**Elasticsearch version** : 7.2.0  
Installed by eck-operator: 0.9.0-rc7

**Plugins installed** : as installed by eck-operator version 0.9.0-rc7  
[docker.elastic.co/elasticsearch/elasticsearch:7.2.0](http://docker.elastic.co/elasticsearch/elasticsearch:7.2.0)

**JVM version** ( `java -version` ): as used in elasticsearch docker image

**OS version** ( `uname -a` if on a Unix-like system): Host OS: Ubuntu 16.04,  
Linux 4.15.0-55-generic

**Description of the problem including expected versus actual behavior** :  
The following options are used for deploying metricbeat helm chart - overwritten values below.

ILM reports the following error:  
illegal\_argument\_exception: index.lifecycle.rollover\_alias [metricbeat] does not point to index [metricbeat-nfs-provisioner-2019.08.09]

**Steps to reproduce** :

1. install elasticsearch 7.2.0 using eck-operator at elasticsearch namespace.  
Default install with 2 nodes.

2. install metricbeat using helm chart: stable/metricbeat with the following overwrite myvalues.yml:  
helm install -f myvalues.yml --name metric --namespace elasticsearch stable/metricbeat

myvalues.yml - \> rename txt to yml  
[myvalues.txt](https://github.com/elastic/elasticsearch/files/3492626/myvalues.txt)

1. Wait 2-5min to see error on kibana. It is not seen immediately.

I read [https://www.elastic.co/guide/en/beats/metricbeat/current/ilm.html](https://www.elastic.co/guide/en/beats/metricbeat/current/ilm.html) documentation and try to put setup.ilm.pattern: "{[kubernetes.pod.\_module.namespace]}-{now/d}-01"  
but error is appeared: kubernetes.pod.\_module.namespace cannot be mapped to date format.

Goal is to create separate indices per namespace and control them via ILM policy.

Thank you! Slawek Wieczorkowski
