SSH Key Management

SSH keys provide secure access to your instances. Morph Cloud supports both user-level SSH keys (shared across instances) and instance-specific SSH keys for enhanced security.

Get Instance SSH Key

Retrieve the SSH key for a specific instance:

Python

from morphcloud.api import MorphCloudClient

client = MorphCloudClient()

instance_id = "morphvm_abc123"  # Replace with your instance ID

# Get instance and retrieve SSH key
instance = client.instances.get(instance_id)
ssh_key = instance.ssh_key()

print(f"Public Key:\n{ssh_key.public_key}")
print(f"Private Key:\n{ssh_key.private_key}")

TypeScript

import { MorphCloudClient } from 'morphcloud';

const client = new MorphCloudClient();

async function getInstanceSshKey() {
  const instance_id = "morphvm_abc123"; // Replace with your instance ID
  
  // Get instance and retrieve SSH key
  const instance = await client.instances.get({ instance_id: instance_id });
  const sshKey = await instance.ssh_key();
  
  console.log(`Public Key:\n${sshKey.publicKey}`);
  console.log(`Private Key:\n${sshKey.privateKey}`);
}

getInstanceSshKey();

CLI

# Get SSH key for an instance
morphcloud instance ssh-key get morphvm_abc123

Rotate Instance SSH Key

Generate a new SSH key pair for enhanced security:

Python

from morphcloud.api import MorphCloudClient

client = MorphCloudClient()

instance_id = "morphvm_abc123"  # Replace with your instance ID

# Get instance and rotate SSH key
instance = client.instances.get(instance_id)
new_ssh_key = instance.ssh_key_rotate()

print(f"New Public Key:\n{new_ssh_key.public_key}")
print(f"New Private Key:\n{new_ssh_key.private_key}")
print("SSH key rotated successfully!")

TypeScript

import { MorphCloudClient } from 'morphcloud';

const client = new MorphCloudClient();

async function rotateInstanceSshKey() {
  const instance_id = "morphvm_abc123"; // Replace with your instance ID
  
  // Get instance and rotate SSH key
  const instance = await client.instances.get({ instance_id: instance_id });
  const newSshKey = await instance.ssh_key_rotate();
  
  console.log(`New Public Key:\n${newSshKey.publicKey}`);
  console.log(`New Private Key:\n${newSshKey.privateKey}`);
  console.log("SSH key rotated successfully!");
}

rotateInstanceSshKey();

CLI

# Rotate SSH key for an instance
morphcloud instance ssh-key rotate morphvm_abc123

Best Practices

• Save private keys securely with appropriate file permissions (600)
• Rotate keys regularly for enhanced security
• Use instance-specific keys for production environments
• Keep private keys confidential and never share them

SSH key management ensures secure access to your Morph Cloud instances while maintaining flexibility and security.
