  3. Connect to your VPN using your credentials

Connecting to Dragonfly Cloud​

Once your VPN connection is established:

  1. Use your standard Dragonfly client with the private endpoint address
  2. Your connection is now securely tunneled through the VPN
import dragonfly

# Connect to your private Dragonfly Cloud instance through VPN
client = dragonfly.connect(
    host='your-private-endpoint.internal',
    port=6379
)

# Now you can interact with your Dragonfly instance
client.set('key', 'value')
result = client.get('key')
print(result)  # Outputs: 'value'

Troubleshooting​

If you encounter connectivity issues:

  1. Verify your VPN connection is active
  2. Check that your VPN routes include the subnet of your Dragonfly instance
  3. Ensure your firewall rules allow traffic to the Dragonfly port
  4. Confirm your Dragonfly instance's network policy allows your VPN subnet
