Arrow keys do not work for terminal emulators about docker-baseimage-gui HOT 4 CLOSED

Sorry for the delay. Alpine is working fine. If you want to stick with Debian images, you can use the SHELL variable to set the shell to be used by xterm. So for example, your startapp.sh could be:

#!/bin/sh
export SHELL=/bin/bash
exec /usr/bin/xterm

from docker-baseimage-gui.

It seems to be an issue with the terminal itself, which is not handling arrow keys properly. I tried with xterm and it works perfectly.

@jlesage Thank you for telling me that.

But It does occur to xterm and Debian 10.
It can also be reproduced using xfce4-terminal, and it occurs no matter if you connect to it through Firefox, Chromium, or TigerVNC.

Dockerfile

FROM jlesage/baseimage-gui:debian-10
COPY startapp.sh /startapp.sh
RUN \
apt-get update && \
apt-get install -y xterm
ENV APP_NAME="Testarrow"

startapp.sh

#!/bin/sh
exec /usr/bin/xterm

start.sh

#!/usr/bin/env sh
docker build -t docker-xterm .
docker run --rm -p 5800:5800 -p 5900:5900 docker-xterm

Should I try Alpine Linux instead?
