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)
}

Functions ¶
func List ¶
func List(client *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager
List returns a Pager that allows you to iterate over a collection of Migrations.
Types ¶
type DeleteResult ¶
type DeleteResult struct {
gophercloud.ErrResult
}
DeleteResult is the response from a Delete operation. Call its ExtractErr to determine if the request succeeded or failed.
func Delete ¶
func Delete(client *gophercloud.ServiceClient, serverID, migrationID string) (r DeleteResult)
Delete deletes a migration action.
type ListOpts ¶
type ListOpts struct {
// Limit is the amount of containers to retrieve.
// New in version 2.59
Limit int `q:"limit"`
// Marker The ID of the last-seen item. Use the limit parameter to make an initial limited request and use the
// ID of the last-seen item from the response as the marker parameter value in a subsequent limited request.
// New in version 2.59
Marker string `q:"marker"`
// Hidden The ‘hidden’ setting of migration to filter. The ‘hidden’ flag is set if the value is 1.
// The ‘hidden’ flag is not set if the value is 0. But the ‘hidden’ setting of migration is always 0, so this parameter is useless to filter migrations.
Hidden int `q:"hidden"`
// Host The source/destination compute node of migration to filter.
Host string `q:"host"`
// MigrationType The type of migration to filter. Valid values are: evacuation,live-migration, migration, resize
MigrationType string `q:"migration_type"`
// Status The status of migration to filter.
Status string `q:"status"`
// ChangesSince filters the response by a date and time stamp when the migration last changed. New in version 2.59
ChangesSince string `q:"changes-since"`
// ChangesBefore Filters the response by a date and time stamp when the migration last changed. New in version 2.66
ChangesBefore string `q:"changes-before "`
// UserID Filter the migrations by the given user ID. New in version 2.80
UserID string `q:"user_id"`
// ProjectID Filter the migrations by the given project ID. New in version 2.80
ProjectID string `q:"project_id"`
}
ListOpts provides options to filter the List results.
func (ListOpts) ToContainerListQuery ¶
ToContainerListQuery formats a ListOpts into a query string.
type ListOptsBuilder ¶
ListOptsBuilder allows extensions to add additional parameters to the List request
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 MigrateOpts ¶
type MigrateOpts struct {
// The host to which to migrate the server.
// If this parameter is None, the scheduler chooses a host.
// Migrate Server (migrate Action) (v2.56)
Host *string `json:"host"`
}
MigrateOpts specifies parameters of live migrate action.
func (MigrateOpts) ToMigrateMap ¶
func (opts MigrateOpts) ToMigrateMap() (map[string]interface{}, error)
ToMigrateMap constructs a request body from MigrateOpts.
type MigrateOptsBuilder ¶
MigrateOptsBuilder allows extensions to add additional parameters to the Migrate 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, opts MigrateOptsBuilder) (r MigrateResult)
Migrate will initiate a migration of the instance to another host.
type Migration ¶
type Migration struct {
// ID The ID of the server migration.
ID int `json:"id"`
// CreatedAt The date and time when the resource was created.
CreatedAt string `json:"created_at"`
// DestCompute The target compute for a migration.
DestCompute string `json:"dest_compute"`
// DestHost The target node for a migration.
DestHost string `json:"dest_host"`
// InstanceUUID The UUID of the server.
InstanceUUID string `json:"instance_uuid"`
// NewInstanceTypeID In resize case, the flavor ID for resizing the server.
// In the other cases, this parameter is same as the flavor ID of the server when the migration was started.
NewInstanceTypeID int `json:"new_instance_type_id"`
// OldInstanceTypeID The flavor ID of the server when the migration was started.
OldInstanceTypeID int `json:"old_instance_type_id"`
// SourceCompute The source compute for a migration.
SourceCompute string `json:"source_compute"`
// SourceNode The source node for a migration.
SourceNode string `json:"source_node"`
// Status The current status of the migration.
Status string `json:"status"`
// UpdatedAt The date and time when the resource was updated.
UpdatedAt string `json:"updated_at"`
// MigrationType The type of the server migration. This is one of live-migration, migration, resize and evacuation.
MigrationType string `json:"migration_type"`
// Links Links to the migration. This parameter is returned if the migration type is live-migration and the
// migration status is one of queued, preparing, running and post-migrating.
Links interface{} `json:"links"`
// Uuid The UUID of the migration.
Uuid string `json:"uuid"`
// MigrationsLinks Links pertaining to the migration. This parameter is returned when paging and more data is available.
MigrationsLinks interface{} `json:"migrations_links"`
// UserID The ID of the user which initiated the server migration. The value may be null for older migration records.
UserID string `json:"user_id"`
// ProjectID The ID of the project which initiated the server migration. The value may be null for older migration records.
ProjectID string `json:"project_id"`
}
func ExtractMigration ¶
func ExtractMigration(r pagination.Page) ([]Migration, error)
ExtractMigration interprets a page of results as a slice of Migration.
type MigrationsPage ¶
type MigrationsPage struct {
pagination.LinkedPageBase
}
MigrationsPage stores a single page of all Network results from a List call.
func (MigrationsPage) IsEmpty ¶
func (page MigrationsPage) IsEmpty() (bool, error)
IsEmpty determines whether or not a NetworkPage is empty.
func (MigrationsPage) NextPageURL ¶
func (page MigrationsPage) NextPageURL() (string, error)
