Logstash Post Install of plugins

For those who are struggeling with the install of plugins and having them install on spinning up a container I have wrote this
mount the file from your volumn outside the container
to Container Path: /usr/share/logstash/config/plugins.sh
add a post argument
sh /usr/share/logstash/config/plugins.sh
file contents

#!binbash

echo running post install scripts for plugins..;
logstash-plugin install logstash-filter-sentimentalizer
logstash-plugin install logstash-input-mysql
echo finished post install scripts for plugins..;
sleep 1
exec logstash 

the exec logstash is what kicks logstash into starting after the plugin installs.

If anyone has any input on how I can omitt the plugins.sh from running on just a basic restart of the container I would be interested in your advice.
