Overview

Package images enables management and retrieval of images from the OpenStack Image Service.

Example to List Images 

images.ListOpts{
	Owner: "a7509e1ae65945fda83f3e52c6296017",
}

allPages, err := images.List(imagesClient, listOpts).AllPages()
if err != nil {
	panic(err)
}

allImages, err := images.ExtractImages(allPages)
if err != nil {
	panic(err)
}

for _, image := range allImages {
	fmt.Printf("%+v\n", image)
}

Example to Create an Image 

createOpts := images.CreateOpts{
	Name:       "image_name",
	Visibility: images.ImageVisibilityPrivate,
}

image, err := images.Create(imageClient, createOpts)
if err != nil {
	panic(err)
}

Example to Update an Image 

imageID := "1bea47ed-f6a9-463b-b423-14b9cca9ad27"

updateOpts := images.UpdateOpts{
	images.ReplaceImageName{
		NewName: "new_name",
	},
}

image, err := images.Update(imageClient, imageID, updateOpts).Extract()
if err != nil {
	panic(err)
}
