Kubernetes concepts. Kubernetes is a container management system. It runs and manages containerized applications on a cluster. What does that really mean? Basic things we can ask Kubernetes to do. Start 5 containers using image atseashop/api:v1.3. Place an internal load balancer in front of these container The Kubernetes master controls each node; you'll rarely interact with nodes directly. A pod is a Kubernetes abstraction that represents a group of one or more application containers (such as Docker or rkt), and some shared resources for those containers These labels are supported: api-review, tide/merge-method-merge, tide/merge-method-rebase, tide/merge-method-squash, team/katacoda.
