| In fact, all of the above features can be implemented as long as one set of containers share some Linux Namespaces and mount the same volume. Below, we will analyze how the CRI Manager in PouchContainer implements the Pod model by creating a Pod: | ||
|
|
||
| 1. When Kubelet creating a Pod, the CRI `RunPodSandbox` would be called first. The implementation of the interface by CRI Manager is to create a special container, called "infra container". | ||
| From the point of view of the container implementation, it is not special, it is nothing but call the Container Manager and create a normal container with image named `pause-amd64:3.0`. But form the perspective of the whole Pod container group, it has special role, which contributes its own Linux Namespace as Linux shared namespace of the container mentioned above, connecting all containers in the container group. It is more like a carrier that carries all the other containers in the Pod and provides the infrastructure for their operation. In general, we also use an infra container to represent a Pod. |

| ### 4. Realization of Pod Model | |||
|
|

| In the world of Kubernetes, Pod is the smallest scheduling deployment unit. In brief, a Pod is a container group composed of relavent container. As a whole, these "intimate" containers will share something to make their interaction more efficient. For example, for network, containers within same Pod will share same IP address and port, so that they can access eachother through localhost. For storage, volume defined in Pod will mount to every container, so that every container can access it. | |||
