⁠AWS Lambda R Runtime

This Dockerfile implements a custom R runtime for AWS Lambda containers as described here⁠.

⁠Usage

To use your R functions with this container, simply create a new Dockerfile and use:

FROM jsinghm/aws-lambda-r:latest

as the base container. Then, create an R file with the function(s) you want to call, i.e.

# myfunctions.R
r_lambda_call <- function(arg) {
    list("passed" = as.character(arg))
}

and COPY the R file into the $LAMBDA_TASK_ROOT in your container:

# Dockerfile
COPY myfunctions.R ${LAMBDA_TASK_ROOT}/

Now just add a CMD line with the corresponding file.function syntax:

# Dockerfile
CMD ["myfunctions.r_lambda_call"]

An example of the full custom Dockerfile is:

FROM jsinghm/aws-lambda-r:latest

COPY myfunctions.R ${LAMBDA_TASK_ROOT}/

CMD ["myfunctions.r_lambda_call"]
