Hi @GangWar   This is what I was aiming at.   My current Dockerfile roughly looks as follows:   #Dockerfile FROM docker.repository.cloudera.com/cdsw/engine:10 WORKDIR /tmp ENV R_HOME=/usr/local/lib/R RUN wget http://cran.rstudio.com/src/base/R-3/R-3.6.3.tar.gz && \ tar xvf R-3.6.3.tar.gz && \ cd R-3.6.3 && \ ./configure --prefix=/usr/local --enable-R-shlib && \ make && \ make install && \ rm -rf /usr/local/bin/R && \ rm -rf /usr/local/bin/Rscript && \ ln -s /usr/local/lib/R/bin/R /usr/local/bin/R && \ ln -s /usr/local/lib/R/bin/Rscript /usr/local/bin/Rscript && \ echo -e "# make libR.so visible to ld.so\n/usr/local/lib/R/lib" > /etc/ld.so.conf.d/libR.conf && \ ldconfig && \ cd .. && \ rm -rf R-3.6.3.tar.gz && \ rm -rf R-3.6.3 # the java installation is mounted at CDSW session run time - copy it to the build context here COPY ./java /usr/lib/jvm/java-openjdk RUN export JAVA_HOME=/usr/lib/jvm/java-openjdk && \ R CMD javareconf RUN Rscript -e "update.packages(checkBuilt=TRUE, ask=FALSE, repos='https://cloud.r-project.org')" # remove java installation again since it is mounted at runtime RUN rm -rf /usr/lib/jvm   I am successfully able to launch CDSW sessions with this container with the following editors: Workbench - Python Workbench - Scala RStudio Jupyter Notebook (even with IRkernel) The issue remains though, that launching a session with the Workbench - R editor is not possible. The session is immediately exited and the following error visible in the log: ... PID of main R process is 205 PID of parser R process is 207 R has exited with code 2 and signal null Exiting with code 2 ...   Using the base image which works with the Workbench - R editor, I checked which processes CDSW tries to launch in this case. These are the following two: cdsw 197 51 0 08:29 ? 00:00:00 /usr/local/lib/R/bin/exec/R --sense --no-readline --args cdsw 198 51 0 08:29 ? 00:00:00 /usr/local/lib/R/bin/Rserve --RS-socket /tmp/cdsw-rserve-x0jbdet9dfe1428o.sock --RS-source /usr/local/lib/node_modules/r-engine/lib/parse.utils.r --slave   Using my own image and a Workbench - Python session, I was able to successfully execute these two processes.   Process 1: bash$ /usr/local/lib/R/bin/exec/R --sense --no-readline --args WARNING: unknown option '--sense' R version 3.6.3 (2020-02-29) -- "Holding the Windsock" Copyright (C) 2020 The R Foundation for Statistical Computing Platform: x86_64-pc-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.
