Platform.sh supports building and deploying applications written in Go. They are compiled during the Build hook phase, and support both committed dependencies and download-on-demand.

Supported versions

  • 1.8

To specify a Go container, use the type property in your .platform.app.yaml.

type: 'golang:1.8'


Platform.sh recommends a modified version of the CloudFlare Hellogpher Makefile to manage compilation with the GOPATH. When run on Platform.sh in the build step, the Makefile will download any dependencies not already present in the vendor directory, set a fake GOPATH, and build the application.

Platform.sh variables

Platform.sh exposes relationships and other configuration as environment variables. To make them easier to access you should use the provided GoHelper library. Most notably, it allows a program to determine at runtime what HTTP port it should listen on and what the credentials are to access other services.

package main

import (
    _ "github.com/go-sql-driver/mysql"
    psh "github.com/platformsh/gohelper"

func main() {

    p, err := psh.NewPlatformInfo()

    if err != nil {
        panic("Not in a Platform.sh Environment.")

    http.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) {
        // ...

    http.ListenAndServe(":"+p.Port, nil)

Running the application

Your compiled Go application will be placed in the bin directory by the Makefile's build command, and named according to the IMPORT_PATH specified in the file. It should be executed by the web.commands.start directive in .platform.app.yaml. Should the program terminate for any reason it will be automatically restarted.

        socket_family: tcp
        protocol: http

        start: |

            allow: false
            passthru: true

Note that there will still be an Nginx proxy server sitting in front of your application. If desired, certain paths may be served directly by Nginx without hitting your application (for static files, primarily) or you may route all requests to the Go application unconditionally, as in the example above.

Project templates

Platform.sh offers a project templates for Go applications using the structure described above. It can be used as a starting point or reference for building your own website or web application.
