Hi all,

I trying to make changes to kibana core source code and I trying to access the variables in kibana.yml file from my JS file. Example is shown as below:

```
let elastic_url = process.env['elasticsearch.hosts']

```

Would really appreciate if anyone can give some pointers.

Note: I not trying to access from plugins.

Hey @GiGiLord

Generally speaking, within the new plugin structure, variables from `kibana.yml` are accessible only on the **server side** by using the plugin context `initializerContext.config` that's passed to the server plugin constructor as the first parameter.

For example, if you look at `src/plugins/data/server/plugin.ts`, it receives an `initializerConfig` parameter. In your own server side plugin you could do `initializerContext.config.get('...')`.

I hope this points you out in the right direction!

Hi Liza, Thanks for the prompt reply.

ok, I will try to work on the solution that u give. I assuming the Discover module is also setup and structure like a plugin. Am I correct?
