The default value is true.

Specified by:

applyEnvironmentVariableOverrides in interface ZeebeClientBuilder

gatewayAddress

public ZeebeClientBuilder gatewayAddress(String gatewayAddress)

Specified by:

gatewayAddress in interface ZeebeClientBuilder

Parameters:

gatewayAddress - the IP socket address of a gateway that the client can initially connect to. Must be in format host:port. The default value is 0.0.0.0:26500 .
