Description

I have several devcontainer features that I frequently use, available at https://github.com/MiguelRodo/DevContainerFeatures. The two main ones included in this collection are:

• repos — Installs a utility to easily clone and set up multiple Git repositories from a single, simple repos.list file.
• renv-cache — builds and installs R packages from renv.lock during container build into a global renv cache that persists past the container build and is automatically available to R analyses. This improves container start time and ensures package state is more easily restored in the future.

I am not aware of an alternative to the repos feature. The renv-cache feature is quite distinct from the rocker renv-cache feature, which does not install packages into a cache during container build time.

It also has three other, more minor features:

• apptainer — Installs Apptainer.
• mermaid — Installs the Mermaid CLI.
• fit-sne — Installs FIt-SNE, an efficient implementation of t-SNE.

I highly doubt an equivalent to fit-sne is available, and I could not see anything that obviously set up mermaid or apptainer.
