Description

Create a Dockerfile from an renv.lock file

Usage

dock_from_renv(
  lockfile = "renv.lock",
  distro = NULL,
  FROM = "rocker/r-base",
  AS = NULL,
  sysreqs = TRUE,
  repos = c(CRAN = "https://cran.rstudio.com/"),
  expand = FALSE,
  extra_sysreqs = NULL,
  use_pak = FALSE,
  user = NULL,
  dependencies = NA,
  sysreqs_platform = "ubuntu",
  renv_version
)

Arguments

lockfile

Path to an renv.lock file to use as an input..

distro

• deprecated - only debian/ubuntu based images are supported

FROM

Docker image to start FROM Default is FROM rocker/r-base

AS

The AS of the Dockerfile. Default it NULL.

sysreqs

boolean. If TRUE, the Dockerfile will contain sysreq installation.

repos

character. The URL(s) of the repositories to use for options("repos").

expand

boolean. If TRUE each system requirement will have its own RUN line.

extra_sysreqs

character vector. Extra debian system requirements. Will be installed with apt-get install.

use_pak

boolean. If TRUE use pak to deal with dependencies during renv::restore(). FALSE by default

user

Name of the user to specify in the Dockerfile with the USER instruction. Default is NULL, in which case the user from the FROM image is used.

dependencies

What kinds of dependencies to install. Most commonly one of the following values:

• NA: only required (hard) dependencies,

• TRUE: required dependencies plus optional and development dependencies,

• FALSE: do not install any dependencies. (You might end up with a non-working package, and/or the installation might fail.)

sysreqs_platform

System requirements platform.ubuntu by default. If NULL, then the current platform is used. Can be : "ubuntu-22.04" if needed to fit with the FROM Operating System. Only debian or ubuntu based images are supported

renv_version

character. The renv version to use in the generated Dockerfile. By default, it is set to the version specified in the renv.lock file. If the renv.lock file does not specify a renv version, the version of renv bundled with dockerfiler, specifically 1.0.3, will be used. If you set it to NULL, the latest available version of renv will be used.

Details

System requirements for packages are provided through RStudio Package Manager via the pak package. The install commands provided from pak are added as RUN directives within the Dockerfile.

The R version is taken from the renv.lock file. Packages are installed using renv::restore() which ensures that the proper package version and source is used when installed.

Value

A R6 object of class Dockerfile.
