Getting the official Logstash Docker container running on CentOS 7. Strange error after 15 or 30 seconds of launching the instance:

> Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties  
> 21:32:34.666 [LogStash::Runner] ERROR logstash.agent - fetched an invalid config {:config=\>"input {\n syslog {}\n tcp {\n port =\> 1514\n type =\> syslog\n }\n udp {\n port =\> 1514\n type =\> syslog\n }\n gelf {}\n}\noutput {\n redis {\n host =\> "logging-redis"\n data\_type =\> "list"\n key =\> "logstash:redis"\n }\n}\n\n", :reason=\>"Expected one of #, if, ", ', } at line 2, column 1 (byte 9) after input {\n"}  
> 2017-02-09 21:32:34,722 Api Webserver ERROR No log4j2 configuration file found. Using default configuration: logging only errors to the console.

My logstash.conf just looks like this (as referenced in the error above):  
input {  
syslog {}  
tcp {  
port =\> 1514  
type =\> syslog  
}  
udp {  
port =\> 1514  
type =\> syslog  
}  
gelf {}  
}  
output {  
redis {  
host =\> "logging-redis"  
data\_type =\> "list"  
key =\> "logstash:redis"  
}  
}

I don't understand what's going on. I'm not even using "log4j2."

Never mind log4j2, that's noise. There's something on or near line 2 that Logstash doesn't like. Do you have an invisible garbage character right before "syslog{}" or thereabouts? You can inspect the file with e.g. `hexdump -C`.

See those sequences of `c2 a0` everywhere? They're non-breaking spaces and they don't belong in your configuration file. Use regular spaces.
