Logstash not producing output although pipeline main starts - elasticsearch

Question

I'm trying to add logs of apache using kibana elasticsearch and logstash. but logstash didn't create index to elastticsearch , so I'm not able to visualize data in kibana
this is my docker-compose :
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4
container_name: elasticsearch
hostname: elasticsearch
environment:
- cluster.name=docker-cluster
- bootstrap.memory_lock=true
- ES_JAVA_OPTS=-Xms512m -Xmx512m
- http.cors.enabled=true
- http.cors.allow-origin= "*"
ulimits:
memlock:
soft: -1
hard: -1
volumes:
- esdata1:/usr/share/elasticsearch/data
ports:
- 9200:9200
logstash:
image: docker.elastic.co/logstash/logstash-oss:6.2.4
restart: unless-stopped
depends_on:
- elasticsearch
volumes:
- ./logstash-apache.conf:/opt/logstash/logstash-apache.conf
- ./logs:/logs/access_log
links:
- elasticsearch
command: logstash -f /opt/logstash/logstash-apache.conf
kibana:
image: docker.elastic.co/kibana/kibana-oss:6.2.4
container_name: kibana
volumes:
- esdata2:/usr/share/kibana/config/data
ports:
- 5601:5601
depends_on:
- elasticsearch
links:
- elasticsearch
volumes:
esdata1:
driver: local
esdata2:
driver: local
this my Logstash-apache.conf
input {
file {
type => "apache_access"
path => "/var/log/httpd/access_log"
start_position => beginning
}
}
filter {
if [type] == "apache_access" {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}( \*\*%{POSINT:responsetime}\*\*)?" }
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
}
output {
elasticsearch {
hosts => ["elasticsearch:9200"]
index => "apache_logstash-%{+YYYY.MM.dd}"
}
}
This the output mesg:
logstash_1| [2018-07-18T23:55:25,926][INFO ][logstash.agent] Pipelines running {:count=>1, :pipelines=>["main"]}
I have no error in my output but the problem that logstash not producing data
what I shall do ? could any one help me please ?
