Learn Terraform commands. The usual way to set this is filebase64sha256("file.zip") (Terraform 0.11.12 and later) or base64sha256(file("file.zip")) (Terraform 0.11.11 and earlier), where "file.zip" is the local filename of the lambda function source archive. For this example, since I used NodeJS, the format is a zip file that contains at least one ".js" file. Introduction Here we will see how to use terraform to manage lambda functions, it will be a simple hello world in node.js, available as a gist here, note that I did not create this example but itâs really close to the official documentation but shorter, you can see another example with python here. The completed terraform module can be seen here: The original body of the issue is below. Step 2: Then, weâll zip the above file into an archive named terraLambda.zip.

First of all we will just create the needed files in a new directory, and of course you are free to modify names and structure as you see fit. Terraform Template file Now that we have the code files ready lets describe the Serverless components in the Terraform scripts. I can then easily plug this .zip into my Terraform code with a 'archive_file' data block (essentially copy/pasting the zip file in my code) and reference this in my 'aws_lambda_function' resource. By Leonardo Giordani 22/03/2021 AWS infrastructure Lambda Python Terraform Share on: Twitter LinkedIn HackerNews Email Reddit Recently I started using AWS CloudWatch Log Insights and I find the tool really useful to extract data about the systems I'm running without having to set up dedicated monitoring ⦠Terraform will perform the following actions: ~ aws_lambda_function.example s3_key: "v1.0.0/example.zip" => "v1.0.1/example.zip" Plan: 0 to add, 1 to change, 0 to destroy. keyslist must be a list of strings, while valueslist can be a list of any type.

There was a bit more code, I had to write to make this test green. Create a Terraform sample template to spin an AWS EC2. Now create a file main.tf inside the directory youâre in.
