Subject: [PATCH] optimize apt-get step (#18)

source: https://www.fromlatest.io/#/

Line 8: Consider `--no-install-recommends` (Optimization)
Consider using a --no-install-recommends when apt-get installing packages. This will result in a smaller image size.

Line 8: apt-get update with matching cache rm (Optimization)
Use of apt-get update should be paired with rm -rf /var/lib/apt/lists/* in the same layer.
