kubernetes-training

• In worker’s node, container is encapsulated in pod
• Pod: is an instance of an application, smallest object in kubernetes
• If there’s an increasing in demands accessing the pod, another pod will be created (i.e: 2 instances of applications running on 2 seperate pods )
• Pod has a 1:1 relationship with container

Multi-Container PODs

• A single pod can have multiple containers (typically not the same kind)
• An example is “helper container”
• The 2 containers can also connect to each other by local host since they share the same network space

kubectl

• --image : to specify images

1. To get info about a specific pod kubectl get pods kubectl get pods -o wide
