    image: rtsp/rtsp:latest

kubectl exec rtsp -- ping -c 3 10.233.0.1

kubectl exec -it rtsp -- bash

Run as Kubernetes DaemonSet

This manifests will deploy Pods in all nodes (including control-plane). Useful for network reachability debugging.

rtsp-vw45v   1/1     Running   4d16h   10.233.64.11   k8s-m1

Example: Check that k8s-m2 node (rtsp-q48n6) able to reach a pod in k8s-m1 node (10.233.64.11).

kubectl exec rtsp-q48n6 -- ping -c 3 10.233.64.11

or just run it interactively

kubectl exec -it rtsp-q48n6 -- bash

or if you don’t mind which Pod to use

kubectl exec -it daemonset/rtsp -- bash

Run as Kubernetes StatefulSet

This manifests will deploy a Pod with a 4 GiB persistent storage mounted on /data.
