Functions ¶
func BuildDirector ¶

func BuildUAA ¶
Build an UAA based on the UAA URL from the configuration @param config Initialized config struct from github.com/evoila/infraTESTure/config @return uaa Initialized uaa struct from github.com/cloudfoundry/bosh-cli/uaa
func InitInfrastructureValues ¶
Initialize the Bosh Director and the Deployment affiliated to the deployment name in the config @param config Configuration struct from github.com/evoila/infraTESTure/config
func ParseDiskSize ¶
SSH to vm and run df command in order to get the free disk space then filter the one needed @param vmId Id of the VM you want to determine used and available disk space from @return used Value in bytes of used disk space @return available Value in bytes of available disk space
Types ¶
type Bosh ¶
type Bosh struct{}
func (*Bosh) AddTrafficControl ¶
Open SSH session and run the tc command @param vmId Id of the VM you want to add traffic control to @param tc String containing the tc command, from one or more of the previous functions. TC commands can be connected. For example you can run the "SimulatePackageLoss" function and afterwards expand the resulting string with "SimulateNetworkDelay"
func (*Bosh) AssertEquals ¶
func (*Bosh) AssertFalse ¶
func (*Bosh) AssertNotEquals ¶
func (*Bosh) AssertNotNil ¶
func (*Bosh) AssertTrue ¶
