Encrypting communications in Kibana or Logstash on Docker

Hi there,

I have follow this "[Encrypting communications in an Elasticsearch Docker Container](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/configuring-tls-docker.html#configuring-tls-docker)", and my questions are

1. after docker-compose up, I was not able to login to https://localhost:9200 with password that written in .env file; therefore I try the "elasticsearch-setup-passwords" tool to generate all user's password, also include elastic user's password to make me access. Not sure why it is not getting the right password (ELASTIC_PASSWORD) in .env file?

2. The document only provide docker compose file with elaticsearch properties, do we have Kibana and Logstash's part of setting up ssl/tls?

Note: I entered to the elasticsearch, and I did see the certs folder with all the *.crt and *.key files。
