Plugin repository-gcs not working for snapshots

I’m trying to create a snapshot and storing in our google cloud storage for some time with no success. I found this task very hard since there is no documentation. I’m trying to use some of elastic, opeansearch and S3 configuration to make it work.

I’ve already installed repository-gcs and created a registry on keystore like this:

bin/opensearch-keystore add-file gcs.client.some_client.credentials_file google_app_credentials.json

the google_app_credentials.json was generated in GCP following the documentation below

Now I’m trying to configure the repository

curl -X PUT http://localhost:9200/_snapshot/some_repository -H "Content-Type: application/json" -d 
'{
   "type": "gcs", 
   "settings": {
      "bucket": "bucket_name_on_gcp", 
      "base_path": "usr/share/opensearch/repository", 
      "client": "some_client"
     }
   }'

but I’m getting this error:

{
   "error": {
      "root_cause": [
         {
            "type": "repository_verification_exception","reason":"[some_repository] path [usr][share][opensearch][repository] is not accessible on cluster-manager node"
         }
      ],
      "type":"repository_verification_exception",
      "reason":"[thiago_repository] path [usr][share][opensearch][repository] is not accessible on cluster-manager node",
      "caused_by": {
            "type":"access_control_exception",
            "reason":"access denied (\"java.io.FilePermission\" \"/usr/share/opensearch/.config/gcloud/active_config\" \"read\")"
            }
      },
      "status":500
}

someone can help?

Mabe using absolte path instead of relative?. I will try locally and confirm with you.

Are you able to make snapshots work with Google Storage? I’d like to do the same thing. Thanks.

did you succeded doing with the full path?
