As said here: https://github.com/ThinkR-open/golem/issues/282#issuecomment-891118964

A new test today with a combination of {renv} and Docker cache requires:

• a .dockerignore with renv and .Rprofile ignored as suggested by jcpsantiago :

.RData
.Rhistory
.git
.gitignore
manifest.json
rsconnect/
Rproj.user
.Rprofile
renv/

• A Dockerfile like this that forces {renv} to use the classical path to install dependencies with renv::restore(library = .libPaths()):
  • Remember to create the dockerfile when you are in your package, with renv::status() up-to-date, so that currently installed versions are the same as in "renv.lock"
  • Note that sub-dependencies probably still don't have the correct version and will be re-installed by renv::restore()
  • Note also that when you change some code in your project, then renv::restore() will be called again as it appears after WORKDIR

That should be good now.
