Is it possible to prefix PS1 for bash?

[juxeii]

Hi,

I am using a theme in bash.
I've written a little docker container, in which the users should get it normal PS1 prompt, but now prefixed with some string, to indicate to him that he is working in the container.

Example:
Normal prompt would be:
foobar:>
In container it should become prefixed
(coolapp)foobar:>

How can I hook into the mechanics of oh-my-posh to achieve this?

Nevermind, here is what works for me

#!/bin/bash

update_ps1() {
    PS1="\[\e[38;5;2m\](coolapp)\e[m$PS1"
}

# source the user's bashrc
source ~/.bashrc

# adapt prompt
PROMPT_COMMAND="$PROMPT_COMMAND update_ps1"
