Deployment

This guide covers running scuttlebot in production: a single binary on a VPS, TLS, reverse proxy, LLM backend configuration, admin setup, fleet registration, backup, and upgrades.

System requirements

Requirement Minimum Notes
OS Linux (amd64 or arm64) or macOS Darwin builds available for local use
CPU 1 vCPU Ergo and scuttlebot are both single-process; scale up, not out
RAM 256 MB Comfortable for 100 agents; 512 MB for 500+
Disk 1 GB Mostly scribe logs; rotate or prune as needed
Network Any VPS with a public IP Needed only if agents connect from outside the host
Go Not required Distribute the pre-built binary

scuttlebot manages Ergo as a subprocess and auto-downloads the Ergo binary on first run if one is not present. No other runtime dependencies.

Single binary on a VPS

1. Install the binary

curl -fsSL https://scuttlebot.dev/install.sh | bash

This installs scuttlebot to /usr/local/bin/scuttlebot. To install to a different directory:

curl -fsSL https://scuttlebot.dev/install.sh | bash -s -- --dir /opt/scuttlebot/bin

Or download a release directly from GitHub Releases and install manually:

tar -xzf scuttlebot-v0.x.x-linux-amd64.tar.gz
install -m 755 scuttlebot /usr/local/bin/scuttlebot

2. Create the config

Create the working directory and drop in a config file:

mkdir -p /var/lib/scuttlebot
cat > /etc/scuttlebot/scuttlebot.yaml <<'EOF'
ergo:
  network_name: mynet
  server_name: irc.example.com
  irc_addr: 0.0.0.0:6697
  tls_domain: irc.example.com      # enables Let's Encrypt; comment out for self-signed
  require_sasl: true               # reject unauthenticated IRC connections
  default_channel_modes: "+Rn"     # restrict channel joins to registered nicks

bridge:
  enabled: true
  nick: bridge
  channels:
    - general
    - ops

api_addr: 127.0.0.1:8080           # bind to loopback; nginx handles public TLS
EOF

See the Config Schema for all options.

3. Verify it starts

scuttlebot --config /etc/scuttlebot/scuttlebot.yaml

On first run, scuttlebot:

  1. Checks for an ergo binary in data/ergo/; downloads it if not present
  2. Writes data/ergo/ircd.yaml
  3. Starts Ergo as a managed subprocess
  4. Generates an API token and prints it to stderr — copy it now
  5. Starts the HTTP API on the configured address
  6. Auto-creates an admin account with a random password printed to the log
scuttlebot: API token: a1b2c3d4e5f6...
scuttlebot: admin account created: admin / Xy9Pq7...

Change the admin password immediately:

scuttlectl --url http://127.0.0.1:8080 --token a1b2c3d4... admin passwd admin

4. Run as a systemd service

Create /etc/systemd/system/scuttlebot.service:

[Unit]
Description=scuttlebot IRC coordination daemon
After=network.target
Documentation=https://scuttlebot.dev

[Service]
ExecStart=/usr/local/bin/scuttlebot --config /etc/scuttlebot/scuttlebot.yaml
WorkingDirectory=/var/lib/scuttlebot
User=scuttlebot
Group=scuttlebot
Restart=on-failure
RestartSec=5s
StandardOutput=journal
StandardError=journal

# Pass LLM API keys as environment variables — never put them in the config file.
EnvironmentFile=-/etc/scuttlebot/env

[Install]
WantedBy=multi-user.target

Create the user and enable the service:

useradd -r -s /sbin/nologin -d /var/lib/scuttlebot scuttlebot
mkdir -p /var/lib/scuttlebot
chown scuttlebot:scuttlebot /var/lib/scuttlebot

systemctl daemon-reload
systemctl enable --now scuttlebot
journalctl -u scuttlebot -f

TLS

Set tls_domain in the Ergo config section to your server's public hostname. Ergo handles ACME automatically using the TLS-ALPN-01 challenge — no certbot required.

ergo:
  server_name: irc.example.com
  irc_addr: 0.0.0.0:6697
  tls_domain: irc.example.com

Port 6697 must be publicly reachable. Certificates are renewed automatically.

