I've seen a few other posts about the same issue, but no clear solution from any of them.

When running docker build -t test-shiny ., I get the following error when running the docker image locally:

Error in library(leaflet) : there is no package called ‘leaflet’
Calls: <Anonymous> ... sourceUTF8 -> eval -> eval -> ..stacktraceon.. -> library
Execution halted

Here is my Dockerfile:

I know I am installing a lot of r packages, but my app runs fine in RStudio. After reading this post, I already tried adding the solution from the accepted answer, but unsuccessful. Any suggestions or solutions would be much appreciated.
