It gets the configuration of a pod from the kube-apiserver and ensures that the described containers are up and running.
These contains the pod and all necessary services to ensure the pods function properly.Īn agent that runs on each node in the cluster.
#ISTIO ON DOCKER FOR MAC CODE#
This is a new feature which runs controllers that interact with the underlying cloud providers.Īllowing cloud vendors code and the Kubernetes core to evolve independent of each other. That is to noticing and responding when nodes go down or maintaining the correct number of pods of cluster.Ĭloud-controller-manager This uses apiserver to watch the shared state of the cluster and makes corrective changes to the current state to change it to the desired one. This is responsible for deploying configured pods and services onto the nodes. Simple HA key-value store for storing configuration and cluster data. This is the part of the Kubernetes Master that is provides API for all the REST communication used to control the cluster. This the cluster’s control plane, responsible for orchestrates the minions. This is responsible for managing the cluster. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applicationsĪ Kubernetes setup consists of several parts some mandatory for the whole system to function.
Coupled with features like load balancing, monitoring/health checks, replication, auto scaling and being able to roll updates with little overhead. Deploying and management multiple instances of these stateless services can be a challenge if not organized properly. The Processes factor of 12 factors which means having stateless services, that can be easily scaled by deploying multiple instances of the same service.
