Cerebro auth with Search Guard

I am new to Search Guard, I have a single machine running a fresh Elasticsearch 6.4.0 install and Search Guard.

There is a utility called Cerebro that provides a graphical interface to Elasticsearch clusters.

it is listed in supported plugins:

The config file is simple, I’ve tried admin/admin in the Authentication section, which seems to be password protection for the Cerebro app itself, and in the hosts section. This shows a plain text link, switching to https generates some errors on console from Cerebro, which I have included below.

Is there a simple solution already worked out for this?

Authentication

auth = {

type: basic

settings: {

username = “admin”

password = “admin”

}

}

A list of known hosts

hosts = [

{

host = “http://localhost:9200

name = “hotpot”

auth = {

username = “admin”

password = “admin”

}

}

]

begin Cerebro errors with https

Hi, for problems with self signed certs try something like this:
play.ws.ssl.loose.acceptAnyCertificate = true

and host should be using https
host = “https://localhost:9200”
