go-wkhtmltopdf-lambda

Run wkhtmltopdf in AWS Lambda

Not maintained for now, but mainly an example of how to use go-wkhtmltopdf on Lambda.

Uses https://github.com/SebastiaanKlippert/go-wkhtmltopdf to generate PDF files from JSON input.

Usage

• Create a Golang AWS Lambda function in the AWS console or using the AWS CLI
• As source, use the lambda.zip file from a release, this includes the latest version of wkhtmltopdf
• The Handler name is go_wkhtmltopdf_linux
• If you want to build your own version, make sure you build the go executable for Linux (GOOS=linux) and make it executable (chmod +x)
• Create an S3 trigger for you Lambda function (using suffix .json is recommended)
• Make sure your IAM Lambda role has S3 Read and Write access to your bucket
• Create a JSON file from the PDF generator, following the instructions at https://github.com/SebastiaanKlippert/go-wkhtmltopdf#saving-to-and-loading-from-json
• Upload the JSON to the S3 bucket you chose in your Lambda trigger
• The PDF is saved in the same bucket with extension .pdf added to the original filename
