OmniRoute Fly.io Deployment Guide

This document describes the actual deployment process for OmniRoute on Fly.io, covering two scenarios:

• Deploying the current project to Fly.io for the first time
• Publishing subsequent code updates
• New projects following the same deployment workflow

This guide is based on a verified working configuration for the current project. The application name is omniroute.

---

1. Deployment Goals

• Platform: Fly.io
• Deployment method: Local flyctl direct publish
• Runtime: Using the existing Dockerfile and fly.toml in the repository
• Data persistence: Fly Volume mounted to /data
• Access URL: https://omniroute.fly.dev/

---

2. Current Project Key Configuration

The fly.toml in the current repository has been confirmed to contain the following key items:

app = 'omniroute'
primary_region = 'sin'

[[mounts]]
  source = 'data'
  destination = '/data'

[processes]
  app = 'node run-standalone.mjs'

[http_service]
  internal_port = 20128

[env]
  TZ = "Asia/Shanghai"
  HOST = "0.0.0.0"
  HOSTNAME = "0.0.0.0"
  BIND = "0.0.0.0"

Notes:

• app = 'omniroute' determines which Fly application the deployment targets
• destination = '/data' determines the persistent volume mount directory
• This project must set DATA_DIR=/data, otherwise the database and keys will be written to the container's temporary directory

---

3. Prerequisites

3.1 Installing the Fly CLI

Windows PowerShell:

pwsh -Command "iwr https://fly.io/install.ps1 -useb | iex"

If the install script fails in your environment, you can also manually download the flyctl binary and add it to your PATH.

3.2 Logging in to Your Fly Account

flyctl auth login

3.3 Verifying Login Status

flyctl auth whoami
flyctl version

---

4. First-Time Deployment of the Current Project

4.1 Clone the Code and Enter the Directory

git clone https://github.com/diegosouzapw/OmniRoute.git
cd OmniRoute

4.2 Confirm the Application Name

Open fly.toml and verify the following line:

app = 'omniroute'

If you are deploying to your own new application, you can change it to a globally unique name, for example:

app = 'omniroute-yourname'

Note:

• Make sure the application you see in the console matches the app value in fly.toml
• If you previously used a different name, such as oroute, do not confuse it with omniroute

4.3 Create the Application

If the application does not yet exist:

flyctl apps create omniroute

If you changed the application name, replace omniroute with your chosen name.

4.4 First Deploy

flyctl deploy

---

5. Required Parameters

This project recommends configuring at least the following parameters on Fly.io.

5.1 Verified Parameters

These parameters have been used in actual deployments on the current omniroute application:

• API_KEY_SECRET
• DATA_DIR
• JWT_SECRET
• MACHINE_ID_SALT
• NEXT_PUBLIC_BASE_URL
• OMNIROUTE_WS_BRIDGE_SECRET (required in production — used for WebSocket bridge authentication)
• STORAGE_ENCRYPTION_KEY

5.2 About INITIAL_PASSWORD

The current project does not set INITIAL_PASSWORD because this deployment does not require it.

If it is not set:

• The startup log will indicate the default password is CHANGEME
• You should change the login password in system settings as soon as possible after deployment

If you want to initialize the backend password unattended, you can add it later:

• INITIAL_PASSWORD

---

6. Recommended Parameters

6.1 Secrets Configuration

The following variables are recommended for Fly Secrets:

Variable	Recommendation	Description
API_KEY_SECRET	Required	Used for API Key generation and validation
JWT_SECRET	Required	Used for login sessions and JWT signing
OMNIROUTE_WS_BRIDGE_SECRET	Required in production	WebSocket bridge authentication secret
STORAGE_ENCRYPTION_KEY	Strongly recommended	Encrypts sensitive connection information at rest
MACHINE_ID_SALT	Recommended	Generates a stable machine identifier
INITIAL_PASSWORD	Optional	Sets the initial backend password at first deployment
OAuth/API private credentials	As needed	External platform authentication configuration

6.2 Recommended Values for the Current Project

Variable	Recommended Value
DATA_DIR	/data
NEXT_PUBLIC_BASE_URL	https://omniroute.fly.dev

