I have this dockerfile
Step 1: Use an official R image as a base
FROM rocker/r-ver:4.3.1
Step 2: Install system dependencies and Python dependencies in a single RUN command
RUN apt-get update && apt-get install -y
libcurl4-openssl-dev
libssl-dev
libxml2-dev
zlib1g-dev
libpng-dev
python3-pip
python3-dev
python3-venv
&& rm -rf /var/lib/apt/lists/*
Step 3: Install the R package manager renv and PyArmor in the same RUN command
RUN R -e “install.packages(‘renv’)” &&
pip install pyarmor
Step 4: Set the working directory inside the container to /app
WORKDIR /app
Step 5: Copy only necessary files (e.g., renv.lock and application files)
COPY renv.lock /app/
COPY . /app/
Step 6: Install R dependencies using renv (from renv.lock)
RUN R -e “renv::restore()”
Step 7: Set the environment variable to use the Python virtual environment
ENV PATH=“/app/venv/bin:$PATH”
Step 8: Register PyArmor and obfuscate the AnomalyDragon.py file (combine into fewer layers)
COPY pyarmor-regfile-5224.zip /app/
RUN pyarmor reg -p /app/pyarmor-regfile-5224.zip &&
pyarmor gen -r AnomalyDragon.py &&
rm -rf AnomalyDragon.py
Step 9: Expose port 3838 for Shiny app
EXPOSE 8080
Step 10: Define the command to run your Shiny app
CMD [“R”, “-e”, “shiny::runApp(‘/app’, port = 8080, host = ‘0.0.0.0’)”]
and running the conatiner through
discretekernel@TestServer:~/Latest_version_24Jun2024$ docker ps
