func ConfigToAdditionalVMs

func ConfigToAdditionalVMs(c config.Config) []bosh.VM

ConfigToAdditionalVMs creates a list of additional non-bosh VMs to migrate

func ConfigToSourceClustersByAZ

func ConfigToSourceClustersByAZ(c config.Config) map[string][]string

ConfigToSourceClustersByAZ creates a map of AZs to their source clusters

func ConfigToTargetHostPoolConfig

func ConfigToTargetHostPoolConfig(c config.Config) *vcenter.HostPoolConfig

ConfigToTargetHostPoolConfig creates the required configuration format to create a target host pool

func ConfigToVCenterClientPool

func ConfigToVCenterClientPool(c config.Config) *vcenter.Pool

ConfigToVCenterClientPool creates a pool of VCenter clients for each AZ source and target

Types

type BoshClient

type BoshClient interface {
	VMsAndStemcells(context.Context) ([]bosh.VM, error)
}

func ConfigToBoshClient

func ConfigToBoshClient(c config.Config) BoshClient

ConfigToBoshClient creates an optional bosh client if configured, other a null object (pattern)

type FoundationMigrator

type FoundationMigrator struct {
	WorkerCount   int
	AdditionalVMs []bosh.VM
	// contains filtered or unexported fields
}

FoundationMigrator orchestrates the entire migration of a foundation

func NewFoundationMigrator

func NewFoundationMigrator(
	clientPool *vcenter.Pool,
	boshClient BoshClient,
	vmMigrator *VMMigrator,
	srcAZsToClusters map[string][]string,
	out *log.UpdatableStdout) *FoundationMigrator

NewFoundationMigrator creates a new initialized FoundationMigrator using the provided instances

func NewFoundationMigratorFromConfig

func NewFoundationMigratorFromConfig(c config.Config) (*FoundationMigrator, error)

NewFoundationMigratorFromConfig creates a new FoundationMigrator instance from the specified config

func (*FoundationMigrator) Migrate

func (f *FoundationMigrator) Migrate(ctx context.Context) error

Migrate executes the entire migration for all VMs

type NullBoshClient

type NullBoshClient struct{}

NullBoshClient is a null object pattern when no bosh client is specified in the config

func (NullBoshClient) VMsAndStemcells

func (c NullBoshClient) VMsAndStemcells(context.Context) ([]bosh.VM, error)

VMsAndStemcells returns an empty list

type UpdatableLogger
