Kubernetes - File missing inside pods after reboot

In Kubernetes I create a deployment with 3 replica and it is creating 3 pods.

After Pod creation I create a property file which has all the key/value that are required for my application (on all 3 pods).

If I reboot the machine the property file inside the pods is missing.So I am creating it manually every time if the machine reboots.

Is there any way to save the property file inside the pod?

What you do depends on what the file is for and where it needs to be located.

If a config file, you may want to use a config map and mount the config map into the container.

If it needs to be long lived storage for data, create a persistent volume claim and then mount the volume into the container.

Something like this is necessary as the container file system is otherwise ephemeral and anything written to it will be lost when the container is shutdown.
