Manage Go dependencies with godep

This tutorial explains how to deploy a Go application which is using godep to manage its dependencies. To handle the version management of the dependencies, please follow the offical godep guide, this page will focus on the deployment of the app.

Configuration

During the deployment of a godep-ed application, we’re looking at different special keys in the configuration file Godeps/Godeps.json to give our deployment system the data we need to deploy correctly the application:

  • GoVersion (String): the version of Go you would like Scalingo to use when compiling your code. If not specified, we’ll install the last stable version.

  • Packages (Array of strings): What should be installed of your application. We’ll default to ["."] to install the package at the top level of your project, if your executable is in the cmd directory, another common choice is ["./cmd/..."]. If you want to install all the packages including those which are vendored, you can use ["./..."].

  • ImportPath (String): Name of the package installed during the deployment. If no Packages are present, the binary will have the name of the last part of the complete package name: github.com/Scalingo/sample-go-martini will create a binary named sample-go-martini.

Here is an example with godep: https://github.com/Scalingo/sample-go-martini.

{
  ...
  "ImportPath": "github.com/Scalingo/sample-go-martini"
  "GoVersion": "go1.10",
  "Packages": ["."],
  ...
}
