Instead of running multiple instances I would recommend you to add few lines of code in your tool configuration file (.xml)
1. Export the $__user_email__ variable along with the tool call section in XML file.
ex:
<command>/path-to-tool/wrapper.sh ARG1 ARG2 ... $__user_email__
</command>
2. In the wrapper.sh script, add the following line in the before calling your main program.
if [ "${@: -1}" != "
vipin.ts@gmail.com" ];
then
echo 'You donot have enough privilege to access this tool, please contact
galaxy@tuebingen.mpg.de'
exit
fi
By doing this way the tool name will be listed in the tool panel of Galaxy instance, but for this specified
user can only access the same. I know this is not an automated way of implementation and happy to hear
if somebody have another fix for the same.
I implemented this in my public Galaxy instance and it is accessible
here.
HTH, Vipin
