Dynamically Provisioning R Libraries with renv

ShinyProxy
1

Is it possible to run apps through shinyproxy with a host renv cache mount?

# the location of the renv cache on the host machine
RENV_PATHS_CACHE_HOST=/opt/local/renv/cache

# where the cache should be mounted in the container
RENV_PATHS_CACHE_CONTAINER=/renv/cache

# run the container with the host cache mounted in the container
docker run --rm \
    -e "RENV_PATHS_CACHE=${RENV_PATHS_CACHE_CONTAINER}" \
    -v "${RENV_PATHS_CACHE_HOST}:${RENV_PATHS_CACHE_CONTAINER}" \
    -p 14618:14618 \
    R -s -e 'renv::restore(); shiny::runApp(host = "0.0.0.0", port = 14618)'

Would this be the way?
