Hi , I'm using Logstash with docker to send apache logs to elasticsearch , when I use beats plugin as input it's works fine , but when I try file input plugin , nothing happens , there is no indices in elasticsearch , this is my config file 
input
{
file {
path => "/var/log/apache/apache_logs.log"
start_position => "beginning"
ignore_older => 0
sincedb_path => "/dev/null"
}
}
filter
{
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
output
{
elasticsearch {
index => "apache-logs"
hosts => {"localhost:9200"}
stdout {
codec => rubydebug
}
}
