elasticsearchHow can I check if an index exists in Elasticsearch?
You can check if an index exists in Elasticsearch using the _cat/indices
API. For example, the following command will check if the index myindex
exists:
curl -XGET 'localhost:9200/_cat/indices?v&s=index'
The output will be similar to this:
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
yellow open myindex d3E3Ks7qQ0yYhgT0LsV7VQ 5 1 0 0 3.3kb 3.3kb
The parts of the command are:
curl
: the command-line tool to make HTTP requests-XGET
: the HTTP method to use for the requestlocalhost:9200
: the URL of the Elasticsearch instance_cat/indices?v&s=index
: the API endpoint to check indices
If the index exists, it will appear in the output.
