Unable to Retain Instance State When Using Flags Library for Command Execution

[jielim36]

I am unable to call the same instance of ServiceA when implementing command-line operations using the flag library.

Specific Situation:

1. When triggering the addAdminCommand, the NewServiceA in the invoke function is called again, as evidenced by the logger being re-initialized and producing new output.
2. When initializing ServiceA, its Status field is set to "A". After modifying it to "B" through the command, an HTTP request to retrieve the Status field of ServiceA still returns "A".

Additional Note:

I'm posting this in Discussions because I am unsure whether the issue lies with dig or flag, or if it is simply a limitation of command-line operations being unable to share state across executions.

main.go:

// 1. DI
container.Provide(NewServiceA)

// 2. Pass container to command line tools (flag library)
addAdminCommand(container)

// 3. run app with container
RunApp(container)

serviceA.go:

type ServiceA {
	Status string
}

func NewServiceA() *ServiceA {
	logger.Info("Init ServieA")
	return &ServiceA{Status: "A"}
}

addAdminCommand.go:

func addAdminCommand(container) {
	container.Invoke(func(
		serviceA *service.ServiceA
	) {
		service.Status = "B"
	})
}
