Hello. At 7.4.2 kibana i was able to get hosts config value from clusterClient:

```auto
const hosts = server.plugins.elasticsearch.getCluster('data').clusterClient.config.hosts

```

But now at 7.6+ it's seems imposibble because [https://github.com/elastic/kibana/pull/53824](https://github.com/elastic/kibana/pull/53824).

I also tried some solutions from here [Unknown key 'elasticsearch.hosts' for Kibana plugin config](https://discuss.elastic.co/t/unknown-key-elasticsearch-hosts-for-kibana-plugin-config/211254). But it didn't work for me.

Is there any possible solutions to get values from kibana.yml?

You can gain access to kibana.yml variables with `server.config().get()`. Then in your plugin registration, you can pass any kibana.yml variables to the client with `injectDefaultVars`.

For example

It is not working:

```auto
injectDefaultVars(server) {
  const config = server.config();
  return {
    testHosts: config.get('elasticsearch.hosts'),
  };
},

```

```auto

You will need to register your new kibana.yml configuration options in joi schema

Yes. But error raise when web page loads for the first time (in my case getting `http://localhost:5603/dev/`), not when getting a value from config object.

```auto
      ...
      injectDefaultVars(server) {
        const config = server.config();
        return {
          testHosts: config.get('elasticsearch.hosts'),
        };
      },
    },

    config(Joi) {
      return Joi.object({
        enabled: Joi.boolean().default(true),
        testHosts: Joi.string().default('no hosts')
      }).default();
    },

```

Error when running yarn start:

That is interesting. It looks like you can not grab kibana.yml configurations from another plugin.

If you take a look at sense plugin, dev tools, then you can see where it grabs elasticsearchUrl contains elasticsearch.hosts.

```auto
ReferenceError: first is not defined

It seems like it's not working on 7.6.1. Btw i looked at 7.6.1 source code of console plugin ([https://github.com/elastic/kibana/blob/v7.6.1/src/legacy/core\_plugins/console/index.ts](https://github.com/elastic/kibana/blob/v7.6.1/src/legacy/core_plugins/console/index.ts)). Here is too much hack code. So I'm thinking about reading and parsing kibana.yml myself.

Also i see that there is a "newPlatform" for plugins. Found some plugins at [https://github.com/elastic/kibana/tree/v7.6.1/src/plugins](https://github.com/elastic/kibana/tree/v7.6.1/src/plugins). But I didn't find any public documentation for developing plugins on the "newPlatform". Are any available? Also kbn-plugin-generator still generates "legacy" plugins in v7.6.1 branch (did not checked v7.6.2).

Thanks for helping

upd. I found migration guide: [https://github.com/elastic/kibana/blob/master/src/core/MIGRATION.md](https://github.com/elastic/kibana/blob/master/src/core/MIGRATION.md)
