edence/rcore repository overview

⁠rcore

This repository houses the source code for the edenceHealth⁠ Docker image edence/rcore⁠. This image is used as the base for many of our containers which require the R programming language⁠.

Built on the current Debian "stable" release, this image includes essential R packages (r-base-dev, r-recommended, and r-cran-remotes) from the distribution, alongside the Temurin JDK⁠.

⁠"nonroot" reduced privilege user account

For improved runtime security, this image includes a nonroot user account, which aligns with the UID and GID used by the Google "distoless"⁠ images. This user account can be implemented in child images by using the USER nonroot Dockerfile directive or via the --user / -u docker run arguments.

⁠Utility Programs

The image includes the following utility programs intended for use by downstream consumers:

⁠"txt2lock" lockfile generation helper

txt2lock.R is a utility that generates renv.lock files from renv.txt files. An renv.txt file is a list of package specifications, one per line, as provided to renv::install. This allows a loose list of package requirements to generate a much more specific renv.lock file, which contains exact package version numbers/specifications for all dependencies. The program generates the renv.lock file by calling renv::snapshot with snapshot.type="all".

⁠"patch4ref" patch script runner

patch4ref is a utility for executing patch scripts, using a GIT_REF environment variable as a reference. The script is included from: https://github.com/edencehealth/patch4ref/⁠.
