To deploy a Julia program on AWS Lambda currently involves making a custom Docker Image. Recently, Amazon announced the ability to create a Custom Runtime , which lowers the barrier to entry. However, their tutorial is quite lacking and they mostly seem to be partnering with companies ? Does anyone k…

The link doesn’t work for me.

Sorry, I didn’t realize the project was private. I’ve made it public now.

Current issues still being worked on: Telling Julia where to find packages Resolving bugs we haven’t noticed yet…

I would be relly interested in hearing more about your (and others’) experiences. I understand you weren’t quite successful in the end @Seanny123 ? What were the remaining problems? How did it work apart from these?

We got Hello World going, but communication was impossible due to being unable to import Http.jl. It existed. It seemed to be in the expected place, however Julia could not find it.

Has anyone had any more luck with this yet? I have been using samoconnor/AWSLambda.jl but would like to use my Julia1. code.

I’ve been working on this a bit using your code as a start @Seanny123 . The main problem I’ve run into is the AWS limit on the size of the zip. The runtime zipped is ~70MB, but AWS requires a max of 50MB. Were you able to shrink the size down any further?

I thought AWS Lambda “layers” had different limits than functions? I think that’s why we were able to run our layer despite the larger size.

Hmmm, yeah, that’s what I thought too. But aws lambda publish-layer-version --layer-name julia-runtime --zip-file fileb://packaging/julia-v1.zip An error occurred (RequestEntityTooLargeException) when calling the PublishLayerVersion operation: Request must be smaller than 69905067 bytes for the …

Actually, this limit seems to be for direct zip-upload only. The limit is removed if we put the zip file in s3 and point to the zip file in s3.

Just to update here, looks like this is now possible (see [ANN] AWS Lambda Julia runtime and Running AWS Lambda functions with Julia | Tom Kwong - YouTube)
