We're currently running into a resource problem with our API Gateway and stumbled upon this plugin. I can't really figure out how to use this exactly, though. Can you please provide more information or an example of actually using this in this repo?

Thanks!

Updated readme. You can use you existing serverless yml file to test

Let me know if you run into problem after sls deploy

Rukenshia commented 6 years ago

Deployment doesn't work, getting a heap error:

This plugin does heavy computation on serverless cloud-formation.json (Need to work on)

Currently I'm testing on 4GB RAM, and works fine. on how much memory you are testing with?

Rukenshia commented 6 years ago

We've tested it on a machine with 32GB of RAM. it seems like node is hitting some limit here as the machine still has ~10GB ram free, node taking up up to 1.5GB

AndrewBarba commented 6 years ago

You can run with node directly and the max_old_space_size option to use more ram:

node ./node_modules/serverless/bin/serverless --max_old_space_size=4096 deploy
