For example\n\nCreate the pod nginx on your cluster\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl apply -f https://k8s.io/examples/pods/share-process-namespace.yaml\n```\n\nAttach to the shell container and run ps\n\nBounded code example (external data; do not execute automatically):\n```shell\n   kubectl exec -it nginx -c shell -- /bin/sh\n```\n\nIf you don't see a command prompt, try pressing enter. In the container shell\n\nBounded code example (external data; do not execute automatically):\n```shell\n   # run this inside the \"shell\" container\n   ps ax\n```\n\nThe output is similar to this\n\nBounded code example (external data; do not execute automatically):\n```none\n   PID   USER     TIME  COMMAND\n       1 root      0:00 /pause\n       8 root      0:00 nginx: master process nginx -g daemon off;\n      14 101       0:00 nginx: worker process\n      15 root      0:00 sh\n      21 root      0:00 ps ax\n```\n\nYou can signal processes in other containers. For example, send SIGHUP to nginx to restart the worker process. This requires the SYS_PTRACE capability.\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