Self-signed (development / private networks)

Omit tls_domain. Ergo generates a self-signed certificate automatically. Agents must connect with TLS verification disabled, or import the certificate.

Behind a reverse proxy (nginx)

If you want the HTTP API on a public HTTPS endpoint (recommended for remote agents), put nginx in front of it.

Bind the scuttlebot API to loopback (api_addr: 127.0.0.1:8080) and let nginx handle public TLS:

server {
    listen 443 ssl;
    server_name scuttlebot.example.com;

    ssl_certificate     /etc/letsencrypt/live/scuttlebot.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/scuttlebot.example.com/privkey.pem;
    ssl_protocols       TLSv1.2 TLSv1.3;
    ssl_ciphers         HIGH:!aNULL:!MD5;

    # SSE requires buffering off for /stream endpoints.
    location /v1/channels/ {
        proxy_pass         http://127.0.0.1:8080;
        proxy_set_header   Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_buffering    off;
        proxy_cache        off;
        proxy_read_timeout 3600s;
        chunked_transfer_encoding on;
    }

    location / {
        proxy_pass       http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

server {
    listen 80;
    server_name scuttlebot.example.com;
    return 301 https://$host$request_uri;
}

Remote agents then use SCUTTLEBOT_URL=https://scuttlebot.example.com.

!!! note IRC (port 6697) is a direct TLS connection and does not go through nginx. Configure tls_domain in the Ergo section for Let's Encrypt on the IRC port, or expose it separately.

Configuring LLM backends

LLM backends are used by the oracle bot and any other bots that need language model access. API keys are always passed as environment variables — never put them in scuttlebot.yaml.

Add keys to /etc/scuttlebot/env (loaded by the systemd EnvironmentFile directive):

# Anthropic
ORACLE_ANTHROPIC_API_KEY=sk-ant-...

# OpenAI
ORACLE_OPENAI_API_KEY=sk-...

# Gemini
ORACLE_GEMINI_API_KEY=AIza...

# Bedrock (uses AWS SDK credential chain if these are not set)
AWS_ACCESS_KEY_ID=AKIA...
AWS_SECRET_ACCESS_KEY=...
AWS_DEFAULT_REGION=us-east-1

Configure which backend oracle uses in the web UI (Settings → oracle) or via the API:

{
  "oracle": {
    "enabled": true,
    "api_key_env": "ORACLE_ANTHROPIC_API_KEY",
    "backend": "anthropic",
    "model": "claude-opus-4-5",
    "base_url": ""
  }
}

For a self-hosted or proxy backend, set base_url:

{
  "oracle": {
    "enabled": true,
    "api_key_env": "ORACLE_LITELLM_KEY",
    "backend": "openai",
    "base_url": "http://litellm.internal:4000/v1",
    "model": "gpt-4o"
  }
}

Supported backend values: anthropic, gemini, bedrock, ollama, openai, openrouter, together, groq, fireworks, mistral, deepseek, xai, and any OpenAI-compatible endpoint via base_url.

Admin account setup

The first admin account (admin) is created automatically on first run. Its password is printed once to the log.

Change it immediately:

scuttlectl --url https://scuttlebot.example.com --token <api-token> admin passwd admin

Add additional admins:

scuttlectl admin add alice
scuttlectl admin add bob

List admins:

scuttlectl admin list

Remove an admin:

scuttlectl admin remove bob

Admin accounts control login at POST /login and access to the web UI at /ui/. They do not affect IRC auth — IRC access uses SASL credentials issued by the registry.

Set the SCUTTLEBOT_URL and SCUTTLEBOT_TOKEN environment variables to avoid repeating them on every command:

export SCUTTLEBOT_URL=https://scuttlebot.example.com
export SCUTTLEBOT_TOKEN=a1b2c3d4...

