Provides a forwarding HTTPS server which transparently fetches and caches certificates via Let's Encrypt. This must run on 443 and 80 (just forwards to https://) and can't coexist with any other web server on your machine.
Why? This is so you can host random and long-lived services publicly on the internet—perfect for other services which don't care about certificates or HTTPS at all, and might be provided by Node or Go on a random high port (e.g., some dumb service running on localhost:8080).
Note! This doesn't magic up domain names. You would use this service only if you're able to point DNS records to the IP address of a machine you're running this on, and that the machine is able to handle incoming requests on port 443 and 80 (e.g., on a home network, you'd have to set up port forwarding on your router).
Configure this via /var/snap/https-forward/common/config, which is empty after install. It should be authored like this:
# hostname forward-to optional-basic-auth
blah.example.com 192.168.86.24:7999 user:pass
user-only.example.com localhost:9002 user # accepts any password
# ... specify host with '.' to suffix all following
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install https-forward, simply use the following command:
