Then, run the gadget and see how it shows the sockets used by nginx:

kubectl gadget

$ kubectl gadget run snapshot_socket:latest
K8S.NODE            K8S.NAMESPACE         K8S.PODNAME           K8S.CONTAINERNAME     SRC                        DST                        STATE
minikube-docker     default               test-snapshot-socket  test-snapshot-socket  :::80                      :::0                       10
minikube-docker     default               test-snapshot-socket  test-snapshot-socket  0.0.0.0:80                 0.0.0.0:0                  10
^C

ig

$ sudo ig run snapshot_socket:latest -c test-snapshot-socket
RUNTIME.CONTAINERNAME              SRC                                           DST                                          STATE
test-snapshot-socket               :::80                                         :::0                                         10
test-snapshot-socket               0.0.0.0:80                                    0.0.0.0:0                                    10

Finally, clean the system:

kubectl gadget
