Run Go Service in Docker

Run Go Service in Docker. Why use Docker at all? By using Docker, you can create a neat deploy system for yourself. You can easily change the port for Go web server without changing the Go code itself. You can run multiple different databases at the same time.

Why use Docker at all?

Of course, you can create Go executable for every system and you can run it where-ever you want. That’s true.

By using Docker, you can create a neat deploy system for yourself. And you do not care, what system actually runs on the final machine. You only want the machine to run Docker. You can easily stop and start multiple programs (multiple services if you like this terminology). You can easily change the port for Go web server without changing the Go code itself. You can run multiple different databases at the same time.

You can do a lot using Docker and I advise you to invest time to learn it.

For those of you not familiar with Docker, I recommend Bret Fisher’s Docker Mastery. This helped me to move from “what the hell is Docker” to “great, what else can I use Docker for”.

And for those of you already familiar with Docker, but want to know more, this talk can give you much more understanding about containers at all.
