TODO(ihmccreery): remove once we don't care about v1.0 anymore, (tentatively in v1.3).
var SubResourceServiceAndNodeProxyVersion = utilversion.MustParseSemantic("v1.2.0")
Functions ¶
func AddOrUpdateAvoidPodOnNode ¶ added in v1.7.0

func BlockNetwork ¶
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.
Caution: Recommend to input IP instead of hostnames. Using hostnames will cause iptables to do a DNS lookup to resolve the name to an IP address, which will slow down the test and cause it to fail if DNS is absent or broken.
Suggested usage pattern:
func foo() { ... defer UnblockNetwork(from, to) BlockNetwork(from, to) ... }

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

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