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.
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 (
