Integrating OpenZiti with a Golang TLS server

That's great though. I wondered how you did generate that json file. Did you try with ziti edge cmd?
Also in your summary you mentioned like

So, where I can find that file.

In the readme file, I grabbed this below GitHub - openziti/sdk-golang: Ziti SDK for Golang

Prerequisite: Ziti Enrollment token in JWT format (e.g. device.jwt)

Run enrollment process to generate SDK configuration file -- device.json

I again confused here, do I need to setup those before I take step ahead to run the application? If so, how I can generate those. Any links plz?
