Auto-creating indices even though configured not to

Elastic Stack Elasticsearch
1

I want to have full control over what indices are created in my cluster, so I have configured

PUT _cluster/settings
{
    "persistent": {
        "action.auto_create_index": "false" 
    }
}

Still, when using NEST to send a BulkUpdateOperation, indices are auto-created, but I expect them to return 404.

new BulkUpdateOperation<RankedDto, Dto>(
          new RankedDto { Id = dto.Id }, dto, true) 
         {Index = "something_something"}

This operation gives me a 201 with index "something_something" created, even though I would expect it to give me a 404.

Do I need to configure something else as well?

I'm using Elastic Cloud 7.6.1

Hey,

you can change that setting under your deployment in the "Edit" part and then search for Elasticsearch plugins and settings - there is a checkbox to select this.

@spinscale Ok, thanks! That seems to affect both

"persistent": {
        "action.auto_create_index": "false" 
    }

and

"transient": {
        "action.auto_create_index": "false" 
    }

so perhaps that was the answer I was looking for.

In other words: this is not enough:

PUT _cluster/settings
{
    "persistent": {
        "action.auto_create_index": "false" 
    }
}

This should be correct:

PUT _cluster/settings
{
    "persistent": {
        "action.auto_create_index": "false" 
    },
  "transient": {
        "action.auto_create_index": "false" 
    }
}

thanks!
