func BlockNetwork

func BlockNetwork(from string, to string)

The following helper functions can block/unblock network from source host to destination host by manipulating iptable rules. This function assumes it can ssh to the source host.

Suggested usage pattern: func foo() {

...
defer UnblockNetwork(from, to)
BlockNetwork(from, to)
...

func CreatePVCPV added in v1.6.0

Create a PVC followed by the PV based on the passed in nfs-server ip and namespace. If the "preBind" bool is true then pre-bind the PV to the PVC via the PV's ClaimRef. Return the pv and pvc to reflect the created objects. Note: in the pre-bind case the real PVC name, which is generated, is not

known until after the PVC is instantiated. This is why the pvc is created
before the pv.

If a Create error occurs, the returned maps may contain pv and pvc entries for the resources that were successfully created. In other words, when the caller sees an error returned, it needs to decide what to do about entries in the maps. Note: when the test suite deletes the namespace orphaned pvcs and pods are deleted. However,

orphaned pvs are not deleted and will remain after the suite completes.
