Installing TLS/SSL using Let's Encrypt

Reporting that everything worked fine with hass-in-container on raspbian-buster,
EXCEPT that the android-companion-app cannot contact from inseid my local-network,
since my router does not support lopback, so i’m stuck with https://<local-ip>:8132,
which needs manually overriding security warnings - i guess, the browser embedded in the android-app does not prompt for those overrides.
I can still loginto hass using a browser page, but presence does not work when inside my network.

I can think of 3 ways out:

  1. proxy HASS though apache/nginx so SSL terminates on the proxy, and 8132 remain plain http;
  2. fix android-app to ignore the security warning when accessing the internal-URL / from home-wifi, or even have a separate tick-option to allow this exception;
  3. SplitBrain DNS.

Any suggestion welcomed?

Just trying this out, but was wondering if Option 2 would work in a Docker HA installation (on Lubuntu)?
My concern is that the certbot script would be located correctly, and that there would be no permissions issues?

shell_command:
  renew_ssl: certbot renew --quiet --no-self-upgrade --standalone --preferred-challenges http-01

Edit: if I try running the renew_ssl command from the HA console I get an error (return code 127)

Excellent post! I spent hours looking at how to have SSL in my home assistant core mounted on docker-compose.
I was finally able to do it by following his steps and adding the corresponding volume:

volumes:
  - /home/pi/homeassistant:/config
  - /etc/letsencrypt/archive/mydomain.duckdns.org:/config/ssl
  - /etc/localtime:/etc/localtime:ro

And this in configuration.yaml of Home Assistant:

http:
ssl_certificate: /config/ssl/fullchain1.pem
ssl_key: /config/ssl/privkey1.pem

To renew, your commands didn’t work for me, but this command did work:

certbot renew --cert-name mydomain.duckdns.org

Hope this can help someone if they have the same problems as me, thanks for your tutorial!

Does this tutorial works for DYNU DDNS?

It works with any DYN DNS. You just need a fixed domain name.

I’m working on creating an update but lack the ability to post it. I’ll reply back in this thread once I do.

EDIT: It looks like I’ve been granted the necessary rights to do so! :tada:
