Types ¶
type IptablesManager ¶
type IptablesManager struct {
// contains filtered or unexported fields
}
IptablesManager manages the iptables-related configuration for Cilium.
func (*IptablesManager) Init ¶
func (m *IptablesManager) Init()
Init initializes the iptables manager and checks for iptables kernel modules availability.
func (*IptablesManager) InstallProxyRules ¶ added in v1.6.0
func (m *IptablesManager) InstallProxyRules(proxyPort uint16, ingress bool, name string) error
func (*IptablesManager) InstallRules ¶
func (m *IptablesManager) InstallRules(ifName string) error
InstallRules installs iptables rules for Cilium in specific use-cases (most specifically, interaction with kube-proxy).
func (*IptablesManager) RemoveProxyRules ¶ added in v1.6.0
func (m *IptablesManager) RemoveProxyRules(proxyPort uint16, ingress bool, name string) error
func (*IptablesManager) RemoveRules ¶
func (m *IptablesManager) RemoveRules()
RemoveRules removes iptables rules installed by Cilium.
func (*IptablesManager) TransientRulesEnd ¶ added in v1.5.6
func (m *IptablesManager) TransientRulesEnd()
TransientRulesEnd removes Cilium related rules installed from TransientRulesStart.
func (*IptablesManager) TransientRulesStart ¶ added in v1.5.6
func (m *IptablesManager) TransientRulesStart(ifName string) error
TransientRulesStart installs iptables rules for Cilium that need to be kept in-tact during agent restart which removes/installs its main rules. Transient rules are then removed once iptables rule update cycle has completed. This is mainly due to interactions with kube-proxy.
