[PATCH] Docker: Remove libsdl and xterm

[Jan Kiszka]

From: Jan Kiszka <jan.k...@siemens.com>

These packages date back from the (pre-public) times when the list was
also used for developer host setups.

Suggested-by: Mustafa Yuecel <mustafa...@siemens.com>

Applies on top of the Debian switch, I didn't try Ubuntu anymore.

Installed size reduction: ~130 MB
The (offlist) suggested apt-get clean & Co. didn't provide reductions.
Seems like something is doing this automatically.

apt-get clean & Co must be specified on each apt-get update/install run, otherwise you will not see any reduction. Once files are stored in a layer you will not get it away afterwards, somehow like git ;)

RUN apt-get update && \
apt-get install -y locales && \

sed -i -e "s/# $LOCALE.*/$LOCALE UTF-8/" /etc/locale.gen && \
dpkg-reconfigure --frontend=noninteractive locales && \
apt-get clean && \
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

RUN apt-get update && \
apt-get -y install gawk ... lsb-release && \
apt-get clean && \
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

This way you will save ~35MB...

Good to know, indeed!

I managed to save 12 MB by combining both steps and adding your cleanup
rules at the end. With separate steps like above, I only saved 10 MB.
Maybe you tried with Ubuntu or without the removal patch below?

Anyway, another cleanup patch on top will follow, thanks!

I tried it on Ubuntu where more repositories seems to be available
