Update command
fly machine update <machine-id> --command "node dist/index.js gateway --port 3000 --bind lan" -y

# Or with memory increase
fly machine update <machine-id> --vm-memory 2048 --command "node dist/index.js gateway --port 3000 --bind lan" -y
Note: After fly deploy, the machine command may reset to what’s in deploy/hosting/fly.toml. If you made manual changes, re-apply them after deploy.

Private Deployment (Hardened)

By default, Fly allocates public IPs, making your gateway accessible at https://your-app.fly.dev. This is convenient but means your deployment is discoverable by internet scanners. For a hardened deployment with no public exposure, use the repo-backed private config, deploy/hosting/fly.private.toml.

When to use private deployment

  • You only make outbound calls/messages (no inbound webhooks)
  • You use a separate private access layer for operator control and do not rely on the public Fly URL for administration
  • You access the gateway via SSH, proxy, or WireGuard instead of browser
  • You want the deployment hidden from internet scanners

Setup

Use deploy/hosting/fly.private.toml instead of the standard config:
# Deploy with private config
fly deploy -c deploy/hosting/fly.private.toml
Or convert an existing deployment:
# List current IPs
fly ips list -a my-fased

# Release public IPs
fly ips release <public-ipv4> -a my-fased
fly ips release <public-ipv6> -a my-fased

# Switch to private config so future deploys don't re-allocate public IPs
# (remove [http_service] or deploy with fly.private.toml)
fly deploy -c deploy/hosting/fly.private.toml

# Allocate private-only IPv6
fly ips allocate-v6 --private -a my-fased
After this, fly ips list should show only a private type IP:
VERSION  IP                   TYPE             REGION
v6       fdaa:x:x:x:x::x      private          global

Accessing a private deployment

Since there’s no public URL, use one of these methods: Option 1: Local proxy (simplest)
# Forward local port 3000 to the app
fly proxy 3000:3000 -a my-fased

# Then open http://localhost:3000 in browser
Option 2: WireGuard VPN
# Create WireGuard config (one-time)
fly wireguard create

# Import to WireGuard client, then access via internal IPv6
# Example: http://[fdaa:x:x:x:x::x]:3000
Option 3: SSH only
fly ssh console -a my-fased

Webhooks with private deployment

If you need webhook callbacks (Twilio, Telnyx, etc.) without public exposure:
  1. Provider-specific tunnel or relay - for the webhook path only
  2. Outbound-only - Some providers work fine without inbound webhooks
Example voice-call config with a separate tunnel provider:
{
  "plugins": {
    "entries": {
      "voice-call": {
        "enabled": true,
        "config": {
          "provider": "twilio",
          "tunnel": { "provider": "custom" },
          "webhookSecurity": {
            "allowedHosts": ["example-tunnel-host"]
          }
        }
      }
    }
  }
}
Whatever relay or tunnel you use for inbound webhooks, keep it separate from the operator control path. Public webhook ingress is not the same thing as public admin access.

Notes

  • Fly.io uses x86 architecture (not ARM)
  • The Dockerfile is compatible with both architectures
  • For WhatsApp/Telegram onboarding, use fly ssh console
  • Persistent data lives on the volume at /data
  • Signal requires Java + signal-cli; use a custom image and keep memory at 2GB+.

Cost

With the recommended config (shared-cpu-2x, 2GB RAM):
  • ~$10-15/month depending on usage
  • Free tier includes some allowance
See Fly.io pricing for details.
