Prepare clean VM

Community Support

Hello!

The goal is to remove unnecessary files after creating a VM.
E.g. /etc/one-contex.d/* with all files in this directory and /tmp/one-context-tmp
I’ve tried using self-deleting scripts & directories with bash scripting.

For example:
(script file via context)

#!/bin/bash

one_dir=/etc/one-context.d
currentscript=$0
currentdir=$PWD


rpm -e one-context-4.10.0-1.noarch
rm -rf $one_dir

export currentdir

function finish {
    echo "shredding ${currentscript}"
    shred -u ${currentscript};
 
    if [ "$(ls -A ${currentdir})" ]; then
       echo "${currentdir} is not empty!"
    else
        echo "${currentdir} is empty, removing!"
        rmdir ${currentdir};
    fi

}

trap finish EXIT

echo "exiting script"

Also i try to remove with $0 each script, but there are problem with stat, because such of them run later then another, and

How i can safetly delete this files after instantiate VM?

Yes, of course!
As default I use contextualization script init.sh with some changes.
