Create Lambda functions layers in simple way.

Lambda Layer Creation

This repository provides a shell script to create a Lambda layer using Docker. The script builds a Docker image based on the provided Dockerfile and requirements.txt, and then runs a Docker container to create the layer. Finally, it moves the layer.zip file to the specified directory.

Prerequisites

• Docker installed and properly configured on your system.

Usage

1. Clone or download this repository to your local machine.

2. Open the create_layer.sh file in a text editor.

3. Set the DIRECTORY variable to the path where your Dockerfile and requirements.txt files are located.

4. Set the LAYER_NAME variable to the name you want to give your layer by default, it's layer.

5. Add all the required pachages in requirements.txt and save it.

6. Save the changes.

7. Open a terminal or command prompt and navigate to the directory where the create_layer.sh script is located.

8. Make the script executable by running the command: chmod +x create_layer.sh.

9. Run the script: ./create_layer.sh.

10. The script will build the Docker image, run the container to create the layer, move the layer.zip file to the specified directory, and clean up by removing the Docker image.

11. After running the script, you should find the layer.zip file in the specified directory. You can then upload it to AWS Lambda as a layer and attach it to your Lambda functions as needed.

Note

• Please ensure that you have Docker installed and configured properly on your system before running the script.

• Make sure to include the necessary requirements.txt file in the directory specified by the DIRECTORY variable. The script will install the Python packages listed in requirements.txt and include them in the Lambda layer.

• You may need to modify the Dockerfile or requirements.txt based on your specific requirements.