Notes:

• DATA_DIR=/data is critical and must match the Fly Volume mount point
• NEXT_PUBLIC_BASE_URL is used by the scheduler, frontend callbacks, and similar scenarios

6.3 OAuth Callback URL Configuration

If you need to enable OAuth-based providers (e.g. Antigravity, Gemini, Cursor) on the Fly.io deployment, make sure of the following two points:

1. Set NEXT_PUBLIC_BASE_URL to your public HTTPS domain

   flyctl secrets set NEXT_PUBLIC_BASE_URL=https://omniroute.fly.dev -a omniroute

   If you are using a custom domain, replace it with the corresponding domain (e.g. https://omniroute.yourdomain.com).

2. Configure the callback URL on the provider console

   All OAuth providers share the single callback path /callback — there is NO per-provider callback route:

   <NEXT_PUBLIC_BASE_URL>/callback
   

   For example, regardless of Gemini, Antigravity, Cursor, or GitLab Duo:

   • https://omniroute.fly.dev/callback

   If NEXT_PUBLIC_BASE_URL does not match the callback URL registered with the provider, the OAuth flow will fail at the browser redirect step.

---

7. One-Command Secret Setup

The following commands generate secure random values and write all required parameters for the current project to Fly Secrets in one step.

Notes:

• Does not include INITIAL_PASSWORD
• Intended for the current project omniroute

$apiKeySecret = [Convert]::ToHexString((1..32 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 })).ToLower()
$jwtSecret = [Convert]::ToHexString((1..64 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 })).ToLower()
$machineIdSalt = [Convert]::ToHexString((1..32 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 })).ToLower()
$storageKey = [Convert]::ToHexString((1..32 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 })).ToLower()
$wsBridgeSecret = [Convert]::ToHexString((1..32 | ForEach-Object { Get-Random -Minimum 0 -Maximum 256 })).ToLower()

flyctl secrets set `
  API_KEY_SECRET=$apiKeySecret `
  JWT_SECRET=$jwtSecret `
  MACHINE_ID_SALT=$machineIdSalt `
  STORAGE_ENCRYPTION_KEY=$storageKey `
  OMNIROUTE_WS_BRIDGE_SECRET=$wsBridgeSecret `
  DATA_DIR=/data `
  NEXT_PUBLIC_BASE_URL=https://omniroute.fly.dev `
  -a omniroute

On Linux / macOS, you can also use openssl rand -hex 32:

flyctl secrets set OMNIROUTE_WS_BRIDGE_SECRET=$(openssl rand -hex 32) -a omniroute

Notes:

• OMNIROUTE_WS_BRIDGE_SECRET is required in production; missing it will break the WebSocket bridge handshake

If you also want to set an initial password:

flyctl secrets set INITIAL_PASSWORD=your-strong-password -a omniroute

---

8. Viewing Current Parameters

flyctl secrets list -a omniroute

If the Secrets page in the console does not show the expected variables, check:

• That you are viewing the omniroute application
• That the app value in fly.toml matches the application in the console

---

9. Subsequent Updates and Releases

After code updates, the release process is straightforward:

git pull
flyctl deploy

If you only need to update parameters without changing code:

flyctl secrets set KEY=value -a omniroute

Fly will automatically perform a rolling update of machines.

9.1 Tracking Upstream Repository Updates While Preserving Your Fork's fly.toml

If the current repository is a fork and you want to sync updates from the upstream https://github.com/diegosouzapw/OmniRoute, follow the workflow below.

First, verify your remotes:

git remote -v

You should see at least:

• origin pointing to your own fork
• upstream pointing to the original repository

If upstream is not configured, add it:

git remote add upstream https://github.com/diegosouzapw/OmniRoute.git

Before syncing with upstream, fetch the latest commits and tags:

git fetch upstream --tags

Check the current version and upstream tags:

git describe --tags --always
git show --no-patch --oneline v3.4.7

Note: The current project version is v3.8.0. The v3.4.7 references below are kept as historical examples only. For actual releases, use :latest or the current version tag (e.g. :v3.8.0).

