Functions ¶

func GetDNS ¶

func GetDNS(subnet string) (string, error)

GetDNS parses a subnet in CIDR format as defined by RFC 4632 and RFC 4291 and returns the IP address of the Cluster DNS. Example: 172.30.0.0/16 returns 172.30.0.10

func GetProxyVars ¶

func GetProxyVars() map[string]string

GetProxyVars returns a map of the proxy variables and values from the WMCO container's environment. The presence of any implies a proxy is enabled, as OLM would have injected them into the operator spec. Returns an empty map otherwise.

func IsProxyEnabled ¶

func IsProxyEnabled() bool

IsProxyEnabled returns whether a global egress proxy is active in the cluster

func NewClusterNetworkCfg ¶

func NewClusterNetworkCfg(serviceCIDR, vxlanPort string) (*clusterNetworkCfg, error)

NewClusterNetworkCfg assigns a serviceCIDR value and returns a pointer to the clusterNetworkCfg struct

func ValidateCIDR ¶

func ValidateCIDR(cidr string) error

ValidateCIDR uses the parseCIDR from network package to validate the format of the CIDR

Types ¶

type Config ¶

type Config interface {
	// Validate checks if the cluster configurations are as required.
	Validate(context.Context) error
	// Platform returns cloud provider on which OpenShift is running
	Platform() oconfig.PlatformType
	// Network returns network configuration for the OpenShift cluster
	Network() Network
	// TLSProfileSpec returns the TLS profile spec fetched from the APIServer
	TLSProfileSpec() oconfig.TLSProfileSpec
	// TLSAdherencePolicy returns the TLS adherence policy fetched from the APIServer
	TLSAdherencePolicy() oconfig.TLSAdherencePolicy
}

Config interface contains methods to expose cluster config related information

func NewConfig ¶

func NewConfig(ctx context.Context, restConfig *rest.Config) (Config, error)

NewConfig returns a Config struct pertaining to the cluster configuration

type Network ¶

type Network interface {
	Validate(context.Context) error
	GetServiceCIDR() string
	VXLANPort() string
}

Network interface contains methods to interact with cluster network objects
