variable boundary_bin is not declared

[KuberDriver]

While executing command as per the guide:

terraform apply -target module.aws -var boundary_bin=/usr/bin/boundary will result:

Error: Value for undeclared variable

A variable named "boundary_bin" was assigned on the command line, but the root
module does not declare a variable of that name. To use this value, add a
"variable" block to the configuration

Guess users are required to create variables.tf locally and declare _boundarybin as per suggestion.
