Functions ¶

func GetIptablesVersion ¶ added in v0.20.0

func GetIptablesVersion(exec utilexec.Interface) (int, int, int, error)

GetIptablesVersion returns the major minor and patch version of iptables which will all be zero in case of error, and any error encountered.

Types ¶

type Chain ¶

type Chain string

const (
	ChainPostrouting Chain = "POSTROUTING"
	ChainPrerouting  Chain = "PREROUTING"
	ChainOutput      Chain = "OUTPUT"
)

type Interface ¶

type Interface interface {
	// EnsureChain checks if the specified chain exists and, if not, creates it.  If the chain existed, return true.
	EnsureChain(table Table, chain Chain) (bool, error)
	// FlushChain clears the specified chain.  If the chain did not exist, return error.
	FlushChain(table Table, chain Chain) error
	// DeleteChain deletes the specified chain.  If the chain did not exist, return error.
	DeleteChain(table Table, chain Chain) error
	// EnsureRule checks if the specified rule is present and, if not, creates it.  If the rule existed, return true.
	EnsureRule(position RulePosition, table Table, chain Chain, args ...string) (bool, error)
	// DeleteRule checks if the specified rule is present and, if so, deletes it.
	DeleteRule(table Table, chain Chain, args ...string) error
	// IsIpv6 returns true if this is managing ipv6 tables
	IsIpv6() bool
}

An injectable interface for running iptables commands. Implementations must be goroutine-safe.

func New ¶

func New(exec utilexec.Interface, protocol Protocol) Interface

New returns a new Interface which will exec iptables.

type Protocol ¶ added in v0.5.1

type Protocol byte

const (
	ProtocolIpv4 Protocol = iota + 1
	ProtocolIpv6
)

type RulePosition ¶ added in v0.18.0

type RulePosition string

const (
	Prepend RulePosition = "-I"
	Append  RulePosition = "-A"
)

type Table ¶

type Table string

const (
	TableNAT Table = "nat"
)
