can not find deno with https://github.com/lambci/docker-lambda?

[davidxiao]

hi,
I tried to play this with local lambda, while getting the below error:

111 #### PATH=/var/task/bin:/usr/local/bin:/usr/bin/:/bin:/opt/bin
222 #### pwd=/var/task
/var/task/bootstrap: line 238: deno: command not found

line 238 is below line, i tried to echo out the path and pwd
https://github.com/hayd/deno-lambda/blob/master/runtime/bootstrap#L236

reckon if it's related to lambda image ? because that deno can not run in Mac as well

BTW, what is https://github.com/hayd/deno-lambda/releases/download/1.0.2/amz-deno.gz and what it's for?

yeah, i downloaded deno-lambda-layer.zip and unzipped it, then ran in the dir with unzipped files:
docker run -d -e DOCKER_LAMBDA_STAY_OPEN=1 -p 9001:9001 -v "$PWD":/var/task:ro,delegated lambci/lambda:provided handler

bootstrap was running, so got the error message from bootstrap, the only thing I can think of now is reckon it's related to lambda OS?

Ah, got it:

The layer must be added as a layer (mounted at /opt)! Whilst the app itself is at /var/task. So, you can do the following:

❱ docker run -it --rm -v "$PWD":/var/task:ro,delegated -v "$PWD":/opt:ro,delegated lambci/lambda:provided hello.handler
START RequestId: c95f0609-b763-183e-56f2-22e72c2dae99 Version: $LATEST
END RequestId: c95f0609-b763-183e-56f2-22e72c2dae99

{"statusCode":200,"headers":{"content-type":"text/html;charset=utf8"},"body":"Welcome to deno 1.0.2 🦕"}

Using stay open:

❱ docker run -e DOCKER_LAMBDA_STAY_OPEN=1 -p 9001:9001 -it --rm -v "$PWD":/var/task:ro,delegated -v "$PWD":/opt:ro,delegated lambci/lambda:provided hello.handler
Lambda API listening on port 9001...

in another shell:

❱ aws lambda invoke --endpoint http://localhost:9001 --no-sign-request --function-name deno-func --payload '{}' output.json
{
    "StatusCode": 200,
    "ExecutedVersion": "$LATEST"
}
❱ cat output.json
{"statusCode":200,"headers":{"content-type":"text/html;charset=utf8"},"body":"Welcome to deno 1.0.2 🦕"}

It probably makes sense to store the layer in a separate directory.

yeah, sorry for late response, just had chance come now, can close the ticket
