Kubernetes Ingress Controller
2.3.x
You are browsing documentation for an outdated version. See the latest documentation here.

CLI Arguments

Various settings and configurations of the controller can be tweaked using CLI flags.

Environment variables

Each flag defined in the table below can also be configured using an environment variable. The name of the environment variable is CONTROLLER_ string followed by the name of flag in uppercase.

For example, --ingress-class can be configured using the following environment variable:

CONTROLLER_INGRESS_CLASS=kong-foobar

It is recommended that all the configuration is done via environment variables and not CLI flags.
