When a pod is stopped or when it crashes, all the data related to it is lost.

Kubernetes volumes:

For the data to persist beyond the lifecycle of a podwe write it to a volume - directory on the host mounted inside the pod -.


We can configure the pod to use a directory on the host as its own storage.

Below the Yaml configuration file of a pod with its attached volume:


To have access to the directory on the node, the directory is mounted on a mountpoint - directory - inside the container.

We can create our pod using the below command:


If the
pod is deleted the data persists on the host. This solution works better in a single node scenario.

Different types of storage:

We have different type of storage types like 
NFS, cephfs, ...
Below we use AWS for our storage:
