I am using this library in go https://pkg.go.dev/github.com/elastic/go-elasticsearch/esapi#CatIndicesRequest to query from Elasticsearch.
I has some examples on querying but I am looking for a API method to get all index from Elasticsearch cluster. But I can't find one I can use from their doc. Does anyone know what the best way to get all index? like the http api _cat/indices

Here's a working example:
package main
import (
"context"
"fmt"
"github.com/elastic/go-elasticsearch/v7"
"github.com/elastic/go-elasticsearch/v7/esapi"
)
func main() {
cfg := elasticsearch.Config{
Addresses: []string{
"http://localhost:9243",
},
Username: "foo",
Password: "bar",
}
es, err := elasticsearch.NewClient(cfg)
if err != nil {
panic(err)
}
res, err := esapi.CatIndicesRequest{Format: "json"}.Do(context.Background(), es)
if err != nil {
return
}
defer res.Body.Close()
fmt.Println(res.String())
}
You can tweak the CatIndicesRequest
to format the output for your case.
For example, if you use CatIndicesRequest{Pretty: true, Human: true}
. It will return something like this:
