Examples

Deploying a static file server.

  • Let's start with a basic go static file server, copy paste below to server.go

     package main

 import (
     "log"
     "net/http"
 )

 func main() {
     fs := http.FileServer(http.Dir("static"))
     http.Handle("/", fs)

     log.Println("Listening...on 8080")
     http.ListenAndServe(":8080", nil)
 }

  • Now build server.go

     $ GOOS=linux go build server.go

  • Prepare the HTML content.

    $ mkdir static
$ cd static

    Create hello.html

    <!doctype html>
<html>
<head>
<meta charset="utf-8">
    <title>A static page</title>
</head>
<body>
    <h1>Hello from a static page</h1>
</body>
</html>

  • Create a config file config.json

    {
    "Dirs" : ["static"]
}

    The directory structure should look like below after these steps.

    .
├── config.json
├── server
└── static
    └── hello.html

  • Package and deploy

     $ ops run -p 8080 -c config.json server

    Notice that we are using KVM user-mode networking and have to forward host port 8080 to VM.

  • Curl it

    curl http://localhost:8080/hello.html
