Every 30 seconds, the system status will be stored in the ES. The index name is, for example, i\_index-2019-10-10. The aggregation will be done every 5 minutes. The data of this table will be summarized into the 5-minute table. The index name is for example: i\_index- 5m-2019-10-10, I want to use a template definition, i\_index-20\* corresponds to the alias a\_index, and i\_index-5m-\* corresponds to the alias a\_index-5m.  
How should the template file be written?  
Elasticsearch version :7.3.1  
1.I tried to write like this, it doesn't work

```json
 PUT _template/t_ceshi
{
 "order": 0,
 "index_patterns": ["i_ceshi-*"],
 "settings": {
   "index": {
     "number_of_shards": "1",
     "number_of_replicas": "0",
     "refresh_interval": "5s"
   }
 },
 "mappings": {
   "dynamic": false,
   "properties": {
     
   }
 },
 "aliases": {
   "actions" : [
       { "add" : { "index" : "i_ceshi-20*", "alias" : "a_ceshi" } },
       { "add" : { "index" : "i_ceshi-5m-*", "alias" : "a_ceshi-5m" } }
   ]
 }
}

```

2.I also tried to write like this, it doesn’t work either.

```json
PUT _template/t_ceshi
 {
   "order": 0,
   "index_patterns": ["i_ceshi-*"],
   "settings": {
     "index": {
       "number_of_shards": "1",
       "number_of_replicas": "0",
       "refresh_interval": "5s"
     }
   },
   "mappings": {
     "dynamic": false,
     "properties": {
       
   }
   },
   "aliases": {
     "a_ceshi": {"index":"i_ceshi-20*"},
     "a_ceshi-5m": {"index":"i_ceshi-5m-*"}
   }
 }

```
