Retrieve role info in Elasticsearch plugin

Elastic Stack Elasticsearch
1

Hi,

I'm building a custom plugin and need to retrieve, at some point, all info about a specific role by its name.
How can I do that?
Do I need to use org.elasticsearch.client.Client, is so could you provide a sample please?

Thanks
Regards

Without more information about what type of plugin you have, and where you want to retrieve the roles, it's hard to provide a useful sample.

If you have a Client, then you can construct an instance of org.elasticsearch.xpack.core.security.client.SecurityClient and call getRoles from that.

Hi,

thank you for you answer.
It's a plugin built upon the one from this guide.
The only Elasticsearch dependencies I have are:

<dependency>
  <groupId>org.elasticsearch</groupId>
  <artifactId>elasticsearch</artifactId>
  <version>${elastic.version}</version>
  <scope>provided</scope>
</dependency>

<dependency>
  <groupId>org.elasticsearch.plugin</groupId>
  <artifactId>x-pack-core</artifactId>
  <version>${elastic.version}</version>
  <scope>provided</scope>
</dependency>

and when I'm in the buildRole() method in WebstoreRolesProvider class I want to retrieve information from the Set<String> names of roles coming from the lookup() method.

I saw the org.elasticsearch.xpack.core.security.client.SecurityClient, but I'm not sure how to build an ElasticsearchClient implementation and pass it to its constructor.
Do I need to add any specific dependency?

Thanks

edit:

I also saw that the future will be using RestHighLevelClient so is there any way to use it to retrieve roles info?

Thanks

Client implements ElasticsearchClient, so it you have a Client then you can construct a SecurityClient.

You need to get the Client as part of the Plugin.createComponents method, and then retain a reference to that client for use in your Realm.

in WebstoreRolesProvider class I want to retrieve information from the Set<String> names of roles coming from the lookup() method.

That doesn't mean sense to me. Your roles provider needs to create those roles - they will not exist in Elasticsearch. If they did exist in Elasticsearch then your roles provider would not be called.

thanks @TimV I'll try that!

oh I see. I'll review my logic then. Thanks
