func CheckAppPortsListening(
ctx context.Context,
execClient exec.Client,
podName string,
containerPortMapping map[string][]int,
timeout time.Duration,
) error
CheckAppPortsListening checks whether all the specified ports are really opened and in LISTEN mode in each corresponding container of the pod specified. It does so by periodically looking inside the container for listening connections until it finds each of the specified ports, or until the specified timeout has elapsed.
func DetectRemotePortsBoundOnLoopback(ctx context.Context, execClient exec.Client, podName string, containerName string, ports []api.ForwardedPort) ([]api.ForwardedPort, error)
DetectRemotePortsBoundOnLoopback filters the given ports by returning only those that are actually bound to the loopback interface in the specified container.

func GetConnections(ctx context.Context, execClient exec.Client, podName string, containerName string, statePredicate func(state int) bool) ([]Connection, error)
GetConnections retrieves information about connections in the specified container. It works by parsing information from the /proc/net/{tcp,tcp6,udp,udp6} files, and is able to parse both IPv4 and IPv6 addresses. See https://www.kernel.org/doc/Documentation/networking/proc_net_tcp.txt for more information about the structure of these files. The specified predicate allows to filter the connections based on the state.
func GetListeningConnections(ctx context.Context, execClient exec.Client, podName string, containerName string) ([]Connection, error)
GetListeningConnections retrieves information about ports being listened and on which local address in the specified container. It works by parsing information from the /proc/net/{tcp,tcp6,udp,udp6} files, and is able to parse both IPv4 and IPv6 addresses. See https://www.kernel.org/doc/Documentation/networking/proc_net_tcp.txt for more information about the structure of these files.
