Enables or disables the header HSTS in servers running SSL. HTTP Strict Transport Security (often abbreviated as HSTS) is a security feature (HTTP header) that tell browsers that it should only be communicated with using HTTPS, instead of using HTTP. It provides protection against protocol downgrade attacks and cookie theft.

Since 1.9.13 NGINX will not retry non-idempotent requests (POST, LOCK, PATCH) in case of an error in the upstream server. The previous behavior can be restored using the value "true".

Sets the bucket size for the map variables hash tables. The details of setting up hash tables are provided in a separate document.
Sets the size of the SSL buffer used for sending data. The default of 4k helps NGINX to improve TLS Time To First Byte (TTTFB). https://www.igvita.com/2013/12/16/optimizing-nginx-tls-time-to-first-byte/
Sets the ciphers list to enable. The ciphers are specified in the format understood by the OpenSSL library.
The default cipher list is:
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256.
The ordering of a ciphersuite is very important because it decides which algorithms are going to be selected in priority. The recommendation above prioritizes algorithms that provide perfect forward secrecy.
Please check the Mozilla SSL Configuration Generator.
Sets the name of the secret that contains Diffie-Hellman key to help with "Perfect Forward Secrecy".

Sets the time during which the specified number of unsuccessful attempts to communicate with the server should happen to consider the server unavailable.
Enables or disables compression of HTTP responses using the "gzip" module.

Sets custom headers from a configmap before sending traffic to the client. See proxy-set-headers example
Sets the addresses on which the server will accept requests instead of *. It should be noted that these addresses must exist in the runtime environment or the controller will crash loop.
