Containers

Google Kubernetes (k8s) Engine (GKE)

• Kubernetes is an open-source orchestrator for containers for managing and scaling applications
• Kubernetes let’s us deploy containers on a set of nodes called cluster
• A node represents a computing instance, in GC these are Compute Engine instances (virtual machines)
• GKE: is a Kubernetes as a managed service in the cloud
• Whenever k8s deploys an container or a number of related containers, it does so in a abstraction called as a pod
• Each pod in k8s gets an unique address
• Containers in pod can communicate with each other using localhost
• To expose the containers from a pod to the public internet, we can attach a load balancer to the cluster
