Need to know

• Build by your own image: because this image only has few pre-installed programs. If you want to execute others in the container, you might want to build your own, e.q.

  FROM sstc/kala:all
  RUN set -ex; \
    apt-get update; \
    DEBIAN_FRONTEND=noninteractive apt-get install --no-install-recommends -y \
    julia \
    ; \
    apt-get clean; \
    rm -rf /var/lib/apt/lists/*

  docker build -t kala .
  docker run --rm kala julia -e 'println("hello world")'
