 | `--enable-dynamic-certificates`   | Dynamically serves certificates instead of reloading NGINX when certificates are created, updated, or deleted. Currently does not support OCSP stapling, so --enable-ssl-chain-completion must be turned off (default behaviour). Assuming the certificate is generated with a 2048 bit RSA key/cert pair, this feature can store roughly 5000 certificates. Once the backing Lua shared dictionary `certificate_data` is full, the least recently used certificate will be removed to store new ones. (enabled by default) |

 | `--enable-ssl-chain-completion`   | Autocomplete SSL certificate chains with missing intermediate CA certificates. A valid certificate chain is required to enable OCSP stapling. Certificates uploaded to Kubernetes must have the "Authority Information Access" X.509 v3 extension for this to succeed. (default true) |

 | `--health-check-path string`      | URL path of the health check endpoint. Configured inside the NGINX status server. All requests received on the port defined by the healthz-port parameter are forwarded internally to this path. (default "/healthz") |
