The path to the certificate is specified in the server.ssl.key-store parameter, and is set to classpath:keystore/edge.p12. This means that the certificate will be picked up on the classpath from the location keystore/edge.p12.
The password for the certificate is specified in the server.ssl.key-store-password parameter.
To indicate that the edge server talks HTTPS and not HTTP, we also change the port from 8080 to 8443 in the server.port parameter.
