Dockerfile

### Welcome to CS 165 Docker Procedure
#   Most people should not have to change this too much.
#   Should you need customization for development reasons, 
#     see the Customization section of this Dockerfile near the bottom of the file.

# declare parent image
# start from ubuntu 18.04 base docker image (specified by Docker hub itself)
FROM ubuntu:18.04

# specify working directory inside the new docker container, creating it, if does not exist
WORKDIR /cs165

# NOTE: This Run Statement is Staff Only for Setup. Students should not modify this part.
#   We keep these commands together for "caching" within docker layers.
# What are all these dependencies?
#   build-essential is needed for Make
#   gcc is needed for compilation of C
#   sse4.2-support for SIMD support
#   psmisc convenience utilities for managing processes (e.g. killall processes by name)
#   valgrind for memory issue debugging
#   tmux for multiplexing between multiple windows within your interactive docker shell
#   python 2.7.x
#   strace for stack profiling & debugging
#   mutt for email formatting, this is required on our staff automated tests
#       emailing you summaries when your trial runs are done
RUN bash -c 'apt-get update && apt-get install -y \

#   python stat packages: scipy, pandas. dependencies for test generation
RUN bash -c 'pip install scipy pandas'

#   linux tools are for utilities such as `perf` for counters / performance measurement
# enable linux-tools once MacOS linuxkit instruction support is patched and released
RUN bash -c 'apt-get install -y linux-tools-common linux-tools-generic && \
    # symlink proper linux tools to the perf shortcut \
    cd /usr/lib/linux-tools && \
    cd `ls -1 | head -n1` && \
    rm -f /usr/bin/perf && \
    ln -s `pwd`/perf /usr/bin/perf'
