Create a dockerfile from an renv.lock file — dk_from_renv • dockitect

Generates a dockerfile based on an renv.lock file, ensuring reproducible package dependencies in the container.

Usage

dk_from_renv(
  lock_file = "renv.lock",
  r_version = NULL,
  base_image = NULL,
  include_sysreqs = TRUE
)

Arguments

lock_file: Path to renv.lock file
r_version: R version to use (default: from lock file)
base_image: Base image to use (default: determined from R version)
include_sysreqs: Include system requirements (default: TRUE)

Value

A dockerfile object configured based on the renv.lock file

Details

This function:

Extracts the R version from the lock file (if available)
Uses the appropriate rocker/r-ver base image
Adds system requirements for the packages in the lock file
Sets up renv and restores the packages from the lock file

The resulting dockerfile will recreate the exact environment specified in your renv.lock file, ensuring reproducible results.

# Create a dockerfile from an renv.lock file
df <- dk_from_renv("renv.lock")

# Specify a different R version
df <- dk_from_renv("renv.lock", r_version = "4.4.0")
} # }
