# These are always installed. Notes:
#   * dumb-init: a proper init system for containers, to reap zombie children
#   * bash: For entrypoint, and debugging
#   * ca-certificates: for SSL verification during Pip and easy_install
#   * python: the binaries themselves
#   * openblas: required for numpy.
#   * libaio libnsl: for cx_Oracle

# These packages are not installed immediately, but are added at runtime or ONBUILD to shrink the image as much as possible. Notes:
#   * build-base: used so we include the basic development packages (GCc)
#   * linux-headers: commonly needed, and an unusual package name from Alpine.
