Using R on AWS Lambda

I assume that the R script in the Lambda has access to the AWS OS it's running on so theoretically it could use for example Clodyr's R library aws.s3 and fetch files from s3.
# get file as raw vector
get_object("mtcars.Rdata", bucket = "my_bucket")
Then you don't have to pass it thru Python and also you avoid rewriting your existing R code base. Or am I missing something? Is this not possible?
Hello,
Very nice job!
I'm confused about EC2. Reading your documentation, I can't figure out why do I need a EC2 instance to build the package. Is it possible to do that locally? Is there some reason for that?
As I understand, after setting up all variables, I just need to run 01_main.sh script, right?
Best regards,
Clovis
Hi
in script 24-setup_lambda.sh I cant seem to be able to create the Lambda Authorizer Function.
It fails with the following (the permissions for the IAM user running this are full access to lambda)
INFO : Creating Lambda Authorizer Function ...
An error occurred (InvalidParameterValueException) when calling the CreateFunction operation: The role defined for the function cannot be assumed by Lambda.
An error occurred (ResourceNotFoundException) when calling the GetFunctionConfiguration operation: Function not found: arn:aws:lambda:ap-southeast-2:11111111111:function:aws-lambda-r-lambda-authorizer

On the Amazon AMI I can install from inside R, but then I have this problem:
Installing package into ‘/usr/lib64/R/library’
(as ‘lib’ is unspecified)
Warning in install.packages("jsonlite", repos = "http://cran.r-project.org") :
'lib = "/usr/lib64/R/library"' is not writable
Would you like to use a personal library instead? (y/n)
I can install it this way also:
wget https://cran.r-project.org/src/contrib/jsonlite_1.5.tar.gz
sudo R CMD INSTALL jsonlite_1.5.tar.gz
which probably is the best way, or run R as sudo..

one thought is that perhaps my custom ami is not right, or perhaps a bug somewhere?

formatI think the tooling has improved considerably and its fairly straightforward to compile binaries within a docker image without having to spin up an ec2. I'm considering using this for working with some of my colleagues that work exclusively in R and was hoping to make it as easy and painless as possible for them to get an RScript scraper deployed with precompiled binaries
I used this repo to build some python library binaries in the past: https://github.com/AlJohri/aws-lambda-lxml. the whole thing boiled down to:
docker run -v $(pwd)/"$version/py36/":/outputs -it lambci/lambda:build-python3.6 pip install lxml=="4.2.4" -t /outputs/
tar -czvf "4.2.4/py36/lxml-4.2.4.tgz" "4.2.4/py36/lxml"
aws s3 cp 4.2.4/py36/lxml-4.2.4.tgz s3://mybucket/lambda-compiled-binaries/py36/
see build.sh
would you consider a PR switching to docker instead of ec2?
Great project!
I am trying to configure the setup_user.sh script file by following the example file.
I added:
#!/bin/bash
# user settings and secrets
# customize and rename to `setup_user.sh`
# overwrites `secrets_default.sh`, `settings_default.sh`, `setup_auto.sh`
PRJ_NAME ="myproj"
PRJ_BRANCH="myproj"
Then I run scripts/01_main.sh
Got error:
\e[32mINFO :\e[39m Checking project directories
\e[32mINFO :\e[39m Loading default settings and secrets
/Users/macos/Documents/r-ec2/myproj/settings/setup_user.sh: line 6: PRJ_NAME: command not found
\e[31mERROR:\e[39m PRJ_NAME is \e[95mMISSING\e[39m. Exiting.
Is there a simple way to configure the setup_user script?
