Build scripts for container definition files

This folder contains scripts and other files to create (or assist in creating) definition files needed to build Rocker container images.

Automatic update of container definition files

The Dockerfiles for pre-build images will be generated by executing the R scripts in the following order.

  1. build/scripts/generate-variables.R
  2. build/scripts/generate-args.R
  3. build/scripts/generate-matrix.R
  4. build/scripts/generate-bakefiles.R
  5. build/scripts/generate-dockerfiles.R
  6. build/scripts/clean-files.R

These scripts are run daily by GitHub Actions and automatically create a Pull Request if the run results in a variance from the default branch.

Reports of built images

Since 2021-08-10, the information of images built from this repository will be registered in the Wiki automatically.

Running make inspect-image-all (requires docker), then make report-all (requires R >= 4.1.0 and some packages) will generate reports about rocker images, in reports/ directory (ignored by git). The template for the reports is build/reports/template.Rmd and the script for giving variables to the template is ./build/knit-report.R.

The wiki HOME(Home.md) is generated from build/reports/wiki_home.Rmd.

How to control which Docker images to build

Stop building a specific R version

If you no longer need to build a particular R version, please edit the build/scripts/generate-matrix.R script and exclude that R version from the build matrix. Matrix files are reffered to in many places.

Stop building a specific image of a specific R version

Images that are not included in the groups defined in docker-bake.json files will not be built, so if you want to select images to build in each version of the stack file, edit the stack files and the make-stacks.R script to adjust the contents of groups.
