Can I use wkhtmltopdf on AWS Lambda

Question

Greeting,

I'm using a AWS Lambda function to merge PDF files stored on S3. In addition to that, I need now to create a PDF file (from HTML and CSS). I was trying to use wkhtmltopdf, but it seems that I would have to install it using apt-get install (which I don`t think I have access on AWS Lambda).

Any ideas on how can I do it?

Any suggestions for wkhtmltopdf replacements?

Thanks!

Answer 1

There are multiple projects on GitHub claiming to run wkhtmltopdf on Lambda. Here are a few.

• https://github.com/lubos/aws-lambda-wkhtmltopdf
• https://github.com/dimiro1/lambda-wkhtmltopdf
• https://github.com/jpaolin/aws-lambda-s3-wkhtmltopdf

Include the wkhtmltopdf binary and making sure it has execution permission(chmod 755). Add the binary path to your language runtime. e.g. with nodejs

process.env['PATH'] = process.env['PATH'] + ':' + process.env['LAMBDA_TASK_ROOT'] + '/bin/linux';
