Overview

Package aggregates manages information about the host aggregates in the OpenStack cloud.

Example of Create Aggregate

opts := aggregates.CreateOpts{
	Name:             "name",
	AvailabilityZone: "london",
}

aggregate, err := aggregates.Create(computeClient, opts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)

Example of Show Aggregate Details

aggregateID := 42
aggregate, err := aggregates.Get(computeClient, aggregateID).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)

Example of Delete Aggregate

aggregateID := 32
err := aggregates.Delete(computeClient, aggregateID).ExtractErr()
if err != nil {
	panic(err)
}

Example of Update Aggregate

aggregateID := 42
opts := aggregates.UpdateOpts{
	Name:             "new_name",
	AvailabilityZone: "nova2",
}

aggregate, err := aggregates.Update(computeClient, aggregateID, opts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)

Example of Retrieving list of all aggregates

allPages, err := aggregates.List(computeClient).AllPages()
if err != nil {
	panic(err)
}

allAggregates, err := aggregates.ExtractAggregates(allPages)
if err != nil {
	panic(err)
}

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

Example of Add Host

aggregateID := 22
opts := aggregates.AddHostOpts{
	Host: "newhost-cmp1",
}

aggregate, err := aggregates.AddHost(computeClient, aggregateID, opts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)

Example of Remove Host

aggregateID := 22
opts := aggregates.RemoveHostOpts{
	Host: "newhost-cmp1",
}

aggregate, err := aggregates.RemoveHost(computeClient, aggregateID, opts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)

Example of Create or Update Metadata

aggregateID := 22
opts := aggregates.SetMetadata{
	Metadata: map[string]string{"key": "value"},
}

aggregate, err := aggregates.SetMetadata(computeClient, aggregateID, opts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", aggregate)
