Elasticsearch Keystore creation for curator snapshot

Elastic Stack Elasticsearch
1

I have multi node elastic-search cluster (1 master, 5 datanode), I need to take snapshot of indices and store in gcs bucket. As per the documentation, we need to add client service key into the elasticsearch-keystore (bin/elasticsearch-keystore add-file gcs.client.credential-file ./service-key.json)

Do we need to add this keystore into elastic keystore for all the master and datanode?
I added the keystore in one datanode and tried to take snapshot, but it throwing error.
Please advice do we need to add this key in all the elastic nodes?

Yes, you need to add an entry to the keystore on each node
