Simple Dockerfile for R

Dockerfile

## Base image
FROM rocker/r-base

# Copy R scripts to container
COPY / ./

# Execute when container is BUILT:
# sudo docker build -t example_container .
RUN Rscript setup.R

# Execute when container is RUN:
# sudo docker run --rm example_container
CMD Rscript run.R

run.R

print("I built a container!")

setup.R

print("I am building a container.")

My first swag was just

FROM rocker/r-base
RUN R -e 'print("I am building a container.")'
CMD R -e 'print("I built a container!")

but that seems a bit hard to extrapolate from. :)

Or, for my very favorite @jtbaker:
echo -e "FROM rocker/r-base\n COPY / ./\n CMD Rscript run.R" >> Dockerfile && echo "print('I love you, Jason')" >> run.R && docker build -t ex . && docker run --rm ex
