this is what happens :

root@Z390-AORUS-PRO:/home/ziomario/Scrivania/Virt/dockers/ziomario-docker# ./run.sh

Hello, whats your user name ?mario

mario

No qcow2 Filesystem detected at /home/mario/budgieVM.qcow2!

No zipped Filesystem detected at /home/mario/budgieVM.zip!


you knoow why ? I imagine that the reason is because the value of $username is empty.


VOLUME /home/$username

COPY start.sh /start.sh

ENTRYPOINT \["/start.sh"\]

it's the same if I do :

VOLUME /home

COPY start.sh /start.sh

ENTRYPOINT \["/start.sh"\]

because it copies the file on /home,but I want it on /home/$username


let's recap. this is how is configured everything :


Dockerfile


RUN chmod +x /usr/local/bin/firefox && \
    echo "$username:x:1000:1000:Usernames,,,:/home/$username:/bin/bash" >> /etc/passwd && \
    echo "$username:x:1000:" >> /etc/group && \
    echo "$username ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d && \
    chmod 0440 /etc/sudoers.d && \
    chown $username:$username -R /home/$username

ARG FILESYSTEM_IMAGE_URL="http://ziomario.ns0.it/budgieVM.zip"
ADD $FILESYSTEM_IMAGE_URL /home/$username/budgieVM.zip

VOLUME /home

COPY start.sh /start.sh
ENTRYPOINT ["/start.sh"]


start.sh


/bin/bash

#rm hostusername 2> /dev/null
hostusername=$(whoami)
echo $hostusername
#echo "$hostusername" > "hostusername"

#rm username 2> /dev/null
echo -n " Hello, whats your username ?"
read -r
username=$REPLY
echo $username
#echo "$username" > "username"

mkdir -p /home/$username

image_path="/home/$username/budgieVM.qcow2"
zip_path="/home/$username/budgieVM.zip"

if [ ! -e $image_path ]; then
  echo "No qcow2 Filesystem detected at ${image_path}!"
  if [ -e $zip_path ]; then
      echo "Extracting fresh filesystem..."
      unzip $zip_path
      mv -- *.img $image_path
  else
    echo "No zipped Filesystem detected at ${zip_path}!"
    exit 1
  fi
fi
      echo "Extracting fresh filesystem..."

      #!/bin/bash
