Simple HTTPS |
Simple HTTPS on a custom domain, the Urbit way |
Urbit needs to have its http service bound to port 80 (It will annouce what port it binds to in the terminal on start up). On linux, you can allow Urbit to bind to this port with the setcap
command (e.g. sudo setcap 'cap_net_bind_service=+ep' ~/urbit-v0.10.8-linux64/urbit
).
If on a LAN you may need to forward port 80 to and from your router and device running Urbit. Many home internet service providers block port 80 for their customers, so this may not work at all.
I use freedns.afraid.org because they provide real Type A DNS Records, and they have a domain I like (you'll see). Not all free DNS services will use this method, some do forwarding with nginx or other shenanigans. We want Let's Encrypt to work, so we want something simple and direct like an A Record.
(Duck DNS is also known to work and lets you login with multiple different OAuth providers.)
After you create an account, create a subdomain
If you don't like the short list of recommended domains, click Many many more available to see a larger list
Choose a domain, and complete setup. If you're uncertain about your external IP address, you can run +http://ifconfig.io/ip
in your Urbit's dojo to find out.
Now let's navigate to the sumbdomain that was just setup, to make sure it worked.
It works, but we need to get https working. Let's run some commands in dojo.
First, make sure Urbit's acme app is running with |start %acme
Next run :acme &path /topleveldomain/domain/subdomain
And it completed successfully!
