🚀 Distronaut

Distronaut is a tool that travel through the internet to find distribution ISO links and metadata, making it easier for you to monitor new releases, burn install medias or build your own ISO bank archive.

⌨️ CLI

🔨 Installation

Using a pre-built binary:

go install github.com/ovh/distronaut@latest

Building from source

make

🪛 Usage

Use fetch command to retrieve a JSON from configured sources:

distronaut fetch -c config/sources.yml -f 'debian'

Output is similar to below:

[
  {
    "Source": "Debian",
    "Family": "Linux",
    "Distribution": "Debian (formerly Debian GNU/Linux)",
    "Website": "http://www.debian.org/",
    "Documentation": "http://www.debian.org/doc/",
    "Status": "Active",
    "Versions": [
      {
        "Url": "https://cdimage.debian.org/debian-cd/11.4.0/amd64/iso-cd/debian-11.4.0-amd64-netinst.iso",
        "Hash": "sha256:d490a35d36030592839f24e468a5b818c919943967012037d6ab3d65d030ef7f",
        "Version": "11.4.0",
        "Arch": "amd64",
        "Meta": {
          "release": "2021-08-14"
        }
      }
    ]
  }
]

Additional metadata are scrapped from distrowatch.com.

👨‍💻 Programmatic usage

This package can also be imported within another golang codebase:

package main

import (
	"encoding/json"
	"fmt"
	"github.com/ovh/distronaut/pkg/distro"
)

func main() {
	src, _ := distro.FetchSources("config/sources.yml", "debian")
	j, _ := json.MarshalIndent(src, "", "  ")
	fmt.Println(string(j))
}

🌕 Configuring new sources

Open your configuration file and add a new entry, containing:

• name is a friendly name for your new source (can also be used for filtering)
• url is the source URL pattern
  • each route parameter is indicated by a colon (:)
• patterns is a map containing:
  • :* are regex patterns that are matched by defined route parameter
    • each route parameter can be back-referenced using \k<:name> syntax
  • .hash.* contains all hash related settings
    • .hash.file is a regex pattern matching the file containing hashes
    • .hash.pattern is a regex pattern capturing the hash from a given iso (that can be back-referenced with \k<iso>)
    • .hash.algo is the name of the hash algorithm
  • .meta.* contains all metadata related settings
    • .meta.source must be set to distrowatch (only metadata source supported for now)
    • .meta.id is the distro handle on distrowatch
    • .meta.version is a regex pattern matching the version as it is referenced on distrowatch

Example source:

- name: Debian
  url: https://cdimage.debian.org/debian-cd/:version/:arch/iso-cd/:iso
  patterns:
    :version: ^(\d+\.\d+(?:\.\d+)?)\/$
    :arch: ^(amd64|arm64)\/$
    :iso: ^debian-\k<version>-\k<arch>-netinst\.iso$
    .hash.file: SHA256SUMS
    .hash.algo: sha256
    .hash.pattern: (?m)^([0-9a-f]{64})\s+\k<iso>
    .meta.source: distrowatch
    .meta.id: debian
    .meta.version: (\d+)
