Multi Container Pod

In this training, we will work with a Pod which contains 2 containers.

Navigate to the folder 04_multi-container-pods from CLI, before you get started.

Inspect pod-v1.yaml definition file and create the pod

cat pod-v1.yaml
kubectl create -f pod-v1.yaml

kubectl logs -f my-pod

This will not work, please follow the instructions or consult --help.

Exec into the multi-container pod
```
kubectl exec -it my-pod -- /bin/sh
```
Pay attention to the output.

Find out how to exec into container-b of the Pod

kubectl exec -it my-pod -c container-b -- /bin/sh

Inspect pod-v2.yaml definition file and re-create the pod
```
cat pod-v2.yaml
kubectl replace --force -f pod-v2.yaml
```
Verify the output from container-b
```
kubectl logs -f my-pod -c container-b
```
