I am trying to create a new ActionPlugin. On ES starting, I want to create a NodeClient and do some work with it. How can I do that?

Do you really want to do that when your node is starting, or when it has joined a cluster and the node is ready to serve requests? There are some listeners that sound like a better way.

The `Plugin.createComponents` method passes a `Client` that you can use, there is no need to create your own.

I need to do that when it has joined a cluster and the node is ready to serve requests.  
can you provide some links to the listeners use, and the `Plugin.createComponents`?  
Thanks

The example plugins are a good place to start. See [elasticsearch/plugins/examples at 7.14 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/tree/7.14/plugins/examples)
