Needed to set environment variables

[TomNicholas]

I got the first example to run :champagne:

python examples/lithops-add-asarray.py "s3://cubed-$USER-temp" cubed-runtime

But to get it to run on AWS (I don't have a Modal account) I did have to export some environment variables that weren't documented (thank you @yuvipanda):

AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_DEFAULT_REGION

I also had to use sudo for some docker commands.

Glad it worked!

We can update the docs to mention those environment variables.

Was this when running lithops runtime build or something else?

Another thing that's missing from the docs is setting ulimit

ulimit -n 1024

I found I needed this for running the larger lithops examples.
