A common technique is to call apt-get purge -y --auto-remove ... in one
step.
It is often seen with a temporary variable like this:
RUN buildDeps=" \
flex \
... \
"; \
&& apt-get install -y --no-install-recommends $buildDeps
&& ...build and other cleanups
&& apt-get purge -y $buildDeps
@JensG We also need to install Go to use `-gen go` (because it uses
`gofmt`), right ?
