To create an AWS Lambda function using Terraform, you need to define the necessary resources in a Terraform configuration file. Here’s an example of how you can create a Lambda function using Terraform:
Option 1 - Seperate Lambda Source
- Create a new directory for your Terraform configuration and navigate to it in your terminal.
- Create a new file with a
.tfextension, such as
lambda.tf, and open it in a text editor.
- In the lambda.tf file, add the following code:
- In the above code, you can customize the following parts:
region: Specify the AWS region where you want to create the Lambda function.
runtime: Specify the runtime environment for your Lambda function (e.g.,
filename: Update the path to your Lambda function code. Ensure that the code is packaged in a ZIP file.
You can also modify the environment variables section (
VALUE) according to your requirements.
Initialize the Terraform configuration by running the following command in your terminal:
- Once the initialization is complete, you can create the Lambda function by running the following command:
Terraform will analyze the configuration, prompt for confirmation, and then create the necessary resources, including the Lambda function.
Option 2 - Inline Lambda Source
An inline Lambda function means that the function code is defined directly in the Terraform configuration file instead of referencing an external code file. Here’s an example of how you can create an inline Lambda function using Terraform:
- Follow steps 1 and 2 from the previous answer to set up your Terraform configuration.
- In the
lambda.tffile, add the following code:
- Customize the code as needed, such as the
runtime, and environment variables.
- Save the
- Initialize the Terraform configuration by running
terraform initin your terminal.
- Once the initialization is complete, create the Lambda function by running
Terraform will analyze the configuration, prompt for confirmation, and create the inline Lambda function using the code provided in the
That’s it! You have now created an inline Lambda function using Terraform.
