2. HA Reverse Proxy

Now, if you want your home assistant to be reachable via URL or domain name then we need to jump into the configuration.yaml file inside the container. Assuming your container is called "home-assistant" we type in the following command inside the docker vm to jump inside the container

docker exec -it home-assistant /bin/bash

This will drop you inside the container as containter_number:/config#. We will then enter the configuration.yaml file with

vi configuration.yaml

Then you need to make sure that change your configuration file to this

# Loads default set of integrations. Do not remove.
default_config:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 10.56.4.1  #IP address of gateway or the VLAN network----> CHANGE THIS TO YOUR VALUES

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

It is clear that the http part is the one that is added. Adjust the values to your configuration and save the file. To start editing in view one would click on the letter "i". Make the edit. Once you are done hit ESC and then type the command ":wq" to write to it and quit. After that is done you should restart Home Assistant.
