Deploy a daemonset and stateful set applications, and learn about how they operate.
- [Instructor] A daemon set ensures that all nodes run…a copy of a specific pod.…As nodes are added to the cluster,…pods are added to them as well.…Example of a daemon set would be running your logging…or monitoring agent on all of your nodes.…In this example, I'm going to use a simple busy box…container and deploy it as a daemon set.…This is my yaml for the daemon set.…As you can see, it's a kind of daemon set,…with a spec of example daemon set specifically…it's an image busybox.…
Let's go ahead and deploy this.…We deploy this by the kube ctl create minus f…daemon set . yaml command.…Pretty similar to how we've done other deployments before.…To fetch them, we can do a kube ctl get daemon sets.…We notice that we have the example daemon set…up and running and it's desired, current, ready,…up to date, and available.…You'll also notice this node selector…which I'll get into in a second.…
If we look at our pods,…you'll notice that we have a pod running.…Great!…The daemon set is working as expected.…This is not something new that we haven't seen before.…
