# Pod update strategy for Logstash on ECK
The operator takes a Pod down to restart and applies a new configuration value. All Pods are restarted in reverse ordinal order.

## Default behavior

When `updateStrategy` is not present in the specification, it defaults to the following:
```yaml
spec:
  updateStrategy:
    type: "RollingUpdate" 
    rollingUpdate:
      partition: 0        
      maxUnavailable: 1   
```


## OnDelete

```yaml
spec:
  updateStrategy:
    type: "OnDelete"
```

`OnDelete` strategy does not automatically update Pods when a modification is made. You need to restart Pods yourself.
