version

A go-language package for managing k0s version numbers. It is based on hashicorp/go-version but adds sorting and comparison capabilities for the k0s version numbering scheme which requires additional sorting by the build tag.

Usage

Basic comparison

import (
	"fmt"
	"github.com/k0sproject/version"
)

func main() {
	a := version.MustParse("1.23.3+k0s.1")
	b := version.MustParse("1.23.3+k0s.2")
	fmt.Printf("a is greater than b: %t\n", a.GreaterThan(b))
	fmt.Printf("a is less than b: %t\n", a.LessThan(b))
	fmt.Printf("a is equal to b: %t\n", a.Equal(b))
}

Outputs:

a is greater than b: false
a is less than b: true
a is equal to b: false

Check online for latest version

import (
	"fmt"
	"github.com/k0sproject/version"
)

func main() {
	latest, err := version.Latest()
	if err != nil {
		panic(err)
	}
	fmt.Printf("Latest k0s version is: %s\n", latest)
}

k0s_sort executable

A command-line interface to the package. Can be used to sort lists of versions or to obtain the latest version number.

Usage: k0s_sort [options] [filename ...]
  -l	only print the latest version
  -o	print the latest version from online
  -s	omit prerelease versions
  -v	print k0s_sort version
