Docker Bash Has No Colour

Question

When I run

docker run -i -t python /bin/bash

the resulting terminal has no color.

I've looked at the following links and they haven't helped:

Docker bash prompt not display color

I'm using the Docker Quickstart Terminal from the Docker Toolbox on Windows 10. I have docker version 1.12.0, build 8eab29e.

To fix this you need to update the ~/.bashrc file.

Adding something like this (borrowed from the default Ubuntu ~/.bashrc file) should do the trick:

if [ -x /usr/bin/dircolors ]; then
test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
alias ls='ls --color=auto'
alias grep='grep --color=auto'
alias fgrep='fgrep --color=auto'
alias egrep='egrep --color=auto'
fi

Once you've updated the ~/.bash file, you need to reload the file by running source ~/.bashrc .

You may want to create your own dockerfile which does this automatically.
