Types

type Command

type Command struct {
	// Git contains information about the git repo to fetch
	Git *kptfilev1.Git

	// Destination is the output directory to clone the package to.  Defaults to the name of the package --
	// either the base repo name, or the base subdirectory name.
	Destination string

	// Name is the name to give the package.  Defaults to the destination.
	Name string

	// UpdateStrategy is the strategy that will be configured in the package
	// Kptfile. This determines how changes will be merged when updating the
	// package.
	UpdateStrategy kptfilev1.UpdateStrategyType
}

Command fetches a package from a git repository, copies it to a local directory, and expands any remote subpackages.

Example

package main

import (
	"github.com/GoogleContainerTools/kpt/internal/printer/fake"
	"github.com/GoogleContainerTools/kpt/internal/util/get"

	kptfilev1 "github.com/GoogleContainerTools/kpt/pkg/api/kptfile/v1"
)

func main() {
	err := get.Command{Git: &kptfilev1.Git{
		Repo: "https://github.com/example-org/example-repo",
		Ref:  "v1.0",
	}}.Run(fake.CtxWithDefaultPrinter())
	if err != nil {
		// handle error
	}
}

Example (Branch)

		Repo: "https://github.com/example-org/example-repo",
