How do I deploy a Lambda function using the AWS SDK?

To deploy a Lambda function using the AWS SDK, you can use the AWS SDK for JavaScript. First, ensure you have the SDK installed and configured.

What are the steps to configure the AWS SDK?

You need to set up your AWS credentials and region. You can do this by creating a configuration file or using environment variables.

Can you show me a sample code for deploying a Lambda function?

Sure! Here's a simple example:

const AWS = require('aws-sdk');
const lambda = new AWS.Lambda();

const params = {
  FunctionName: 'myFunction',
  Code: { /* your code here */ },
  Handler: 'index.handler',
  Role: 'arn:aws:iam::account-id:role/execution_role',
  Runtime: 'nodejs14.x',
};

lambda.createFunction(params, (err, data) => {
  if (err) console.log(err);
  else console.log(data);
});

What permissions do I need for the Lambda execution role?

The execution role should have permissions like AWSLambdaBasicExecutionRole for logging and any other permissions your function needs to access AWS resources.
