Documentation

For the complete usage of go-slug, see the full package docs.

Example

Packing or unpacking a slug is pretty straight forward as shown in the following example:

package main

import (
	"bytes"
	"io/ioutil"
	"log"
	"os"

	slug "github.com/hashicorp/go-slug"
)

func main() {
	// First create a buffer for storing the slug.
	buf := bytes.NewBuffer(nil)

	// Then call the Pack function with a directory path containing the
	// configuration files and an io.Writer to write the slug to.
	if _, err := slug.Pack("testdata/archive-dir", buf, false); err != nil {
		log.Fatal(err)
	}

	// Create a directory to unpack the slug contents into.
	dst, err := ioutil.TempDir("", "slug")
	if err != nil {
		log.Fatal(err)
	}
	defer os.RemoveAll(dst)

	// Unpacking a slug is done by calling the Unpack function with an
	// io.Reader to read the slug from and a directory path of an existing
	// directory to store the unpacked configuration files.
	if err := slug.Unpack(buf, dst); err != nil {
		log.Fatal(err)
	}
}
