This command exposes a variety of controls via environment variables. You can
set environments using "export KEY=VALUE" (Linux/macOS) or "set KEY=VALUE" (Windows). On Linux,
you can also set environments by pre-pending key value pairs: "KEY=VALUE KEY2=VALUE2 hydra"

All possible controls are listed below. The host process additionally exposes a few flags, which are listed below
the controls section.


CORE CONTROLS
=============

` + databaseUrl + `

- LOG_LEVEL: Set the log level, supports "panic", "fatal", "error", "warn", "info" and "debug". Defaults to "info".
	Example: LOG_LEVEL=panic

- LOG_FORMAT: Leave empty for text based log format, or set to "json" for JSON formatting.
	Example: LOG_FORMAT="json"

HTTP(S) CONTROLS
==============
` + tlsMessage + `

- HOST: The host to listen on.
	--------------------------------------------------------------
	Default: HOST="" (all interfaces)
	--------------------------------------------------------------

- PORT: The port to listen on.
	--------------------------------------------------------------
	Default: PORT="4466"
	--------------------------------------------------------------


AUTHENTICATORS
==============

- The OAuth 2.0 Token Introspection Authenticator is capable of resolving OAuth2 access tokens to a subject and a set
	of granted scopes using the OAuth 2.0 Introspection standard.

	- AUTHENTICATOR_OAUTH2_INTROSPECTION_CLIENT_ID: The client ID to be used when performing the OAuth 2.0 Introspection request.
		Example: AUTHENTICATOR_OAUTH2_INTROSPECTION_CLIENT_ID=my_client

	- AUTHENTICATOR_OAUTH2_INTROSPECTION_CLIENT_SECRET: The client secret to be used when performing the OAuth 2.0 Introspection request.
		Example: AUTHENTICATOR_OAUTH2_INTROSPECTION_CLIENT_SECRET=my_secret

	- AUTHENTICATOR_OAUTH2_INTROSPECTION_SCOPE: The scope(s) (comma separated) required to perform the introspection request. If no scopes are
		required, leave this value empty.
		Example: AUTHENTICATOR_OAUTH2_INTROSPECTION_SCOPE=scopeA,scopeB

	- AUTHENTICATOR_OAUTH2_INTROSPECTION_TOKEN_URL: The OAuth2 Token Endpoint URL of the server
		Example: AUTHENTICATOR_OAUTH2_INTROSPECTION_TOKEN_URL=https://my-server/oauth2/token

	- AUTHENTICATOR_OAUTH2_INTROSPECTION_URL: The OAuth2 Introspection Endpoint URL of the server
		Example: AUTHENTICATOR_OAUTH2_INTROSPECTION_URL=https://my-server/oauth2/introspect

- The OAuth 2.0 Client Credentials Authenticator is capable of authentication OAuth 2.0 clients using the client credentials
	grant.

	- AUTHENTICATOR_OAUTH2_CLIENT_CREDENTIALS_TOKEN_URL: The OAuth2 Token Endpoint URL of the server
		Example: AUTHENTICATOR_OAUTH2_CLIENT_CREDENTIALS_TOKEN_URL=https://my-server/oauth2/token
` + corsMessage + `
DEBUG CONTROLS
==============

- PROFILING: Set "PROFILING=cpu" to enable cpu profiling and "PROFILING=memory" to enable memory profiling.
	It is not possible to do both at the same time.
	Example: PROFILING=cpu

	Run: server.RunServe(logger, Version, GitHash, BuildTime),
