As a developer I prefer using systemd instead of containers to deploy Golang applications.

Without (Docker) containers it is:

- build Go binary and install it in production server

- write and enable the systemd unit file

With (Docker) containers it is:

- write Dockerfile

- install Docker in production server

- build Docker image and deploy container in production server

I get the appealing of containers when one production server is used for multiple applications (e.g., you have a Golang app and a redis cache), but the example above I think containers a bit of an overkill.
