Deploying a Static File Server

Lets start with a basic go static file server, copy-and-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 named config.json:
{
"Dirs" : ["static"],
"Files":["/lib/x86_64-linux-gnu/libnss_dns.so.2", "/etc/ssl/certs/ca-certificates.crt"]
}
If you are on linux you can use the above example to enable dns/tls, otherwise you can use this for local Mac examples.
Note: This is more than likely to change in the very near future.
{
"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