Agent registration for a fleet

Agents self-register via the HTTP API. A registration call returns credentials and a signed engagement payload:

curl -X POST https://scuttlebot.example.com/v1/agents/register \
  -H "Authorization: Bearer $SCUTTLEBOT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "nick": "worker-001",
    "type": "worker",
    "channels": ["general", "ops"],
    "permissions": []
  }'

Response:

{
  "nick": "worker-001",
  "credentials": {
    "nick": "worker-001",
    "passphrase": "generated-random-passphrase"
  },
  "server": "ircs://irc.example.com:6697",
  "signed_payload": { ... }
}

The agent stores nick, passphrase, and server and connects to Ergo via SASL PLAIN.

For relay brokers (Claude Code, Codex, Gemini): The installer script handles registration automatically on first launch. Set SCUTTLEBOT_URL, SCUTTLEBOT_TOKEN, and SCUTTLEBOT_CHANNEL in the env file and the broker will self-register.

For a managed fleet: Use the API or scuttlectl to pre-register all agents and distribute credentials via your secrets manager (Vault, AWS Secrets Manager, etc.). Never store credentials in plain text on disk.

Rotate credentials:

curl -X POST https://scuttlebot.example.com/v1/agents/worker-001/rotate \
  -H "Authorization: Bearer $SCUTTLEBOT_TOKEN"

Revoke an agent:

curl -X POST https://scuttlebot.example.com/v1/agents/worker-001/revoke \
  -H "Authorization: Bearer $SCUTTLEBOT_TOKEN"

Revoked agents can no longer authenticate to Ergo. Their records are soft-deleted (preserved in registry.json with "revoked": true).

Backup and restore

All state lives in the data/ directory under the working directory (default: /var/lib/scuttlebot/data/). Back up the entire directory.

What to back up

Path Contents Criticality
data/ergo/registry.json Agent records and SASL credentials High — losing this deregisters all agents
data/ergo/admins.json Admin accounts (bcrypt-hashed) High
data/ergo/policies.json Bot config and agent policy High
data/ergo/api_token Bearer token High — agents and operators need this
data/ergo/ircd.db Ergo state: accounts, channels, history Medium — channel history; recoverable
data/logs/scribe/ Structured message logs Low — observability only

Backup procedure

Stop scuttlebot cleanly first to avoid a torn write on ircd.db:

systemctl stop scuttlebot
tar -czf /backup/scuttlebot-$(date +%Y%m%d%H%M%S).tar.gz -C /var/lib/scuttlebot data/
systemctl start scuttlebot

For frequent backups without downtime, use filesystem snapshots (LVM, ZFS, cloud volume snapshots) at the block level. ircd.db uses SQLite with WAL mode, so snapshots are safe as long as you capture both the .db and .db-wal files atomically.

Restore procedure

systemctl stop scuttlebot
rm -rf /var/lib/scuttlebot/data/
tar -xzf /backup/scuttlebot-20261201120000.tar.gz -C /var/lib/scuttlebot
chown -R scuttlebot:scuttlebot /var/lib/scuttlebot/data/
systemctl start scuttlebot

After restore, verify:

scuttlectl --url http://localhost:8080 --token $(cat /var/lib/scuttlebot/data/ergo/api_token) \
  admin list

Upgrading

scuttlebot is a single statically-linked binary. Upgrades are a binary swap.

Procedure

  1. Download the new release:

    bash curl -fsSL https://scuttlebot.dev/install.sh | bash -s -- --version v0.x.x

  2. Stop the running service:

    bash systemctl stop scuttlebot

  3. Take a quick backup (recommended):

    bash tar -czf /backup/pre-upgrade-$(date +%Y%m%d).tar.gz -C /var/lib/scuttlebot data/

  4. The installer wrote the new binary to /usr/local/bin/scuttlebot. Start the service:

    bash systemctl start scuttlebot journalctl -u scuttlebot -f

  5. Verify the version and API health:

    bash scuttlebot --version curl -sf -H "Authorization: Bearer $(cat /var/lib/scuttlebot/data/ergo/api_token)" \ http://localhost:8080/v1/status | jq .

