An r-ver image with extra build dependencies

BuildR Docker Images

This is a series of Docker images, based on the excellent rocker/r-ver images, that are useful for CI builds in R projects. The general plan is that all system dependencies you might need for an R package build are already in, and you are able to install R dependencies as required. The buildr-reticulate image also adds an Anaconda version that is roughly contemporary with the R version.

Images are built here and pushed to Docker Hub.

Images

Image	Docker Hub	Description
buildr	buildr	Adds some system dependencies and the R remotes package. Otherwise it's plain R
buildr-tidyverse	buildr-tidyverse	Tidyverse can take 20 minutes to build in Linux so you can have a version that already has it
buildr-reticulate	buildr-reticulate	Adds Python and Conda to buildr-tidyverse along with reticulate
buildr-rmd	buildr-rmd	Adds rmarkdown (and bookdown/pagedown) to buildr-reticulate along with Chrome for chrome_print

Add a new version

The builds happen in GitHub actions. The branch name is used everywhere as the tag. However, there is still some manual effort I haven't been able to remove.

1. Create a new branch

When R is upgraded and a new r-ver image is available you can make a new branch. Start from the highest branch number (or master). It should be the R version with no other characters (eg. 3.6.3).

2. Up version all tags

I haven't been able to use ARGS as I'd like in Dockerfiles so you have to go through every docker file and bump up the tag in the top FROM line. eg:

FROM rocker/r-ver:3.6.3

Github actions will take care of the output tag, so long as your branch name is right.

3. Push branch

On pushing the new branch GitHub actions will kick in, build all the images and push them to Docker hub. You can now use the new R version. You can merge onto master if you like but don't delete the branch.
