installazione di `lightdm` in Dockerfile solleva tastiera interattiva menu Layout

Question

Ho la seguente Dockerfile:

# Pull from CentOS RPM Build Image 
FROM ubuntu 

# Update the image 
RUN apt-get update -y 
RUN apt-get install lightdm -y 

Il problema che ho è quando sto costruendo questo contenitore con docker build -t dumbcontainer ., ad un certo punto ho ottenere un menu interattivo per la scelta di un layout di tastiera:

The layout of keyboards varies per country, with some countries having multiple 
common layouts. Please select the country of origin for the keyboard of this 
computer. 

    1. Afghani          48. Irish 
    2. Albanian         49. Italian 
    3. Amharic          50. Japanese

ho Prova a mettere un'opzione, ma il processo appena bancarelle a quel punto

c'è un modo che io ca n scegliere un'opzione in modo interattivo o fare in modo che la finestra mobile passi un'opzione quando viene richiesto di farlo?

Answer 1

provare a impostare una variabile di ambiente TERM prima di eseguire l'installazione: ENV TERM xterm al fine di sbarazzarsi di tale errore, anche se non sono sicuro di come si dovrebbe specificare l'opzione della tastiera.

Answer 2

1. copia di un lavoro/etc/default/file della tastiera per la directory che contiene il Dockerfile

2. Aggiungere la seguente riga al Dockerfile prima di installare o xdm lightdm

   COPIA ./keyboard/etc/default/keyboard file di tastiera

Esempio:

# Check /usr/share/doc/keyboard-configuration/README.Debian for 
# documentation on what to do after having modified this file. 

# The following variables describe your keyboard and can have the same 
# values as the XkbModel, XkbLayout, XkbVariant and XkbOptions options 
# in /etc/X11/xorg.conf. 

XKBMODEL="pc105" 
XKBLAYOUT="us" 
XKBVARIANT="intl" 
XKBOPTIONS="" 

# If you don't want to use the XKB layout on the console, you can 
# specify an alternative keymap. Make sure it will be accessible 
# before /usr is mounted. 
# KMAP=/etc/console-setup/defkeymap.kmap.gz 
BACKSPACE="guess" 

Answer 3

questo dovrebbe funzionare:

DEBIAN_FRONTEND=noninteractive apt-get install lightdm -y 

Ho avuto lo stesso problema l'installazione di CUDA e questo riparato.