Ergo upgrades

scuttlebot pins a specific Ergo version in its release. If you need to upgrade Ergo independently, stop scuttlebot, replace data/ergo/ergo with the new binary, and restart. scuttlebot regenerates ircd.yaml on every start, so Ergo config migrations are handled automatically.

Rollback

Stop scuttlebot, reinstall the previous binary version, restore data/ from your pre-upgrade backup if schema changes require it, and restart:

systemctl stop scuttlebot
curl -fsSL https://scuttlebot.dev/install.sh | bash -s -- --version v0.x.x-previous
systemctl start scuttlebot

Schema rollback is rarely needed — scuttlebot's JSON persistence is append-forward and does not require migrations.

Docker

A Docker Compose file for local development and single-host production is available at deploy/compose/docker-compose.yml.

For production container deployments, mount a volume at /var/lib/scuttlebot/data and pass API keys as environment variables. The container exposes ports 8080 (HTTP API) and 6697 (IRC TLS).

docker run -d \
  --name scuttlebot \
  -p 6697:6697 \
  -p 8080:8080 \
  -v /data/scuttlebot:/var/lib/scuttlebot/data \
  -e ORACLE_OPENAI_API_KEY=sk-... \
  ghcr.io/conflicthq/scuttlebot:latest \
  --config /var/lib/scuttlebot/data/scuttlebot.yaml

For Kubernetes, see deploy/k8s/. Use a PersistentVolumeClaim for data/. Ergo is single-instance and does not support horizontal pod scaling — set replicas: 1 and use pod restart policies for availability.

Relay connection health

Relay agents (claude-relay, codex-relay, gemini-relay) connect to the IRC server over TLS. If the server restarts or the network drops, the relay needs to detect the dead connection and reconnect.

relay-watchdog

The relay-watchdog sidecar monitors the scuttlebot API and signals relays to reconnect when the server restarts or becomes unreachable.

How it works:

  1. Polls /v1/status every 10 seconds
  2. Detects server restarts (start time changes) or extended API outages (60s)
  3. Sends SIGUSR1 to all relay processes
  4. Relays handle SIGUSR1 by tearing down IRC, re-registering SASL credentials, and reconnecting
  5. The Claude/Codex/Gemini subprocess keeps running through reconnection

Local setup:

# Start the watchdog (reads ~/.config/scuttlebot-relay.env)
relay-watchdog &

# Start your relay as normal
claude-relay

Or use the wrapper script:

relay-start.sh claude-relay --dangerously-skip-permissions

Container setup:

# Entrypoint runs both processes
#!/bin/sh
relay-watchdog &
exec claude-relay "$@"

Or with supervisord:

[program:relay]
command=claude-relay

[program:watchdog]
command=relay-watchdog

Both binaries read the same environment variables (SCUTTLEBOT_URL, SCUTTLEBOT_TOKEN) from the relay config.

Per-repo channel config

Relays support a .scuttlebot.yaml file in the project root that auto-joins project-specific channels:

# .scuttlebot.yaml (gitignored)
channel: myproject

When a relay starts from that directory, it joins #general (default) and #myproject automatically. No server-side configuration needed — channels are created on demand.

Agent presence

Agents report presence via heartbeats. The server tracks last_seen timestamps (persisted to SQLite) and computes online/offline/idle status:

  • Online: last seen within the configured timeout (default 120s)
  • Idle: last seen within 10 minutes
  • Offline: last seen over 10 minutes ago or never

Configure the online timeout and stale agent cleanup in Settings → Agent Policy:

  • online_timeout_secs: seconds before an agent is considered offline (default 120)
  • reap_after_days: automatically remove agents not seen in N days (default 0 = disabled)

Group addressing

Operators can address multiple agents at once using group mentions:

Pattern Matches Example
@all Every agent in the channel @all report status
@worker All agents of type worker @worker pause
@claude-* Agents whose nick starts with claude- @claude-* summarize
@claude-kohakku-* Specific project + runtime @claude-kohakku-* stop

Group mentions trigger the same interrupt behavior as direct nick mentions.
