Hi,

I am going to use Ansible to deploy Elasticsearch and Logstash. Before deploying Logstash, I’d like to check if the health status of Elasticsearch cluster is green or not, e.g.,

$ curl -s 127.0.0.1:9200/\_cat/health?v  
epoch timestamp cluster status  
1482992016 06:13:36 elasticsearch-default green

It will take some time for Elasticsearch cluster to become healthy, so I’d like to check it in a loop until it become healthy or timeout. Is it possible to do this with Ansible? Thanks!

Regards,  
Qian
