morphcloud 0.1.61

A Python SDK and CLI tool for creating, managing, and interacting with Morph Cloud VMs.

Morph Cloud Python SDK

Overview

Morph Cloud is a powerful platform for creating, managing, and interacting with remote AI development environments called runtimes. It provides a comprehensive Python SDK and CLI to:

• Create and manage VM snapshots
• Start, stop, pause, and resume VM instances
• Execute commands via SSH
• Transfer files between local and remote environments
• Expose HTTP services with optional authentication
• Create Docker containers within instances
• Cache and reuse computational results with snapshot chains

Setup Guide

Prerequisites

• Python 3.11 or higher
• An account on MorphCloud

Getting Your API Key

1. Go to https://cloud.morph.so/web/api-keys
2. Log in with your credentials
3. Create a new API key

Documentation

Python API

Basic Usage

from morphcloud.api import MorphCloudClient

# Initialize the client
client = MorphCloudClient()

# List available base images
print("\n\nAvailable base images:")
images = client.images.list()
for image in images:
    print(f"  {image.id}:\t{image.name}")

# Create a snapshot from a base image
print("\nCreating snapshot from base image...", end="")
snapshot = client.snapshots.create(
    image_id="morphvm-minimal",
    vcpus=1,
    memory=512,
    disk_size=1024
)
print("done")

# Start an instance from the snapshot
print("Starting instance from snapshot.....", end="")
instance = client.instances.start(snapshot_id=snapshot.id)
print("done")


# Wait for the instance to be ready
print("Waiting until instance is ready.....", end="")
instance.wait_until_ready()
print("done")


# Stop the instance when done
print("Stopping the instance...............", end="")
instance.stop()
print("done\n")

Working with SSH

from morphcloud.api import MorphCloudClient

client = MorphCloudClient()
snapshot = client.snapshots.create(vcpus=1, memory=512, disk_size=1024, image_id="morphvm-minimal")

# Using context managers for automatic cleanup
with client.instances.start(snapshot_id=snapshot.id) as instance:
    instance.wait_until_ready()
    
    # Connect via SSH and run commands
    with instance.ssh() as ssh:
        # Run a basic command
        result = ssh.run("echo 'Hello from MorphCloud!'")
        print(result.stdout)
        
        # Install packages
        ssh.run("apt-get update && apt-get install -y python3-pip").raise_on_error()
        
        # Upload a local file to the instance
        ssh.copy_to("./local_script.py", "/home/user/remote_script.py")
        
        # Execute the uploaded script
        ssh.run("python3 /home/user/remote_script.py")
        
        # Download a file from the instance
        ssh.copy_from("/home/user/results.txt", "./local_results.txt")

HTTP Services and Port Forwarding

import time
import requests
from morphcloud.api import MorphCloudClient

client = MorphCloudClient()
snapshot = client.snapshots.get("your_snapshot_id")  # Use an existing snapshot

with client.instances.start(snapshot_id=snapshot.id) as instance:
    instance.wait_until_ready()
    
    with instance.ssh() as ssh:
        # Start a simple HTTP server on the instance
        ssh.run("python3 -m http.server 8080 &")
        
        # Method 1: Expose as HTTP service with public URL
        service_url = instance.expose_http_service("my-service", 8080)
        print(f"Service available at: {service_url}")
        
        # Method 2: Create an SSH tunnel for local port forwarding
        with ssh.tunnel(local_port=8888, remote_port=8080):
            time.sleep(1)  # Give the tunnel time to establish
            response = requests.get("http://localhost:8888")
            print(response.text)

Advanced: Snapshot Chains and Caching

One of Morph Cloud's powerful features is the ability to create chains of snapshots with cached operations:

from morphcloud.api import MorphCloudClient

client = MorphCloudClient()
base_snapshot = client.snapshots.get("your_base_snapshot_id")

# Each exec operation creates a new snapshot that includes the changes
# If you run the same command again, it will use the cached snapshot
python_snapshot = base_snapshot.exec("apt-get update && apt-get install -y python3 python3-pip")
numpy_snapshot = python_snapshot.exec("pip install numpy pandas matplotlib")

# Upload local files to a snapshot and create a new snapshot with those files
data_snapshot = numpy_snapshot.upload("./data/", "/home/user/data/", recursive=True)

# Run your analysis on the data
results_snapshot = data_snapshot.exec("python3 /home/user/data/analyze.py")

# Start an instance from the final snapshot with all changes applied
instance = client.instances.start(snapshot_id=results_snapshot.id)

Docker Container Integration

Set up instances that automatically redirect to Docker containers:

from morphcloud.api import MorphCloudClient

client = MorphCloudClient()
base_snapshot = client.snapshots.get("your_base_snapshot_id")

# Create a snapshot with a PostgreSQL container
postgres_snapshot = base_snapshot.as_container(
    image="postgres:13",
    container_name="postgres",
    env={"POSTGRES_PASSWORD": "example"},
    ports={5432: 5432}
)

# When you start an instance from this snapshot, all SSH sessions
# will automatically connect to the container instead of the host
with client.instances.start(snapshot_id=postgres_snapshot.id) as instance:
    instance.wait_until_ready()
    
    # This SSH session will connect directly to the container
    with instance.ssh() as ssh:
        ssh.run("psql -U postgres")

Asynchronous API

Morph Cloud also provides asynchronous versions of all methods:

import asyncio
from morphcloud.api import MorphCloudClient

async def main():
    client = MorphCloudClient()
    
    # Async list images
    images = await client.images.alist()
    
    # Async create snapshot
    snapshot = await client.snapshots.acreate(
        image_id="morphvm-minimal", 
        vcpus=1, 
        memory=512, 
        disk_size=1024
    )
    
    # Async start instance
    instance = await client.instances.astart(snapshot_id=snapshot.id)
    
    # Async wait for ready
    await instance.await_until_ready()
    
    # Async stop instance
    await instance.astop()

asyncio.run(main())
