Types

type PolicyManager

type PolicyManager struct {
	sync.Mutex
	// contains filtered or unexported fields
}

iptable egress chain topology is like

FORWARD            GLX-POD-XXXX - GLX-PLCY-XXXX
      \           /            \ /
       GLX-EGRESS              /\
      /           \           /  \
INPUT             GLX-POD-XXXX - GLX-PLCY-XXXX

func NewPolicyManager

func NewPolicyManager(
	client kubernetes.Interface,
	networkPolicyInformer networkingformers.NetworkPolicyInformer,
	quitChan <-chan struct{}) *PolicyManager

func (*PolicyManager) AddPod

func (p *PolicyManager) AddPod(pod *corev1.Pod) error

func (*PolicyManager) AddPolicy

func (p *PolicyManager) AddPolicy(policy *networkv1.NetworkPolicy) error

func (*PolicyManager) DeletePod

func (p *PolicyManager) DeletePod(pod *corev1.Pod) error

func (*PolicyManager) DeletePolicy

func (p *PolicyManager) DeletePolicy(policy *networkv1.NetworkPolicy) error

func (*PolicyManager) Run

func (p *PolicyManager) Run()

func (*PolicyManager) SyncPodChains

func (p *PolicyManager) SyncPodChains(pod *corev1.Pod) error

#lizard forgives SyncPodChains ensures GLX-INGRESS/GLX-EGRESS/GLX-POD-XXXX iptable chains are expected

func (*PolicyManager) SyncPodIPInIPSet

func (p *PolicyManager) SyncPodIPInIPSet(pod *corev1.Pod, add bool)

SyncPodIPInIPSet ensures pod ip is expected in each policy's ipset. ipset is already created because we have these policies in memory

func (*PolicyManager) UpdatePod

func (p *PolicyManager) UpdatePod(oldPod, newPod *corev1.Pod) error

func (*PolicyManager) UpdatePolicy

func (p *PolicyManager) UpdatePolicy(oldPolicy, newPolicy *networkv1.NetworkPolicy) error
