Overview

Package snapshots provides information and interaction with snapshots in the OpenStack Block Storage service. A snapshot is a point in time copy of the data contained in an external storage volume, and can be controlled programmatically.

Example to list Snapshots 

allPages, err := snapshots.List(client, snapshots.ListOpts{}).AllPages()
if err != nil{
	panic(err)
}
snapshots, err := snapshots.ExtractSnapshots(allPages)
if err != nil{
	panic(err)
}
for _,s := range snapshots{
	fmt.Println(s)
}

Example to get a Snapshot 

snapshotID := "4a584cae-e4ce-429b-9154-d4c9eb8fda4c"
snapshot, err := snapshots.Get(client, snapshotID).Extract()
if err != nil{
	panic(err)
}
fmt.Println(snapshot)

Example to create a Snapshot 

snapshot, err := snapshots.Create(client, snapshots.CreateOpts{
	Name:"snapshot_001",
	VolumeID:"5aa119a8-d25b-45a7-8d1b-88e127885635",
}).Extract()
if err != nil{
	panic(err)
}
fmt.Println(snapshot)

Example to delete a Snapshot 

snapshotID := "4a584cae-e4ce-429b-9154-d4c9eb8fda4c"
err := snapshots.Delete(client, snapshotID).ExtractErr()
if err != nil{
	panic(err)
}

Example to update a Snapshot 

snapshotID := "4a584cae-e4ce-429b-9154-d4c9eb8fda4c"
snapshot, err = snapshots.Update(client, snapshotID, snapshots.UpdateOpts{
	Name: "snapshot_002",
	Description:"description_002",
}).Extract()
if err != nil{
	panic(err)
}
fmt.Println(snapshot)
