Types

type Configurer

type Configurer struct {

	// If non-empty, use this for container DNS search.
	ClusterDomain string
	// The path to the DNS resolver configuration file used as the base to generate
	// the container's DNS resolver configuration file. This can be used in
	// conjunction with clusterDomain and clusterDNS.
	ResolverConfig string
	// contains filtered or unexported fields
}

Configurer is used for setting up DNS resolver configuration when launching pods.

func NewConfigurer

func NewConfigurer(recorder record.EventRecorder, nodeRef *v1.ObjectReference, nodeIP net.IP, clusterDNS []net.IP, clusterDomain, resolverConfig string) *Configurer

NewConfigurer returns a DNS configurer for launching pods.

func (*Configurer) CheckLimitsForResolvConf

func (c *Configurer) CheckLimitsForResolvConf()

CheckLimitsForResolvConf checks limits in resolv.conf.

func (*Configurer) GetClusterDNS

func (c *Configurer) GetClusterDNS(pod *v1.Pod) ([]string, []string, []string, bool, error)

GetClusterDNS returns a list of the DNS servers, a list of the DNS search domains of the cluster, and a list of resolv.conf options. TODO: This should return a struct.

func (*Configurer) SetupDNSinContainerizedMounter

func (c *Configurer) SetupDNSinContainerizedMounter(mounterPath string)

SetupDNSinContainerizedMounter replaces the nameserver in containerized-mounter's rootfs/etc/resolve.conf with kubelet.ClusterDNS
