Overview ¶
Package migrate provides functionality to migrate servers that have been provisioned by the OpenStack Compute service.
Example of Migrate Server (migrate Action)
serverID := "b16ba811-199d-4ffd-8839-ba96c1185a67"
err := migrate.Migrate(computeClient, serverID).ExtractErr()
if err != nil {
panic(err)
}
Example of Live-Migrate Server (os-migrateLive Action)
serverID := "b16ba811-199d-4ffd-8839-ba96c1185a67"
host := "01c0cadef72d47e28a672a76060d492c"
blockMigration := false
migrationOpts := migrate.LiveMigrateOpts{
Host: &host,
BlockMigration: &blockMigration,
}
err := migrate.LiveMigrate(computeClient, serverID, migrationOpts).ExtractErr()
if err != nil {
panic(err)
}

Types ¶
type LiveMigrateOpts ¶
type LiveMigrateOpts struct {
// The host to which to migrate the server.
// If this parameter is None, the scheduler chooses a host.
Host *string `json:"host"`
// Set to True to migrate local disks by using block migration.
// If the source or destination host uses shared storage and you set
// this value to True, the live migration fails.
BlockMigration *bool `json:"block_migration,omitempty"`
// Set to True to enable over commit when the destination host is checked
// for available disk space. Set to False to disable over commit. This setting
// affects only the libvirt virt driver.
DiskOverCommit *bool `json:"disk_over_commit,omitempty"`
}
LiveMigrateOpts specifies parameters of live migrate action.
func (LiveMigrateOpts) ToLiveMigrateMap ¶
func (opts LiveMigrateOpts) ToLiveMigrateMap() (map[string]interface{}, error)
ToLiveMigrateMap constructs a request body from LiveMigrateOpts.
type LiveMigrateOptsBuilder ¶
LiveMigrateOptsBuilder allows extensions to add additional parameters to the LiveMigrate request.
type MigrateResult ¶
type MigrateResult struct {
gophercloud.ErrResult
}
MigrateResult is the response from a Migrate operation. Call its ExtractErr method to determine if the request suceeded or failed.
func LiveMigrate ¶
func LiveMigrate(client *gophercloud.ServiceClient, id string, opts LiveMigrateOptsBuilder) (r MigrateResult)
LiveMigrate will initiate a live-migration (without rebooting) of the instance to another host.
func Migrate ¶
func Migrate(client *gophercloud.ServiceClient, id string) (r MigrateResult)
Migrate will initiate a migration of the instance to another host.
