A .NET library for interacting with theLambda API.

Installation

Install the library viaNuGet:

dotnet add package lambda-dotnet

Extensions

Install optional library extensions for more functionality, depending on your use case.

Dependency Injection

Integrate lambda-dotnet and your DI container of choice. Install the extension library viaNuGet:

dotnet add package lambda-dotnet-dependencyinjection

Usage

  1. Obtain an API key from theLambda Cloud Dashboard (requires a Lambda account).
  2. Pass the API key into a new instance of theLambdaCloudService class or use a configuredHttpClient if advanced configuration (e.g., proxies) is required.
  3. Use the methods available onLambdaCloudService to interact with the Lambda Cloud API.

Initialization

The library can be initialized in three ways:

Basic Initialization

Pass in your API key directly:

varlambdaCloud=newLambdaCloudService("YOUR_LAMBDA_API_KEY");

Advanced Initialization

Use an existingHttpClient, ensuring thatBaseAddress and anAuthorization header have been set:

varhttpClient=newHttpClient{BaseAddress=newUri("https://cloud.lambdalabs.com/api/v1/"),Timeout=TimeSpan.FromSeconds(5)};httpClient.DefaultRequestHeaders.Authorization=newAuthenticationHeaderValue("Bearer","YOUR_LAMBDA_API_KEY");varlambdaCloud=newLambdaCloudService(httpClient);

Dependency Injection

If you've installed the appropriate extension library.

  1. RegisterLambdaCloudService with your dependency container:
services.AddLambdaCloudHttpClient(options=>{options.BaseUrl=newUri("https://cloud.lambdalabs.com/api/v1/");options.ApiKey="YOUR_LAMBDA_API_KEY";});
  1. InjectILambdaCloudService where needed:
publicclassMyClass{privatereadonlyILambdaCloudServicelambdaCloud;publicMyClass(ILambdaCloudServicelambdaCloud){this.lambdaCloud=lambdaCloud;}}

List Instances

To list your running instances:

varinstances=awaitlambdaCloud.Instances.GetAllAsync();

To retrieve the details of an instance:

varinstanceId= ...var instance=awaitlambdaCloud.Instances.GetAsync(instanceId);

List Instance Types

To list the instance types offered by Lambda Cloud and explore their specs as well as their region-specific availability:

varinstanceTypeAvailabilities=lambdaCloud.Instances.GetAllTypeAvailabilityAsync();varinstanceTypesToLaunch=instanceTypeAvailabilities.Where(x=>x.Type.Specifications.GpuCount>=4).Where(x=>x.RegionsWithCapacity.Any()).Select(x=>x.Type)

Launching Instances

You can launch an instance in the following way:

varoptions=newLambdaCloudInstanceLaunchOptions(){RegionName="us-east-1",TypeName="gpu_1x_a100_sxm4",KeyNames=["my-ssh-key"],Quantity=1}varinstance=awaitlambdaCloud.Instances.LaunchAsync(options);

Restarting or Terminating Instances

To restart one or more running instances:

varinstances= ...var options=newLambdaCloudInstanceRestartOptions(){Ids=[instances[0].Id,instances[1].Id, ...]}var restartedInstances=awaitlambdaCloud.RestartAsync(options);

To terminate one or more running instances:

varinstances= ...var options=newLambdaCloudInstanceTerminateOptions(){Ids=[instances[0].Id,instances[1].Id, ...]}var terminatedInstances=awaitlambdaCloud.TerminateAsync(options);

List SSH Keys

To list the SSH keys saved in your account:

varkeys=awaitlambdaCloud.Keys.GetAllAsync();

Adding or Generating a SSH Key

To add an existing SSH key to your account:

varoptions=newLambdaCloudKeyAddOrGenerateOptions(){Name="my-existing-key",PublicKey="<YOUR_PUBLIC_KEY_HERE>"}varkey=awaitlambdaCloud.Keys.AddOrGenerateAsync(options);

To generate a new SSH key pair:

varoptions=newLambdaCloudKeyAddOrGenerateOptions(){Name="my-generated-key",PublicKey=null// Omit the public key}varkey=awaitlambdaCloud.Keys.AddOrGenerateAsync(options);// Make sure to save the private key returned to you.awaitFile.WriteAllTextAsync("my-generated-key.pem",key.PrivateKey);

Deleting an SSH Key

To delete an SSH key from your account:

varkey= ...awaitlambdaCloud.Keys.DeleteAsync(key.Id);

Listing Filesystems

To list your persistent storage filesystems:

varfilesystems=awaitlambdaCloud.Filesystems.GetAllAsync();

Documentation

Refer to theUsage section above for a quick start, or consult the inline documentation while working in your IDE.For detailed information about the underlying API endpoints, parameters, and expected responses, refer to Lambda'sCloud API documentation as well as theirCloud API reference.
