Deploying a Static File Server
Lets start with a basic go static file server, copy-and-paste below to server.go:
1
package main
2
​
3
import (
4
    "log"
5
    "net/http"
6
)
7
​
8
func main() {
9
    fs := http.FileServer(http.Dir("static"))
10
    http.Handle("/", fs)
11
​
12
    log.Println("Listening...on 8080")
13
    http.ListenAndServe(":8080", nil)
14
}
Copied!
Now build server.go:
1
$ GOOS=linux go build server.go
Copied!
Prepare the HTML content:
1
$ mkdir static
2
$ cd static
Copied!
Create hello.html:
1
<!doctype html>
2
<html>
3
<head>
4
<meta charset="utf-8">
5
    <title>A static page</title>
6
</head>
7
<body>
8
    <h1>Hello from a static page</h1>
9
</body>
10
</html>
Copied!
Create a config file named config.json:
1
{
2
    "Dirs" : ["static"],
3
    "Files":["/lib/x86_64-linux-gnu/libnss_dns.so.2", "/etc/ssl/certs/ca-certificates.crt"]
4
}
Copied!
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.
1
{
2
    "Dirs" : ["static"]
3
}
Copied!
The directory structure should look like below after these steps:
1
.
2
├── config.json
3
├── server
4
└── static
5
    └── hello.html
Copied!
Package and deploy:
1
$ ops run -p 8080 -c config.json server
Copied!
Notice that we are using KVM user-mode networking and have to forward host port 8080 to VM.
Curl it:
1
curl http://localhost:8080/hello.html
Copied!
