Guide

Run a pod / container:

ig

$ docker run --name test-snapshot-process -d busybox /bin/sh -c 'sleep inf'
...

Then, run the gadget and see how it shows the sleep process:

kubectl gadget

$ kubectl gadget run snapshot_process:latest
K8S.NODE            K8S.NAMESPACE       K8S.PODNAME         K8S.CONTAINERNAME   COMM              PID        TID        UID        GID       PPID
minikube-docker     default             test-snap…t-process test-snapshot-proce sh             530932     530932          0          0     530911
^C

ig

$ sudo ig run snapshot_process:latest -c test-snapshot-process
RUNTIME.CONTAINERNAME           COMM                            PID               TID              UID              GID             PPID
test-snapshot-process           sh                           524665            524665                0                0           524645
^C

Finally, clean the system:

kubectl gadget

$ kubectl delete pod test-snapshot-process

ig

$ docker rm -f test-snapshot-process
