I stumbled upon https://launchpad.net/~ondrej/+archive/ubuntu/apache2 when looking at http2 options for apache and it seemed to me that it might be easy to add support for http2 on any ubuntu system.
You can try it out:
juju deploy cs:~evarlast/trusty/apache2 –to 0
juju set apache2 ssl_cert=SELFSIGNED
juju set apache2 enable_modules=ssl
juju run –service apache2 ‘a2ensite default-ssl’
juju run –service apache2 ‘service apache2 reload’
Now run `juju status` to get the IP address of the node and try it out.
Open your browsers dev tools and confirm that http2 was used.
