TheRockstar RStudio Dockerfile inherits fromrocker/rstudio and contains the following:

• rJava: Low-Level R to Java Interface andOpenJDK 11
• drat: 'Drat' R Archive Template
• RJSONIO: Serialize R Objects to JSON, JavaScript Object Notation
• packrat: A Dependency Management System for Projects and their R Package Dependencies
• xml2: Parse XML
• roxygen2: In-Line Documentation for R

Rockstar is used by theRCOBOLDI (R COBOL Data Integration) Package, which is an R package for importing COBOL CopyBook data into the R Project as data frames.

Rockstar can also be helpful for data scientists or data engineers who need to use R with rJava. The rJava package can be slightly involved to set up and the Rockstar RStudio Dockerfile will help you get past this. The Rockstar RStudio Dockerfile can also act as a referece for engineers that need to configure rJava with a JDK or JRE.

TheRockstar project can be found onGitHub andRockstar images can be found onDockerHub. Below we include instructions for installing the Rockstar RStudio image and then creating a container from this image.

docker pull thospfuller/rockstar-rstudio:[latest or 1.0.0 or some other tag]

then

docker image ls

should show something like this:

> REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE> thospfuller/rockstar-rstudio   latest              f8c59f41e2d7        41 minutes ago      3.16GB

then

docker run -d -p 8787:8787 -e PASSWORD=password --name rstudio -i -t f8c59f41e2d7

Next, browse tohttp://localhost:8787 and enter the username 'rstudio' and password 'password' and you should see the following.

An example of a container created from the Rockstar RStudio docker image running on localhost:8787.
