I created this pod:

k run hello --image=busybox --restart=Never -- echo "Hello World"

Then I am checking it :

controlplane $ k get pod
NAME     READY   STATUS      RESTARTS   AGE
hello    0/1     Completed   0          16m

The READY is 0/1, does it means that my pod lived just until execute the command “hello world”? It could be milliseconds, and the it dies?

:sauropod: Good morning, good afternoon, good night everyone :blush:
You, have a wonderful day today!

Mohamed Ihsan:
Yes

Mohamed Ihsan:
Also try with restart=Always parameter as well.

Edith Puclla:
let me try @Mohamed Ihsan :slightly_smiling_face:

Edith Puclla:
This is restarting and I have this messages:
Warning BackOff 6s (x7 over 68s) kubelet Back-off restarting failed container
hello3 0/1 CrashLoopBackOff 3 85s
Why this is CrashLoopBackOff ? this simple container does not have to fail, why does putting restart = Always make it fail? @Mohamed Ihsan :blush:

Mohamed Ihsan:
This is the normal behavior.
k8s always wanna make the pod up and running. But if the pod doesn’t have a continuous program it will stop. hence you will end up in the start-stop loop. Which is noted as CrashLoopBackOff

Mohamed Ihsan:
In the first command you have change this with restart=Never

Edith Puclla:
I got it :slightly_smiling_face: Thanks a lot

Sangeetha Radhakrishnan:
To debug CrashLoopBackOff issue, check the command set in the pod is correct or not.

Edith Puclla:
The command is good, it is an echo:

controlplane $ k logs hello3
Hello World

Alok Rahul:
In earlier version of K8s it would not crashloopbackoff, but in recent ones, it would crashloopbackoff if you run them like deployment.
This is why we have resource like jobs and cronjobs for such scenario, hence in such cases use jobs and cronjobs that will execute your task multiple times.
