Logstash output is from another input - kubernetes

Question

I have an issue where my beatmetric is caught by my http pipeline.
Both Logstash, Elastic and Metricbeat is running in Kubernetes.
My beatmetric is setup to send to Logstash on port 5044 and log to a file in /tmp. This works fine. But whenever I create a pipeline with an http input, this seems to also catch beatmetric inputs and send them to index2 in Elastic as defined in the http pipeline.
Why does it behave like this?
/usr/share/logstash/pipeline/http.conf
input {
http {
port => "8080"
}
}
output {
#stdout { codec => rubydebug }
elasticsearch {
hosts => ["http://my-host.com:9200"]
index => "test2"
}
}
/usr/share/logstash/pipeline/beats.conf
input {
beats {
port => "5044"
}
}
output {
file {
path => '/tmp/beats.log'
codec => "json"
}
}
/usr/share/logstash/config/logstash.yml
pipeline.id: main
pipeline.workers: 1
pipeline.batch.size: 125
pipeline.batch.delay: 50
http.host: "0.0.0.0"
http.port: 9600
config.reload.automatic: true
config.reload.interval: 3s
/usr/share/logstash/config/pipeline.yml
- pipeline.id: main
path.config: "/usr/share/logstash/pipeline"

Even if you have multiple config files, they are read as a single pipeline by logstash, concatenating the inputs, filters and outputs, if you need to run then as separate pipelines you have two options.
Change your pipelines.yml and create differents pipeline.id, each one pointing to one of the config files.
- pipeline.id: beats
path.config: "/usr/share/logstash/pipeline/beats.conf"
- pipeline.id: http
path.config: "/usr/share/logstash/pipeline/http.conf"
Or you can use tags in your input, filter and output, for example:
input {
http {
port => "8080"
tags => ["http"]
}
beats {
port => "5044"
tags => ["beats"]
}
}
output {
if "http" in [tags] {
elasticsearch {
hosts => ["http://my-host.com:9200"]
index => "test2"
}
}
if "beats" in [tags] {
file {
path => '/tmp/beats.log'
codec => "json"
}
}
}
Using the pipelines.yml file is the recommended way to running multiple pipelines
