Understanding Kubernetes (K8S): A Basic Tutorial
As a software developer, if you create a list of the best transformative technologies that have emerged over the past decade, Kubernetes would feature to the top. To know more about what is Kubernetes and why it is essential for your success, you need to have its basic understanding. So let’s move ahead!
What is Kubernetes?
Kubernetes, often known as “K8s,” compose the execution of containerized applications over a cluster of hosts. Using on-premises infrastructure or public cloud platforms, the K8s solution automates the deployment and administration of cloud-native apps.
It automates dynamic container networking and distributes application workloads throughout a Kubernetes cluster. Kubernetes also enables resiliency by allocating storage and persistent volumes to running containers, offering automatic scaling, and continuously working to maintain applications’ desired state.
Features of Kubernetes
Kubernetes includes several capabilities that enable coordinated containers across multiple hosts, automate K8s cluster administration, and maximize resource consumption through better infrastructure utilization. The following are important features:
- Auto-scaling: Scale containerized programs and their resources up or down automatically based on usage.
- Declarative model: You can Declare a particular state of your choice, and Kubernetes would run in the background to maintain that state and recover from any failures.
- Load balancing: To address diverse requirements, K8s supports both internal and external load balancing options.
Kubernetes and Docker
Docker is a free and open-source containerization technology for deploying programs in any computing environment.
Docker and Kubernetes, two modern, sophisticated technologies, handle a variety of difficulties emerging from a variety of application development backgrounds.
Using Kubernetes to run Docker Containers helps enterprises to take advantage of DevOps best practices by efficiently coordinating and orchestrating containerized applications.
By building a network of containerized apps, an enterprise can use Kubernetes with alternative container runtime interfaces, such as CRI-O and RunC, while also using Docker with other orchestration tools for communication between different nodes.
Many Azure DevOps services providers are adopting and implementing Kubernetes in their process. As Kubernetes offers a scalable cloud option, its has immensely gained popularity among developers.
