anyone have a modern container workflow for the serverless framework?

I was able to find code that executed at one point in time. It no longer does. I’d really like to instead get fresh or deno into a container and use serverless to make it work on aws. this is at least as of current a requirement for all code at my workplace and is a hard must to hit production with deno.

Specifically getting it working with serverless framework ; the terminology in this space is HORRENDOUS

You can use the image and docker file to deploy using Serverless framework http://serverless.com//blog/container-support-for-lambda https://github.com/hayd/deno-lambda/tree/master/example-serverless We usted to have deno api running on AWS LAMBDA with the combination of this articles and a more simplier Serverless yml

Give it a read to the repository and the article it was pretty simple, we moved to deno deploy due the lower cold starts, thats why currently i dont have an example, let me know if u cant to try to setup a basic example

Unfortunately I have a codified requirement to utilize serverless for 100% of AWS infra at my company 😭 There’s hardline requirements for access to internal networks no meshing nothing allowed

Let me know if it helps But in short: Define serverless.yml | .ts | .js

// serverless.js (you can use yml also)
const name = "deno-lambda-test";
let config = {
  service: name,
  provider: {
    name: "aws",
    ecr: { images: { [name]: { path: "./" } } },
  },
  functions: {
    service: {
      image: { name },
      events: [{ httpApi: "*" }],
    },
  },
};
module.exports = config;

  },
  functions: {

      events: [{ httpApi: "*" }],
    },
  },
};
module.exports = config;

Define Dockerfile

//Dockerfile
FROM hayd/deno-lambda:1.29.1

COPY . .
RUN deno cache lambda.ts

CMD ["lambda.handler"]

Define handler

//lambda.ts
import {
  APIGatewayProxyEventV2,
  APIGatewayProxyResultV2,
  Context,
} from "https://deno.land/x/lambda@1.28.3/mod.ts";

const handler = async (
  event: APIGatewayProxyEventV2,
  context: Context
): Promise<APIGatewayProxyResultV2> => {

  return {
    body: JSON.stringify({
      message: "hello-world"
    }),
    headers: {
      "content-type": "application/json",
      "Access-Control-Allow-Origin": "*",
    },
    statusCode: 200,
  };
};

export { handler };
