Hi all I am deploy logstash consumer on kubernetes with following specification:
Logstash version logstash:6.6.1
I am picking up all the values from the environment variable, my config file looks like this:
input {
kafka {
type =\> nginxlogs
bootstrap\_servers =\> ["{KAFKA\_BROKERS}"] group\_id =\> "{NGINXLOGS\_CONSUMER\_GROUP\_ID}"
topics\_pattern =\> ["{NGINXLOGS\_KAFKA\_TOPIC\_PATTERN}"] consumer\_threads =\> "{NGINXLOGS\_CONSUMER\_THREADS}"
metadata\_max\_age\_ms =\> "5000"
partition\_assignment\_strategy =\> "org.apache.kafka.clients.consumer.RoundRobinAssignor"
codec =\> "json"
add\_field =\> {
"broker" =\> "input\_from\_nginxlogs\_topic"
}
}
kafka {
type =\> applicationlogs
bootstrap\_servers =\> ["{KAFKA\_BROKERS}"] group\_id =\> "{APPLICATIONLOGS\_CONSUMER\_GROUP\_ID}"
topics\_pattern =\> ["{APPLICATIONLOGS\_KAFKA\_TOPIC\_PATTERN}"] consumer\_threads =\> "{APPLICATIONLOGS\_CONSUMER\_THREADS}"
metadata\_max\_age\_ms =\> "5000"
partition\_assignment\_strategy =\> "org.apache.kafka.clients.consumer.RoundRobinAssignor"
codec =\> "json"
add\_field =\> {
"broker" =\> "input\_from\_applicationlogs\_topic"
}
}
kafka {
type =\> containerconsolelogs
bootstrap\_servers =\> ["{KAFKA\_BROKERS}"] group\_id =\> "{CONTAINERCONSOLELOGS\_CONSUMER\_GROUP\_ID}"
topics\_pattern =\> ["{CONTAINERCONSOLELOGS\_KAFKA\_TOPIC\_PATTERN}"] consumer\_threads =\> "{CONTAINERCONSOLELOGS\_CONSUMER\_THREADS}"
metadata\_max\_age\_ms =\> "5000"
partition\_assignment\_strategy =\> "org.apache.kafka.clients.consumer.RoundRobinAssignor"
codec =\> "json"
add\_field =\> {
"broker" =\> "input\_from\_containerconsolelogs\_topic"
}
}
}
output {
if [type] == "nginxlogs"{
elasticsearch {
hosts =\> "{ELASTICSEARCH\_HOSTS}" index =\> '"{NGINXLOGS\_KAFKA\_TOPIC\_PATTERN}"-%{+YYYY.MM}'
}
}
else if [type] == "applicationlogs"{
elasticsearch {
hosts =\> "{ELASTICSEARCH\_HOSTS}" index =\> '"{APPLICATIONLOGS\_KAFKA\_TOPIC\_PATTERN}"-%{+YYYY.MM}'
}
}
else if [type] == "containerconsolelogs"{
elasticsearch {
hosts =\> "{ELASTICSEARCH\_HOSTS}" index =\> '"{CONTAINERCONSOLELOGS\_KAFKA\_TOPIC\_PATTERN}"-%{+YYYY.MM}'
}
}
else {
null { }
}
}
Issue I am facing is When I hardcode the same elasticsearch values in the file it works, but when I pass the same values in the environment variable it throughs error saying:
[2019-02-27T11:21:56,791][FATAL][logstash.runner] The given configuration is invalid. Reason: Illegal character in scheme name at index 0: ["172.23.130.220:9200","172.23.130.164:9200","172.23.130.116:9200","172.23.130.109:9200"]
I tried all possible permutation and combination didn't get anything.
Environment variables for reference:
export NGINXLOGS\_KAFKA\_TOPIC\_PATTERN="nginxlogs"
export NGINXLOGS\_CONSUMER\_GROUP\_ID="nginxlogs"
export NGINXLOGS\_CONSUMER\_THREADS="5"
export APPLICATIONLOGS\_KAFKA\_TOPIC\_PATTERN="applicationlogs"
export APPLICATIONLOGS\_CONSUMER\_GROUP\_ID="applicationlogs"
export APPLICATIONLOGS\_CONSUMER\_THREADS="3"
export CONTAINERCONSOLELOGS\_KAFKA\_TOPIC\_PATTERN="containerconsolelogs"
export CONTAINERCONSOLELOGS\_CONSUMER\_GROUP\_ID="containerconsolelogs"
export CONTAINERCONSOLELOGS\_CONSUMER\_THREADS="5"
export BATCH\_DELAY="5"
export BATCH\_SIZE="200"
export KAFKA\_BROKERS=[a0a5398d9e8d-808076471.eu-west-1.elb.amazonaws.com:9092](http://a0a5398d9e8d-808076471.eu-west-1.elb.amazonaws.com:9092),

The code that processes hosts expects to receive either a string containing a single host, or an array containing mulitple hosts. When you do that variable substitution it gets passed a string containing multiple hosts, and that does not work.
If you have a fixed number of hosts you can use
```
hosts => ["${ELASTICSEARCH_HOST1}", "${ELASTICSEARCH_HOST2}", "${ELASTICSEARCH_HOST3}", "${ELASTICSEARCH_HOST4}"]
```

Is there any way to use an environment variable substitution with an unknown number of hosts? I've tried various ways of adding multiple host values to a single environment variable but logstash doesn't seem to like any of them.

I cannot think of any way to do it.
