Sharing volumes between containers in the same Pod
In this section, we'll learn what volumes are from a Kubernetes point of view and how to use them. Docker also has a notion of volumes but it differs from Kubernetes volumes: they answer the same need but they are not the same.
In this section, we will discover what Kubernetes volumes are, why they are useful, and how they can help us when it comes to Kubernetes volumes.
What are Kubernetes volumes?
We are going to answer a simple problem. Our multi-container Pods are currently made up of two containers: an NGINX one and a Busybox one. We are going to try to share the log directory in the NGINX container with the Busybox container by mounting the log directory of NGINX in the directory of the Busybox container. This way, we will create a relationship between the two containers to have them share a directory.
Kubernetes has two kinds of volumes:
- Volumes, which we will discuss here.
PersistentVolume, which...
