Step 1.5: Access the Instance

Once your instance is created, you will see it listed under Resources. Take note of the Public IP Address, which will be used to access and manage your instance.

To access your newly created instance, follow these steps:

1. Find your Instance’s Public IP: After creating your instance, note the public IP address associated with it, which is visible in the instance list.
2. Open SSH terminal: Use an SSH client like Terminal (for Linux/macOS) or PuTTY (for Windows).
3. Connect via SSH: Run the following command in your terminal:

   ssh root@<your-instance-ip>

Replace <your-instance-ip> with your instance’s actual public IP.

4. Enter your password: If prompted, input your instance’s root password. You should now be connected to your instance.
