Hello,
I have a similar question to [this post](https://discuss.elastic.co/t/partial-update-and-nested-type-performance/110534).
I am running a single node cluster for development and I do not want indexes to be trying to allocate replicas. I have templates for my indexes, but the watcher history indexes allocate replica nodes. When I try to set the "index.number\_of\_replicas" setting in elasticsearch.yml, it is an invalid property.
The goal here is to keep my cluster status green. Is there another way to achieve this?
Thanks

Yes, you should use [index templates](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/indices-templates.html) for this, where you can do:
```auto
PUT /_template/my_template
{ "index_patterns": ["*"], "settings": { "number_of_replicas": 0 } }
```
So that all newly created indices automatically have 0 replicas.
