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.
| 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 |
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.
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).
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.
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.
