If you’re looking to automate the process of deploying your AWS Lambda functions, you’ve come to the right place. In this blog post, we’ll show you how to use the AWS Command Line Interface (CLI) to deploy your Lambda functions.
First, let’s take a look at the Lambda function we’ll be deploying. We’ll be using the following Node.js code, which prints “Hello, world!” to the console:
Next, we need to package our Lambda function code and dependencies into a zip file. We can do this using the AWS CLI with the following command:
aws lambda package –function-name helloworld –region us-east-1 –s3-bucket my-bucket
This will package our Lambda function code and dependencies into a zip file and upload it to the S3 bucket specified.
Once the zip file has been uploaded, we can deploy our Lambda function using the following AWS CLI command:
aws lambda deploy –function-name helloworld –region us-east-1 –s3-bucket my-bucket –s3-key helloworld.zip
This will create a new Lambda function with the code and dependencies from the zip file we uploaded.
That’s it! You’ve now successfully deployed a Lambda function using the AWS CLI.
