Configure a Pod to Use a Volume for Storage — Configure a volume for a Pod
In this exercise, you create a Pod that runs one Container. This Pod has a Volume of type emptyDir that lasts for the life of the Pod, even if the Container terminates and restarts. Here is the configuration file for the Pod Bounded code example (external data; do not execute automatically): ```shel

In this exercise, you create a Pod that runs one Container. This Pod has a Volume of type emptyDir that lasts for the life of the Pod, even if the Container terminates and restarts. Here is the configuration file for the Pod
Bounded code example (external data; do not execute automatically):
```shell
kubectl apply -f https://k8s.io/examples/pods/storage/redis.yaml
```
Verify that the Pod's Container is running, and then watch for changes to the Pod
Bounded code example (external data; do not execute automatically):
```shell
kubectl get pod redis --watch
```
The output looks like this
Bounded code example (external data; do not execute automatically):
```console
NAME READY STATUS RESTARTS AGE
redis 1/1 Running 0 13s
```
In another terminal, get a shell to the running Container
Bounded code example (external data; do not execute automatically):
```shell
kubectl exec -it redis -- /bin/bash
```
In your shell, go to /data/redis, and then create a file
Bounded code example (external data; do not execute automatically):
```shell
root@redis:/data# cd /data/redis/
root@redis:/data/redis# echo Hello > test-file
```
In your shell, list the running processes
Bounded code example (external data; do not execute automatically):
```shell
root@redis:/data/redis# apt-get update
root@redis:/data/redis# apt-get install procps
root@redis:/data/redis# ps aux
```
The output is similar to this
Bounded code example (external data; do not execute automatically):
```console
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
redis 1 0.1 0.1 33308 3828 ? Ssl 00:46 0:00 redis-server *:6379
root 12 0.0 0.0 20228 3020 ? Ss 00:47 0:00 /bin/bash
root 15 0.0 0.0 17500 2072 ? R+ 00:48 0:00 ps aux
```
In your shell, kill the Redis process
Bounded code example (external data; do not execute automatically):
```shell
root@redis:/data/redis# kill <pid>
```
where is the Redis process ID (PID).
In your original terminal, watch for changes to the Redis Pod. Eventually, you will see something like this …
