1. Vultr Compute Instances for Deep Learning Workloads


    Provisioning compute instances on Vultr for deep learning workloads typically involves selecting instances with adequate CPU/GPU resources and memory. Pulumi allows you to define these resources as code, enabling you to create, update, and manage your infrastructure in a repeatable and predictable manner. The following Pulumi program in Python will guide you through setting up compute instances on Vultr, configured for deep learning tasks.

    Explanation of Resources

    We'll use a few resources from the Vultr Pulumi provider to accomplish this:

    • vultr.Instance: Represents a compute instance in Vultr. You can specify the operating system, the plan (which determines the vCPU, RAM, and disk sizes), and the region where the instance will be deployed. For deep learning workloads, we'll choose a plan that offers GPU capabilities.
    • vultr.Vpc: Represents a Virtual Private Cloud (VPC) on Vultr, providing an isolated network environment for your resources.
    • vultr.SshKey: Allows you to manage SSH keys that can be assigned to your compute instance for secure access.

    We'll create a VPC to host the instance(s), deploy a compute instance with a GPU-oriented plan, and add an SSH key for secure connection to the instance.

    Defining The Infrastructure

    Below is a Pulumi program in Python that defines this infrastructure:

    import pulumi import pulumi_vultr as vultr # Configure your Vultr provider settings (such as API key) via environment variables or the Pulumi configuration system. # Create a VPC on Vultr to isolate our compute resources. # You may need to define CIDR and other properties depending on your network requirements. vpc = vultr.Vpc("deep-learning-vpc", region="ewr", # Choose the region closest to your location or your data sources v4_subnet="", v4_subnet_mask=24, description="VPC for deep learning instances" ) # Provision a GPU-based compute instance on Vultr. # You will need to select an appropriate plan and operating system that supports your deep learning framework. instance = vultr.Instance("gpu-instance", plan="vc2-4c-8gb", # Replace with a GPU-based plan suitable for deep learning. region=vpc.region, os_id=387, # This is an example OS ID; replace with the ID of the OS you wish to use. label="deep-learning-instance", vpc_ids=[vpc.id], enable_ipv6=True, tag=["deep-learning"] # Use tags for organizing and filtering resources. ) # Add an SSH key to your Vultr account and associate it with the compute instance for secure access. ssh_key = vultr.SshKey("my-ssh-key", ssh_key="ssh-rsa AAAAB3N...", # Replace with your public SSH key. label="deep-learning-key" ) # Update our instance to use the SSH key we just added. # This is done by referencing the `ssh_key_ids` attribute of our instance resource. pulumi.Output.all(instance.id, ssh_key.id).apply(lambda ids: vultr.Instance("gpu-instance-with-ssh", instance_id=ids[0], ssh_key_ids=[ids[1]] )) # Output the IP address of the instance so you can connect to it. pulumi.export("instance_ip", instance.ipv4_address) # Output the ID of the instance for future reference or to use in other automation. pulumi.export("instance_id", instance.id)

    Running the Pulumi Program

    To run the program:

    1. Ensure you have Pulumi and Python installed.
    2. Set up your Vultr API access by exporting your Vultr API key as an environment variable (VULTR_API_KEY).
    3. Save the above code to a file named __main__.py.
    4. Run pulumi up in the same directory as your file to create the resources.
    5. The output will display the IP address and ID of the instance.

    Connecting to the Instance

    Once the instance is running, you can connect to it via SSH using the IP address output by Pulumi and the private key corresponding to the SSH public key you provided:

    ssh -i /path/to/private-key root@<instance-ip>

    Replace /path/to/private-key with the path to your private SSH key and <instance-ip> with the IP address output by Pulumi.


    By using Pulumi, you have a repeatable and version-controlled method of provisioning and managing your deep learning infrastructure on Vultr. You can easily scale your resources, update configurations, or replicate environments as needed.
