Dockerfile Oracle

Does anyone have a current Dockerfile that works with Oracle they could share?

We are continually struggling to get a Rmd file to run correctly. We keep getting various java.lang errors which I’m guessing have to do with the Oracle connection which is using RJDBC and rJava. During the build process I’m not getting an errors related to them.

In my Dockerfile I used curl to install the ODBC for my Linux distro when connecting to a MS SQL database. You could probably do something similar and install the JDBC driver from Microsoft using curl.

Thanks, that’s something I’ll look at.

Dockerfile that worked for connecting to Oracle, CMD javareconf is very important.

Dockerfile:

VERY IMPORTANT to set java environment for R

CMD javareconf

install needed R packages

RUN R -e “install.packages(c(‘shiny’), dependencies = TRUE, repo=‘https://cloud.r-project.org’)”
RUN R -e “install.packages(c(‘flexdashboard’, ‘dplyr’, ‘rJava’, ‘RJDBC’, ‘readr’, ‘DT’, ‘lubridate’, ‘rmarkdown’), dependencies = TRUE, repo=‘https://cloud.r-project.org’)”

make directory and copy Rmarkdown flexdashboard file in it

RUN mkdir -p /prmc
COPY prmc/PRMC.Rmd /prmc/PRMC.Rmd
COPY prmc/prmc.sql /prmc/prmc.sql

COPY prmc/ojdbc11.jar /prmc/ojdbc11.jar

Copy Rprofile.site to the image

COPY Rprofile.site /usr/local/lib/R/etc/

make all app files readable (solves issue when dev in Windows, but building in Ubuntu)

RUN chmod -R 755 /prmc

expose port on Docker container

EXPOSE 3838

run flexdashboard as localhost and on exposed port in Docker container

CMD [“R”, “-e”, “rmarkdown::run(’/prmc/PRMC.Rmd’, shiny_args = list(port = 3838, host = ‘0.0.0.0’))”]
