A Docker-based LaTeX PDF generation service using LuaTeX with AWS Lambda integration

• LaTeX with LuaTeX: Generate PDFs using LaTeX templates.
• AWS Lambda Compatible: Optimized for deployment on AWS Lambda.

• Docker installed on your local machine
• LaTeX template
• Optional for AWS lambda deployment:
  • AWS Lambda (optional for deployment)
  • AWS SecretsManager secrets with S3 access permissions: s3-access-key-id, s3-secret-access-key

1. Clone the repository:

   git clone git@github.com:mtrxsh/docker-aws-lambda-pdflatex.git

2. Pull the Docker image:

   docker pull tunatr/aws-lambda-pdflatex:v1

3. Build the Docker image:

   docker build --platform linux/amd64 -t pdflatex . --rm

4. Run the container:

   docker run --platform linux/amd64 -it -p 8080:8080 pdflatex

5. Run client (local):

try {
  let templateB64; // .tex or .zip, base64 encoded  
  let payload = {
    templateZipBase64: templateB64,
    inputFileName: "main.tex",
    outputFileName: "main.pdf",
  };
  let data = Buffer.from(JSON.stringify(payload)).toString("base64");
  const response = await axios.post(
    `http://localhost:8080/2015-03-31/functions/function/invocations`,
    {
      data,
    }
  );
  let responseData = response.data;
  console.log("Server response:", responseData);
  let result = JSON.parse(responseData.body);
  parseBase64ToFile(
    result.content,
    path.join(__dirname, "output/output.pdf")
  );
} catch (error) {
  console.error("Error calling server:", error.message);
}

6. Run client with AWS Lambda integration:

   let payload = {
     "templateBucketName": "s3_template_bucket",
     "templateObjectKey": "templates/template_folder",
     "inputBucketName": "s3_input_bucket",
     "inputObjectKey": "input/test.tex",
     "outputBucketName": "s3_output_bucket",
     "outputObjectKey": "output/test.pdf”
   };

This project was made possible with the help of the following repositories and resources:

• aws-lambda-nodejs.
• TeX Live (LaTeX/pdflatex) for AWS Lambda.
