Checking HTTPS

We copy the certificate from the container:

sudo docker cp  flask_nginx_2_loadbalancer_1:/etc/nginx/server.crt /usr/local/share/ca-certificates/

Run to update the list of trusted certificates:

sudo update-ca-certificates

Add host:

chmod +x host.sh
sudo ./host.sh

curl -s -L https://flask.com && echo

If output like:

Hello, World!
