Overview

Package flavors provides information and interaction with the flavor API in the OpenStack Compute service.

A flavor is an available hardware configuration for a server. Each flavor has a unique combination of disk space, memory capacity and priority for CPU time.

Example to List Flavors 

listOpts := flavors.ListOpts{
	AccessType: flavors.PublicAccess,
}

allPages, err := flavors.ListDetail(computeClient, listOpts).AllPages()
if err != nil {
	panic(err)
}

allFlavors, err := flavors.ExtractFlavors(allPages)
if err != nil {
	panic(err)
}

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

Example to Create a Flavor 

createOpts := flavors.CreateOpts{
	ID:         "1",
	Name:       "m1.tiny",
	Disk:       golangsdk.IntToPointer(1),
	RAM:        512,
	VCPUs:      1,
	RxTxFactor: 1.0,
}

flavor, err := flavors.Create(computeClient, createOpts).Extract()
if err != nil {
	panic(err)
}

Example to List Flavor Access 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

allPages, err := flavors.ListAccesses(computeClient, flavorID).AllPages()
if err != nil {
	panic(err)
}

allAccesses, err := flavors.ExtractAccesses(allPages)
if err != nil {
	panic(err)
}

for _, access := range allAccesses {
	fmt.Printf("%+v", access)
}

Example to Grant Access to a Flavor 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

accessOpts := flavors.AddAccessOpts{
	Tenant: "15153a0979884b59b0592248ef947921",
}

accessList, err := flavors.AddAccess(computeClient, flavor.ID, accessOpts).Extract()
if err != nil {
	panic(err)
}

Example to Remove/Revoke Access to a Flavor 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

accessOpts := flavors.RemoveAccessOpts{
	Tenant: "15153a0979884b59b0592248ef947921",
}

accessList, err := flavors.RemoveAccess(computeClient, flavor.ID, accessOpts).Extract()
if err != nil {
	panic(err)
}

Example to Create Extra Specs for a Flavor 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

createOpts := flavors.ExtraSpecsOpts{
	"hw:cpu_policy":        "CPU-POLICY",
	"hw:cpu_thread_policy": "CPU-THREAD-POLICY",
}
createdExtraSpecs, err := flavors.CreateExtraSpecs(computeClient, flavorID, createOpts).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("%+v", createdExtraSpecs)

Example to Get Extra Specs for a Flavor 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

extraSpecs, err := flavors.ListExtraSpecs(computeClient, flavorID).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("%+v", extraSpecs)

Example to Update Extra Specs for a Flavor 

flavorID := "e91758d6-a54a-4778-ad72-0c73a1cb695b"

updateOpts := flavors.ExtraSpecsOpts{
	"hw:cpu_thread_policy": "CPU-THREAD-POLICY-UPDATED",
}
updatedExtraSpec, err := flavors.UpdateExtraSpec(computeClient, flavorID, updateOpts).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("%+v", updatedExtraSpec)

Example to Delete an Extra Spec for a Flavor

const (
	// PublicAccess returns public flavors and private flavors associated with
	// that project.
