Serve the user interface over HTTPS. The certificate and private key to be used must be placed in the
{{certificateDir}} directory with filenames
ui-cert.pem and
ui-key.pem before enabling
HTTPS, where ui-cert.pem is a PEM encoded X.509 certificate chain, and ui-key.pem is a PEM encoded PKCS#8
private key without a passphrase.
(for example, a self signed certificate can be generated at the command line meeting the above requirements
using OpenSSL 1.0.0 or later:
openssl req -new -x509 -nodes -days 365 -out ui-cert.pem -keyout ui-key.pem)
