Modify replica counts on an existing installation¶

You can use the helm upgrade command to modify replica counts across non-RethinkDB MSR resources. For the RethinkDB resources, refer to Modify replica counts for RethinkDB resources.

To modify replica counts for MSR resources:

In the ha.yaml file, edit the key-value pair that corresponds to the MSR resource whose replica count you wish to modify. For example, nginx:

Note

Refer to The ha.yaml file sample for the full configuration example.
```
nginx:
  replicaCount: <desired-replica-count>
```

To apply the new values, run helm upgrade:

helm upgrade msrofficial/msr –-version 1.0.0 -f ha.yaml
