I am trying to achieve conditional indexing for namespaces in elastic using ingest node pipelines. I used the below pipeline but the index getting created when I add the pipeline in metricbeat.yml is in form of datastreams.
```auto
PUT _ingest/pipeline/sample-pipeline
{
"processors": [
{
"set": {
"field": "_index",
"copy_from": "metricbeat-dev",
"if": "ctx.kubernetes?.namespace==\"dev\"",
"ignore_failure": true
}
}
]
}
```
Expected index name is metricbeat-dev but i am getting the value in \_index as .ds-metricbeat-dev. This works fine when I test with one document but when I implement it in yml file I get the index name starting with .ds- why is this happening?
