Hi @shivani_aggarwal

Ok I did a quick test I used CentoOS 7, the jdk you specified and the 7.17.3 oss logstash tar.gz not the rpm.... but it looks good... see below.

I suspect their is perhaps a different issue I see here like your LS\_JAVA\_HOME is not pointed correctly or perhaps [this](https://discuss.elastic.co/t/logstash-setting-ls-java-home/307538/5) or this

`23:20:50 chmod: cannot access '/etc/default/logstash': No such file or directory `

Perhaps @Badger might have an Idea.. I am not much of a dockerfile guru for logstash I also see [this](https://discuss.elastic.co/t/logstash-setting-ls-java-home/307538/5)
