I have implemented elastic search curator and i have installed on my node1 for implementations.I am specifying ip and port of elastic search since local host is not reachable.
The following is the command for curator i am running to take backup of entire cluster with all indices.
curator --host 10.0.20.2 --port 9200 --logfile /tmp/curator_snapshot.log --loglevel WARN --master-only snapshot --repository es_new indices --all-indices
so here i installed curator on node1 only.
- Do i need to install curator on each node? If no need to install curator on each node, what is the process of curator will it pickup master by default and perform snapshot operation?
Let say i am specifying master node ip it could be fine with out specifying --master-only parameter
I read in curator docs about --master-only feature tell cluster to create snapshot from master node only.
let say the ip specified in curator is not master node ip but i am giving create snapshot from master only using (--master-only). in this case what is the approach of curator?
please help me out to understand curator.
Thanks & Regards,
