This repository provides rocker/r-ver
and its derived images,
alternate stack to r-base
,
with an emphasis on reproducibility.
Compared to r-base
, this stack:
- Builds on Ubuntu LTS rather than Debian and system libraries are tied to the Ubuntu version.
Images will use the most recent LTS available at the time when the corresponding R version was released.
- Since compatibility problems are likely to occur immediately after the release of a new Ubuntu LTS,
the version to be used is the one that is at least 90 days past release.
rocker/r-ver:4.0.0
is based on Ubuntu 20.04 (ubuntu:focal
) because no interval was set at the time of the Ubuntu 20.04 release.
- Since compatibility problems are likely to occur immediately after the release of a new Ubuntu LTS,
the version to be used is the one that is at least 90 days past release.
- Installs a fixed version of R itself from source, rather than whatever is already packaged for Ubuntu
(the
r-base
stack gets the latest R version as a binary from Debian unstable). - The only platforms available are
linux/amd64
andlinux/arm64
(arm64 images are experimental and only available forrocker/r-ver
4.1.0 or later). - Set the Posit Public Package Manager (RStudio Package Manager, RSPM) as default CRAN mirror. For the amd64 platform, RSPM serves compiled Linux binaries of R packages and greatly speeds up package installs.
- Non-latest R version images installs all R packages from a fixed snapshot of CRAN mirror at a given date.
This setting ensures that the same version of the R package is installed no matter when the installation is performed.
- In addition to CRAN mirror, the version of RStudio Server installed in
rocker/rstudio
and the date of CTAN mirror set inrocker/verse
are also fixed. Please check the document about versions for details.
- In addition to CRAN mirror, the version of RStudio Server installed in
- Provides images that are generally smaller than the
r-base
series.
Note: This repository is for R >= 4.0.0 images.
For images with R <= 3.6.3, please see the rocker-versioned
repository,
or the shiny
, geospatial
,
and binder
repositories.
The following images have been built and are available on DockerHub or GitHub Container Registry.
For more information about these container images, please see the Wiki of this repository.
Check the Rocker project site for the list of images.
Check the Wiki for the list of tags.
There are also special tags that are not listed in the wiki, devel
.
The GitHub Actions workflow build and push these images daily.
- The
devel
images are based onubuntu:latest
(the latest Ubuntu LTS version) and install the latest R-devel daily snapshot. pre-builtdevel
images are available forrocker/r-ver
,rocker/rstudio
,rocker/tidyverse
,rocker/verse
.
rocker/geospatial:dev-osgeo
is special image that differ slightly from the regular rocker/geospatial
.
Check the Rocker project site for common methods for Rocker images.
Please install R packages from source using the install.packages()
R function or the install2.r
script,
and use apt
only to install necessary system libraries (e.g. libxml2
).
Do not use apt install r-cran-*
to install R packages.
If you would prefer to install only the latest verions of packages from pre-built binaries using apt
,
consider using r-base
or rocker/r-bspm
instead.
The Docker images built from this repository describe the software installation method in standalone scripts
rather than directly in the Dockerfiles.
These files are under the scripts
directory, and these files are copied in all Docker images,
under a top-level /rocker_scripts
directory.
This allows users to extend images by selecting additional modules to install on top of any pre-built images.
For instance, if one wishes to install Shiny Server on top of a base of rocker/rstudio:4.0.0
,
one could write a simple Dockerfile as follows:
FROM rocker/rstudio:4.0.0
RUN /rocker_scripts/install_shiny_server.sh
Install scripts can generally take a version as a first argument or ingest an environment variable to specify the version to install. So to install fixed versions, one can use either of the following syntaxes:
FROM rocker/rstudio:4.0.0
ENV SHINY_SERVER_VERSION 1.5.14.948
RUN /rocker_scripts/install_shiny_server.sh
FROM rocker/rstudio:4.0.0
RUN /rocker_scripts/install_shiny_server.sh 1.5.14.948
RStudio Server and Shiny Server are managed by the S6 supervisor system, which allows containers to manage multiple background processes gracefully.
Note: No longer support ADD=
runtime triggers for installing Shiny or similar modules,
which is used for R <= 3.6.3 images.
Dockerfiles and docker-bake.json files, which define the pre-built images,
are in the dockerfiles
folder and the bakefiles
folder.
And,
these files are generated by the build scripts under the build
folder.
When a new version of R or RStudio is released, GitHub Actions will automatically create a Pull Request to update these files.
Latest R version images will be built on a rolling basis; when the Dockerfiles are updated, they are immediately built by GitHub Actions.
Non-latest R version images will be built when a new R version is released. At this time, a tag and a GitHub release will also be created.
