Update results in deletion of all install package...

[tsoruu]

Hello, I notice some quirks when using Rocker with services like WatchTower that update the container to use the latest image... It basically cleans all of the RStudio to a new, out-of-the-box state... Is there:

• An update procedure that doesn't remove all install R packages?
• A way to bind volumes so packages didn't get deleted after the update?
• A way to preserve the dependency installed (Linux libraries that some R packages needed to run)?

I'm using Rocker to share my server with my colleague, two instances have to be able to be run simultaneously, binding the dependency to the host machine would not work (I think) as the R environment will be shared between me and my colleague, or is it okay to do so?
Help would be really appreciated.
