Initial Deployment​

During the deployment process:

  • You will be logged out with the message:

Please wait until the installation is completed....
Connection to $IPADDRESS closed.

Wait at least 2 minutes before logging back in.

Accessing the Instance​

  1. Login to your instance:
ssh ubuntu@$IPADDRESS
  1. Switch to root:
sudo su -

Web Interface​

Configuration & Logs​

  • Modify configuration:
nano /etc/rethinkdb/instances.d/instance.conf
  • View logs:
ls /var/log/rethinkdb

User Management​

  • Default admin user: admin (no password set by default)
  • Update password with --initial-password at startup or via API
  • Web Admin UI connects as admin without password (not recommended for public interfaces)

Security Considerations​

  • Limit web UI exposure using --bind-http to restrict access
  • Prefer internal/private networks for cluster communication
  • Enable TLS and bind ports to specific IPs for external deployments
