    Types

    type Client

    type Client struct {
    	// contains filtered or unexported fields
    }

      Client is the client-side API for the MigrationTarget facade. It is used by the migrationmaster worker when talking to the target controller during a migration.

      func NewClient

      func NewClient(caller base.APICaller) *Client

        NewClient returns a new Client based on an existing API connection.

        func (*Client) Abort

        func (c *Client) Abort(modelUUID string) error

          Abort removes all data relating to a previously imported model.

          func (*Client) Activate

          func (c *Client) Activate(modelUUID string) error

            Activate marks a migrated model as being ready to use.

            func (*Client) AdoptResources

            func (c *Client) AdoptResources(modelUUID string) error

              AdoptResources asks the cloud provider to update the controller tags for a model's resources. This prevents the resources from being destroyed if the source controller is destroyed after the model is migrated away.

              func (*Client) CACert

              func (c *Client) CACert() (string, error)

                CACert returns the CA certificate associated with the connection.

                func (*Client) CheckMachines

                func (c *Client) CheckMachines(modelUUID string) ([]error, error)

                  CheckMachines compares the machines in state with the ones reported by the provider and reports any discrepancies.

                  func (*Client) Import

                  func (c *Client) Import(bytes []byte) error

                    Import takes a serialized model and imports it into the target controller.

                    func (*Client) LatestLogTime

                    func (c *Client) LatestLogTime(modelUUID string) (time.Time, error)

                      LatestLogTime asks the target controller for the time of the latest log record it has seen. This can be used to make the log transfer restartable.

                      func (*Client) OpenLogTransferStream

                      func (c *Client) OpenLogTransferStream(modelUUID string) (base.Stream, error)

                        OpenLogTransferStream connects to the migration logtransfer endpoint on the target controller and returns a stream that JSON logs records can be fed into. The objects written should be params.LogRecords.

                        func (*Client) Prechecks

                        func (c *Client) Prechecks(model coremigration.ModelInfo) error

                        func (*Client) SetPlaceholderResource

                        func (c *Client) SetPlaceholderResource(modelUUID string, res resource.Resource) error

                          SetPlaceholderResource sets the metadata for a placeholder resource.

                          func (*Client) SetUnitResource

                          func (c *Client) SetUnitResource(modelUUID, unit string, res resource.Resource) error

                            SetUnitResource sets the metadata for a particular unit resource.

                            func (*Client) UploadCharm

                            func (c *Client) UploadCharm(modelUUID string, curl *charm.URL, content io.ReadSeeker) (*charm.URL, error)

                              UploadCharm sends the content to the API server using an HTTP post in order to add the charm binary to the model specified.

                              func (*Client) UploadResource

                              func (c *Client) UploadResource(modelUUID string, res resource.Resource, r io.ReadSeeker) error

                                UploadResource uploads a resource to the migration endpoint.

                                func (*Client) UploadTools

                                func (c *Client) UploadTools(modelUUID string, r io.ReadSeeker, vers version.Binary) (tools.List, error)

                                  UploadTools uploads tools at the specified location to the API server over HTTPS for the specified model.
