How to Implement Kubernetes as Orchestrator?

  • Increases the human cost of running services
  • Increases the complexity of running services
  • Setting up services manually
  • Increase the size of bills from public cloud providers
  • Manual work of fixing if a node crashes

What is an Orchestrator?

An orchestrator is a system or tool that deploys and manages applications that can be deployed dynamically and respond to the changes made by the developers. As a result, your business can leverage benefits such as deploying your application, scale up and down dynamically based on demand. Moreover, an orchestrator also helps in self-healing during a breakdown, zero downtime rolling updates and roll-backs, and many more.

  1. To understand Kubernetes, we need to have basic knowledge about where Kubernetes are effective.
    Containerized Application — App that runs in the container
  2. Cloud-native app — The application that can satisfy business demand such as self-healing and rolling updates.
  3. Microservices app — Application built from a small program or part that forms an application.

Kubernetes Tutorial: Kubernetes vs. Docker Swarm

Kubernetes and Docker Swarm are the most used containers orchestration tools in today’s market. But over the years, Kubernetes are a clear winner in this race with the largest market shares.
Kubernetes, when compared with Docker Swarm, owns a great active community and impacts many high-scaling organizations. On the other hand, Swarm is easy to set up, but it is limited to its APIs.

What is Kubernetes?

Kubernetes is an immutable, operable, open-source platform for managing containerized workloads and services that facilitates declarative configuration and automation. It has a large, rapidly growing ecosystem.

Aspects of Kubernetes:

At the highest level, Kubernetes includes two things:

  1. Cluster for running applications.
  2. Orchestrator for cloud-native microservices apps

Kubernetes as Cluster:

Unlike any other cluster, Kube is a combination of a set of nodes and a control panel. Where the control panel showcases the API’s scheduler for the tasks that are to be assigned to nodes and states. Nodes are the points Where application services are running.

Kubernetes as Orchestrator:

As an orchestrator, Kube takes care of deploying and management of the applications. Kube organizes everything into an app and makes sure everything is running smoothly.

  • Automated Scheduling
  • Kubernetes provides an advanced scheduler to launch a container on cluster nodes.
  • Self Healing Capabilities
  • Rescheduling, replacing, and restarting the dead containers.
  • Automated rollouts and rollback
  • Kubernetes supports rollouts and rollbacks for the desired state of the containerized application.
  • Horizontal Scaling and Load Balancing
  • Kubernetes can scale up and scale down the application as per the requirements.

Kubernetes Architecture:

Kubernetes Architecture has the following main components:

  • Master nodes
  • Worker/Slave nodes

Master (Control Panel)

Master is responsible for collecting the system services that make up the control of the cluster. In other words, it has entry points for all administrative tasks. A cluster can have more than one master node for fault tolerance.

  1. API Server
  2. Controller Manager
  3. Scheduler and ETCD.
  1. Monitoring API server for a new work assignment.
  2. Execute new work assignment
  3. Report back to the control plane through API server
  1. Kubelet
  2. Container run time
  3. Kube-proxy
  • A single IP address
  • Share localhost
  • A shared IPC space
  • A shared network port range
  • Shared volumes
  • Communication between the Pods cab happen without network address translation
  • Without NAT, Nodes too can communicate with Pods.
  • The IP of Pod looks for the same IP as other pods do the same for themselves.
  1. Container to Container transfers
  2. Pod to pod transfers
  3. Pod to service transfers
  4. Internet to service transfers
