Steps to Install the demo

Service to receive Alexa commands

Use script install otc_service.sh on a small machine with EIP on the internet.

Quickly create a self-signed certificate for testing

> openssl req -x509 -sha256 -nodes-days 730  -newkey rsa:4096 -keyout alexa_otc_ss.key -out alexa_otc_cert.pem 

Open up internal firewall on centos

> sudo firewall-cmd --permanent --zone=public --add-port=5443/tcp --add-service=https

Multi language support

Create a language label file (once):

cd src
pybabel extract -F babel.cfg -o messages.pot .

Start a new language (e.g. for language de):

cd src
pybabel init -i messages.pot -d translations -l de

Update the language label translation file with new/chaged labels:

cd src
pybabel update -i messages.pot -d translations 

Finally, compile the messages:

cd src
pybabel compile -d translations
