Continue with installation? [y/N]y

This is just a warning to inform you that the plugin requires additional permissions than those required by the core Elasticsearch process. If you hit y, those permissions will be automatically granted. See: Installing plugins with custom docker image warning message

As Elasticsearch plugins have to be installed on each node, we have documentation on how to easily achieve that with ECK as well.

Thanks I was able to use secure string to add keys
