在IBM的BlueMix上使用golang

由于BlueMix与cloudfoundry兼容,因此可以使用cf命令进行操作。

安装cf

gem install cf

设定目标

$ cf target https://api.ng.bluemix.net
Setting target to https://api.ng.bluemix.net... OK

登入

$ cf login
target: https://api.ng.bluemix.net

写go语言的代码

简单的东西

package main

import (
    "net/http"
    "os"
)

func main() {
    port := os.Getenv("PORT")
    if port == "" {
        port = "8080"
    }
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello World"))
    })
    http.ListenAndServe(":"+port, nil)
}

创建 godir

$ echo server > .godir

创建 Procfile

$ echo "web: server" > Procfile

指定构建包并推送

$ cf push --name mattn --buildpack https://github.com/michaljemala/cloudfoundry-buildpack-go.git