If you want to merge the latest upstream main while forcefully keeping your fork's fly.toml, follow this workflow:

git merge upstream/main
git checkout HEAD~1 -- fly.toml
git add -- fly.toml
git commit -m "chore(deploy): keep fork fly.toml"
git push origin main

Notes:

• git merge upstream/main syncs the latest code from the original repository
• git checkout HEAD~1 -- fly.toml restores your fork's own fly.toml from before the merge
• If upstream did not modify fly.toml, this step will not introduce any differences
• If upstream did modify fly.toml, this step ensures your Fly application name, volume mount, region, and other fork-specific deployment configuration are not overwritten

If you want to align with a specific release tag (e.g. v3.4.7), first verify that the tag is already included in upstream/main:

git merge-base --is-ancestor v3.4.7 upstream/main

A successful return means upstream/main already contains that version; you can simply merge upstream/main.

9.2 Standard Release Sequence After Syncing Upstream

After syncing with the original repository, follow this recommended release order:

1. git fetch upstream --tags
2. git merge upstream/main
3. Restore the fork's fly.toml
4. git push origin main
5. flyctl deploy
6. flyctl status -a omniroute
7. flyctl logs --no-tail -a omniroute

This is the actual workflow used when upgrading the current project to v3.4.7 (the example refers to a historical version; the current actual version is v3.8.0).

10. Post-Deployment Checks

10.1 Check Application Status

flyctl status -a omniroute

10.2 View Startup Logs

flyctl logs --no-tail -a omniroute

10.3 Verify Site Accessibility

try {
  (Invoke-WebRequest -Uri "https://omniroute.fly.dev" -MaximumRedirection 5 -UseBasicParsing).StatusCode
} catch {
  if ($_.Exception.Response) {
    $_.Exception.Response.StatusCode.value__
  } else {
    throw
  }
}

A return value of 200 indicates the site is responding normally.

---

11. Success Indicators

After a successful deployment, the logs should show content similar to:

[bootstrap] Secrets persisted to: /data/server.env
[DB] SQLite database ready: /data/storage.sqlite

These two points are critical:

• /data/server.env confirms the runtime secrets are written to the persistent volume
• /data/storage.sqlite confirms the database is written to the persistent volume

If you see /app/data/... instead, DATA_DIR is misconfigured and must be corrected immediately.

---

12. Common Issues

12.1 Secrets Page Is Empty

There are usually two reasons:

• You have not yet run flyctl secrets set
• You are viewing a different application (e.g. oroute instead of omniroute)

12.2 flyctl deploy Reports app not found

Create the application first:

flyctl apps create omniroute

12.3 fly.toml Parsing Fails

Check the following:

• Whether there are garbled characters in comments
• Whether TOML quoting and indentation are correct

12.4 Data Is Not Persisting

Verify both of the following:

• fly.toml contains destination = '/data'
• DATA_DIR is set to /data

12.5 Can It Run Without INITIAL_PASSWORD?

Yes, it can run. It will fall back to the default CHANGEME password. It is recommended to change the backend password as soon as possible in production.

---

13. Reusing for New Projects

If you are deploying a new project following this document, you only need to change these items:

1. Change the app value in fly.toml
2. Change NEXT_PUBLIC_BASE_URL
3. Keep DATA_DIR=/data
4. Regenerate API_KEY_SECRET, JWT_SECRET, MACHINE_ID_SALT, and STORAGE_ENCRYPTION_KEY
5. After the first deployment, verify that logs are written to /data

Do not reuse keys from a previous project.

---

14. Minimal Release Checklist for the Current Project

The most commonly used commands for subsequent releases are:

flyctl auth whoami
flyctl status -a omniroute
flyctl secrets list -a omniroute
flyctl deploy
flyctl logs --no-tail -a omniroute

For a normal release, the core command is simply:

flyctl deploy

For a first-time deployment in a new environment, the core steps are:

1. flyctl auth login
2. flyctl apps create omniroute
3. flyctl secrets set ... -a omniroute
4. flyctl deploy
5. flyctl logs --no-tail -a omniroute
