Kubernetes is an open-source orchestration platform to deploy, control and scale containers.

Kubernetes Explained

Modern applications are rapidly being developed using containers that are microservices bundled with their dependencies and configurations Kubernetes is an open-source platform for deploying and controlling these containers on a scale. Create, develop and scale containerized applications faster with Kubernetes, often referred to as “k8s” or “k-eights.”

The working of Kubernetes

When systems expand across multiple containers distributed across multiple servers, running them becomes more complex. To handle this complexity, Kubernetes offers an open-source API that manages how and where the containers can operate.

Kubernetes organizes clusters of virtual machines and schedules containers to operate on virtual machines based on their required computational power and the resource needs of each container. Containers are clustered into pods, the basic operating unit for Kubernetes, and these pods are scaled to the desired state.

Kubernetes also dynamically handles service discovery, implements load balancing, monitors resource utilization and scales depending on compute consumption. It also monitors the wellbeing of individual resources and allows users to self-cure by automatically restarting or replicating containers.

Reasons to use Kubernetes

Keeping containerized applications up and running can be complicated, as they often require multiple containers distributed around separate machines. Kubernetes offers a way to plan and deploy these containers – plus scale them to your ideal state and control their life cycles. Using Kubernetes to implement the container-based software in a lightweight, scalable and extensible manner.

• Render compact workloads
  As container apps are different from their infrastructure, they become portable when you run them on Kubernetes. Shift them from local computers to development across on-site, hybrid and various cloud systems – all while ensuring continuity across environments.
• Quick to scale containers
  Define and deploy complex containerized systems through a cluster of servers or even several clusters of Kubernetes. As Kubernetes scales applications to your ideal state, it automatically tracks and manages container health.
• Develop more extensible applications
  A broad open-source group of developers and businesses is actively developing extensions and plugins that add features such as security, tracking and management to Kubernetes. Plus, the Approved Kubernetes Conformance Software allows any Kubernetes version to accept APIs that make it easy to use such community offerings.

Build on a complete Kubernetes platform

Although Kubernetes itself provides portability, scalability and extensibility, incorporating end-to-end development, operations and protection control enables you to deliver upgrades faster and save time on infrastructure maintenance without losing security or reliability. Often think integrating the following when you embrace Kubernetes:

• Automation of networks or serverless Kubernetes to remove repetitive functions such as provisioning, patching and updating.
• Containerized app development tools and continuous integration and continuous deployment (CI/CD) workflows.
• Safety, governance, identification and access management services.

Harness Kubernetes with DevOps

If the Kubernetes app expands – incorporating containers, habitats and teams – release frequency continues to increase, along with its developmental and organizational sophistication. The use of DevOps practices in Kubernetes environments helps you to move easily on a scale of improved stability.

• Delivery of CI/CD code quicker
  Although containers have a standardized application packaging format that encourages cooperation between production and operating teams, CI/CD can accelerate the transition from code to container and to the Kubernete cluster in minutes by automating certain activities.

• Manage technology capital easily as a code
  Infrastructure as a code guarantees continuity and visibility of computed capital across teams – reducing the probability of human error. This practice fits with the declarative design of Helm-powered Kubernetes applications. Combining the two enables you to identify apps, services and settings in a secure, trackable and repeatable manner.

• Accelerate feedback loop with continuous tracking
  Shorten the time between vulnerabilities and updates with a full view of the tools, cluster, Kubernetes API, containers and coding – from container health management to centralized logging. This view lets you avoid resource bottlenecks, monitor malicious requests, and keep your Kubernetes applications secure.

• Balancing pace and security with DevOps
  Add real-time observability to the DevOps workflow without compromising pace. Apply compliance checks and reconfigurations automatically to protect your pipeline install and release – and, as a result, your Kubernetes program.

Examples of DevOps Kubernetes workflow

• Quickly iterate, validate and debug the various parts of the program together in the same Kubernetes cluster.
• Merge and review the code in the GitHub repository for continuous integration. And run automatic prototypes and experiments as part of continuous execution.
• Verify the origins and integrity of the photographs in the container. Images are placed in quarantine until they are scanned.
• Provision Kubernetes clusters with software such as Terraform. Helm maps installed by Terraform describe the optimal state of device services and configurations.
• Enforce policies that control deployments to the Kubernetes cluster.
• The release pipeline automatically applies a predefined distribution strategy for each code.
• Enable app telemetry, container health tracking, and real-time log review.
• Add policy audit and automated remediation to the IC/CD pipeline. For eg, only the release pipeline has permission to build new pods in your Kubernetes environment.
• Fix problems with experience and advise the preparations for the next sprint.
