```auto

      if [fields][env] == "canary" {
        elasticsearch {
          hosts => ["elastic-cluster:9200"]
          ilm_enabled => true
          ilm_policy => "k8s-logs"
          index => "k8s-%{[kubernetes][namespace]}-%{[kubernetes][labels][app]}-%{+YYYY.MM.dd}"
          ilm_pattern => "%{+YYYY.MM.dd}"
          ilm_rollover_alias => "k8s-%{[kubernetes][namespace]}-%{[kubernetes][labels][app]}"

Do you have an alias in place that is called that?

I wish I could use the variable {{index}}.  
Such as the` index = k8s - kube - system - 2021.11.08`, rollover alias= `K8S-kube-system-2021.11.09`, The index is updated by date.

So i set logstash

```auto
ilm_pattern => "%{+YYYY.MM.dd}"
ilm_rollover_alias => "k8s-%{[kubernetes][namespace]}-%{[kubernetes][labels][app]}"

```

Set template

```auto
"rollover_alias": "{index}"

```

But it's doesn't work.Am I missing something？

That will not work, no. You need to be explicit there.

You will need to create each one manually at this point.
