Go is a compiled programminag language similar to C. Applications written in Go are compiled to static binaries, with an aim to simplify deployment. Many popular data center applications and tools are written in Go.

The debops.golang role was designed to support multiple ways of deploying Go applications using Ansible:

  • installation from an APT package, when available;
  • installation from source by cloning the application repositories and building the binaries in situ;
  • installation of a precompiled binary downloaded from a remote source;

Installation via APT packages is a preferred method, since this saves compile time and does not require access to third-party services. The other installation methods can be used when a given Go application is not available in a given OS release, or the upstream does not provide APT repositories.

The debops.golang role should be used as a dependent Ansible role in other role playbooks, to simplify installation of the Go applications. Further service configuration should be done in a given application role. Usage via the Ansible inventory is, of course, still possible but might not be optimal.
