func CalculateMachineNetworkCIDR ¶

func CalculateMachineNetworkCIDR(apiVip string, ingressVip string, hosts []*models.Host) (string, error)

* Calculate the machine network CIDR from the one of (ApiVip, IngressVip) and the ip addresses of the hosts. * The ip addresses of the host appear with CIDR notation. Therefore, the network can be calculated from it. * The goal of this function is to find the first network that one of the vips belongs to it. * This network is returned as a result.

func GenerateAPIVipMAC ¶

func GenerateAPIVipMAC(clusterID string) string

func GenerateIngressVipMAC ¶

func GenerateIngressVipMAC(clusterID string) string

func GetEncodedDhcpParamFileContents ¶

func GetEncodedDhcpParamFileContents(cluster *common.Cluster) (string, error)

func GetMachineCIDRHosts ¶

func GetMachineCIDRHosts(log logrus.FieldLogger, cluster *common.Cluster) ([]*models.Host, error)

func GetMachineCIDRInterface ¶

func GetMachineCIDRInterface(host *models.Host, cluster *common.Cluster) (string, error)

func IpInCidr ¶

func IpInCidr(ipAddr, cidr string) (bool, error)

func IpInFreeList ¶

func IpInFreeList(hosts []*models.Host, vipIPStr, network string, log logrus.FieldLogger) bool

This is best effort validation. Therefore, validation will be done only if there are IPs in free list

func IsHostInMachineNetCidr ¶

func IsHostInMachineNetCidr(log logrus.FieldLogger, cluster *common.Cluster, host *models.Host) bool

func VerifyCIDRsNotOverlap ¶

func VerifyCIDRsNotOverlap(aCidrStr, bCidrStr string) error

func VerifyClusterCIDRsNotOverlap ¶

func VerifyClusterCIDRsNotOverlap(machineNetworkCidr, clusterNetworkCidr, serviceNetworkCidr string) error

func VerifyMachineCIDR ¶

func VerifyMachineCIDR(machineCidr string, hosts []*models.Host, log logrus.FieldLogger) error

func VerifyNetworkHostPrefix ¶

func VerifyNetworkHostPrefix(prefix int64) error

func VerifySubnetCIDR ¶

func VerifySubnetCIDR(cidrStr string) error

SubnetCIDR checks if the given IP net is a valid CIDR.

func VerifyVip ¶

func VerifyVip(hosts []*models.Host, machineNetworkCidr string, vip string, vipName string, mustExist bool, log logrus.FieldLogger) error

func VerifyVips ¶

func VerifyVips(hosts []*models.Host, machineNetworkCidr string, apiVip string, ingressVip string, mustExist bool, log logrus.FieldLogger) error
