How do I use trillium-aws-lambda?

[mathiversen]

Hello,

I'm struggling a bit to understand how build and deploy on aws, and I'm not sure if I'm doing something wrong or there's in fact a bug preventing the runtime from executing. In short I do the following:

1. I add x86_64-unknown-linux-musl to rustup & installed musl-gcc
2. I successfully build with the above target
3. I name the executable bootstrap and zip it (and make sure the only file is the build file called bootstrap)
4. I login to aws and create a function, I've tried both of the custom runtimes but I get the same error;

"errorMessage":"RequestId: xxx Error: fork/exec /var/task/bootstrap: no such file or directory",
"errorType":"Runtime.InvalidEntrypoint"

I started on a tutorial just to document what i was doing: link maybe that's something worth adding to the project?

It has been a bit since I have tried this myself, but this deploy script is how I was building and deploying the aws-lambda-example app, but I'm not sure if documenting lambda best practices is really in scope for this project, as there are many valid workflows for lambda, and the parts that are unique to trillium end at building a binary

Yeah i saw the script and that should probably be enough for most people. I just walked through the process to try and figure out what i was doing wrong. I saw that you made some updates to the code, did you try and run it on aws as well?

Seems like aws have an official runtime so it's probably a good idea to replace lamedh_runtime with lambda_runtime. @jbr

I managed to build working lambda executable with cross. But when I tried it with trillium i got the following error:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error("data did not match any variant of untagged enum
LambdaRequest", line: 0, column: 0)', /cargo/registry/src/github.com-1ecc6299db9ec823/trillium-aws-lambda-0.2.0/src/lib.rs:88:10

I took a stab at creating my own aws_lambda based on the official runtime. It's not working yet, and I'm trying to debug the last step. It's a pretty good learning opportunity. Feel free to have a look: https://github.com/mathiversen/sessile-aws-lambda @jbr
