Functions

func CheckSysctlValue

func CheckSysctlValue(sysctlPath, value string) error

CheckSysctlValue is a utility function to assert sysctl value is set to what is expected.

func Cmd

func Cmd(cmd string) string

func CreateContainer

func CreateContainer(netconf, podName, podNamespace, ip string) (containerID string, result *current.Result, contVeth netlink.Link, contAddr []netlink.Addr, contRoutes []netlink.Route, targetNs ns.NetNS, err error)

func CreateContainerNamespace

func CreateContainerNamespace() (containerNs ns.NetNS, containerId string, err error)

func CreateContainerWithId

func CreateContainerWithId(netconf, podName, podNamespace, ip, overrideContainerID string) (containerID string, result *current.Result, contVeth netlink.Link, contAddr []netlink.Addr, contRoutes []netlink.Route, targetNs ns.NetNS, err error)

Create container with the giving containerId when containerId is not empty

Deprecated: Please call CreateContainerNamespace and then RunCNIPluginWithID directly.

func CreateHostVeth

func CreateHostVeth(containerId, k8sName, k8sNamespace, nodename string) error

Create veth pair on host

func DeleteContainer

func DeleteContainer(netconf, netnspath, podName, podNamespace string) (exitCode int, err error)

Executes the Calico CNI plugin and return the error code of the command.

func DeleteContainerWithId

func DeleteContainerWithId(netconf, netnspath, podName, podNamespace, containerId string) (exitCode int, err error)

func DeleteContainerWithIdAndIfaceName

func DeleteContainerWithIdAndIfaceName(netconf, netnspath, podName, podNamespace, containerId, ifaceName string) (exitCode int, err error)

func GetResultForCurrent

func GetResultForCurrent(session *gexec.Session, cniVersion string) (*current.Result, error)

GetResultForCurrent takes the output with cniVersion and returns the Result in current.Result format.

func MustCreateNewIPPool

func MustCreateNewIPPool(c client.Interface, cidr string, ipip, natOutgoing, ipam bool) string

MustCreateNewIPPool creates a new Calico IPAM IP Pool.

func MustDeleteIPPool

func MustDeleteIPPool(c client.Interface, cidr string)

func RunCNIPluginWithId

func RunCNIPluginWithId(
	netconf,
	podName,
	podNamespace,
	ip,
	containerId,
	ifName string,
	targetNs ns.NetNS,
) (
	result *current.Result,
	contVeth netlink.Link,
	contAddr []netlink.Addr,
	contRoutes []netlink.Route,
	err error,
)

RunCNIPluginWithId calls CNI plugin with a containerID and targetNs passed to it. This is for when you want to call CNI for an existing container.

func RunIPAMPlugin

func RunIPAMPlugin(netconf, command, args, cniVersion string) (*current.Result, types.Error, int)

RunIPAMPlugin sets ENV vars required then calls the IPAM plugin specified in the config and returns the result and exitCode.

func WipeEtcd

func WipeEtcd()

Delete everything under /calico from etcd.

func WipeK8sPods

func WipeK8sPods()
