Answer 1

This is what works for me
apiVersion: v1
kind: Pod
metadata:
name: mc1
spec:
volumes:
- name: html
emptyDir: {}
containers:
- name: 1st
image: nginx
command: ["/bin/sh", "-c"]
args:
- while true; do
touch /usr/share/nginx/html/test.txt;
ls /usr/share/nginx/html/;
echo "file created cotnainer 1";
sleep infinity;
done
volumeMounts:
- name: html
mountPath: /usr/share/nginx/html
- name: 2nd
image: debian
volumeMounts:
- name: html
mountPath: /html
command: ["/bin/sh", "-c"]
args:
- while true; do
ls /html;
rm /html/test.txt;
echo "container 2 - file removed";
ls /html;
sleep 7200;
done
i am creating a file from container 1 and getting removed by container 2 what error are you getting?

Using nginx container with an alpine base you need to install crond, here is an example: Enable crond in an Alpine container
Now, you could run a cron task in the same container that has the files so you just need 1 container for the pod.
Also, here is another example on how to run crond in an alpine docker container:
