How to get logs[data] generated by running application using Logstash Container - logstash

Question

I am new to logstash and docker.
I am using logstash container to retrieve logs, generated by other application. As i am able to run container successful but i am not getting the output in my file "finalOuput.log" [ both the file finalOuput.log & pipeline.conf is in container]
1->
My Docker File Content:
FROM logstash
copy pipeline.conf /var/app/
copy finalOuput.log /var/app/
CMD ["-f", "/var/app/pipeline.conf"]
2-> My pipeline.config file contains
input {
file {
path => "/predix/Documents/workspace-sts-3.8.1.RELEASE/sendRohit/9aug/application-logs/application-log.log"
}
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}"}
}
}
output {
file {
path => "/finalOuput.log"
codec => line { format => "custom format: %{message}"}
}
}

Answer 1

Now i am getting the data. Need to put the pipeline.conf in the root directory of container.
FROM logstash
run mkdir rvol
copy third-pipeline.conf /
copy outputdata.log /rvol/
copy inputData.log /rvol/
CMD ["-f", "/third-pipeline.conf"]
And then fire the command: Below command is single command
docker run -d --name=container_Name -v '/predix/Documents/rvol/inputData.log':'/rvol/inputData.log' -v '/predix/Documents/rvol/outputdata.log':'/rvol/outputdata.log' image_Name
