Nsjail - description taken from github:

Example Dockerfile for hosting a CTF task:

FROM disconnect3d/nsjail

RUN apt-get update && apt-get install -y \
    gcc g++

MKDIR /task
WORKDIR /task
ADD . /task
RUN g++ task_code.cpp -o task_exec && rm task_code.cpp

Then you can launch your container e.g. with such command:

docker run --privileged <yourimage> nsjail -Ml --port 3001 --user 99999 --group 99999 --disable_proc --chroot /task --time_limit 15 -R /lib/ -R /lib64/ -R /usr/bin/ /task_exec
