Dear all,


I wanted to run OpenFOAM simulation inside docker container, for this I have built the docker image from dockerfile. The dockerfile has Openfoam 5 installation along with necessary requirements.


1. When the image is built, OpenFOAM works perfectly when I enter into the container and test with "icoFoam" command.


2. But, when I exec it with "CMD" inside dockerfile, it throws an error stating "icoFoam not found".


3. All installation done with new user and not in root.


Below is the dockerfile content.

###################################################################################

   

USER root

# Install OpenFOAM5.0, paraviewopenfoam54 and PyFoam
 # Add dl.openfoam.org to the list of software repositories


 RUN sh -c "wget -O - http://dl.openfoam.org/gpg.key | apt-key add -"


 # Install the dependancies (Can also have a requirements file and build from there)


 RUN apt-get install software-properties-common -y
RUN add-apt-repository http://dl.openfoam.org/ubuntu
RUN apt-get install apt-transport-https -y
 
RUN apt-get update -y
 
RUN apt-get -y install openfoam5


# New user creation
RUN groupadd -r sunag && useradd -m -r -g sunag sunag

# Source bashrc
RUN echo "source /opt/openfoam5/etc/bashrc" >> /home/sunag/.bashrc

USER sunag

# Install pip packages for specific user
RUN python -m pip install --user numpy scipy pandas scikit-image opencv-python PyFoam open3d numpy-stl gunicorn


WORKDIR /home
CMD icoFoam

4. The CMD command when docker image is run, throws "icoFoam not found", but when the entering the container and running icoFoam, it works perfectly.


So, what am I missing here or what work around needs to be done?


Hope, it is understood.
