Build a new Docker image

Edit me

The following is an example of how to update the DAFoam repo in Docker and save it as a new Docker image. First, create a file called Dockerfile, copy and paste the following commands into Dockerfile, and run docker build -t my_new_dafoam_image_name .. Here “dafoam/opt-packages:latest” can be any existing Docker image.

FROM dafoam/opt-packages:latest

# Swith to dafoamuser
USER dafoamuser

# compile
RUN . /home/dafoamuser/dafoam/loadDAFoam.sh && \
    cd $DAFOAM_ROOT_PATH/repos && \
    git clone https://github.com/mdolab/dafoam && \
    cd dafoam && \
    export export COMPILE_DAFOAM_ADF=1 && \
    ./Allmake
