hello,
Mine is a single node set up , and hence no replicas are assigned (i think ?) . Is it possible to set default replica number as 0 in elasticsearch.yml ?
```auto
GET /_cat/allocation?v
shards disk.indices disk.used disk.avail disk.total disk.percent host ip node
29 6.9gb 10.2gb 38.7gb 48.9gb 20 nexus-dev01.test.com 172.26.207.164 Nexus-dev01
13 UNASSIGNED
```
The reason seems to be this
```auto
GET _cat/shards?h=index,shard,prirep,state,unassigned.reason
.kibana_7.13.2_001 0 p STARTED
logstash-ghostmon-000009 0 p STARTED
logstash-ghostmon-000009 0 r UNASSIGNED INDEX_CREATED
.async-search 0 p STARTED
.apm-agent-configuration 0 p STARTED
.security-7 0 p STARTED
.kibana-event-log-7.13.2-000002 0 p STARTED
logstash-ghostmon-000008 0 p STARTED
logstash-ghostmon-000008 0 r UNASSIGNED INDEX_CREATED
logstash_viz1 0 p STARTED
logstash_viz1 0 r UNASSIGNED CLUSTER_RECOVERED
logstash-ghostmon-000006 0 p STARTED
logstash-ghostmon-000006 0 r UNASSIGNED INDEX_CREATED
```

I haven't run into this problem in quite a while but I also haven't played with a single node in quite a while either.
I think you should set your discovery type to single node.
`discovery.type: single-node # configure as single-node cluster`
If you're still having problems you can use an index template and set it to apply to \* (all indices)
you can do that in kibana under management or do this in the console
```auto
PUT _template/no-replicas
{
"index_patterns": [
"*"
],
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
}
}
```
Then any index you create will default to 1 shard and 0 zero replicas
