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.
I started by forking the apache2 charm, because I just want to play around.
You can try it out:
juju bootstrap
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.
